In this study an attempt is made to develop SCC mixes of different Strengths by using
various ranges of cement, Metakaolin and Fly ash with appropriate quantity of Super
plasticizer. A total of 11 (eleven) mixes has been prepared by this research. This chapter is mainly
focused on the cost analysis of the designed SCC mixes and Normal Vibrating Concrete (NVC)
mixes. The number of skilled labour, vibrator operators and the number of defects can drastically be
reduced, owing to user-friendly characteristics of SCC. The time, cost and quality are the three
important factors which assume significance in construction due to their impact on the industry as a
whole. Any development which has a positive impact on these factors is always in the interest of
civil engineering. As SCC requires a higher volume of fines replacement of cement content by
mineral admixtures like fly ash which increases the viscosity and workability of fresh concrete and
reduces the cost of SCC

Abstract
The objective of providing eco-friendly concrete is gaining hike in the global construction industry. The depleting resources have made the researchers to focus on sustainable development in all areas and more particularly in concrete production, due to the high rate of growth of industries and their infrastructure development, which increase the rate of consumption of concrete. The practice of recycling of demolished concrete for use in sub grades has already been set up. However a new concrete that is produced with such a recycled concrete seems to have higher porosity, lower strength and modulus of elasticity when compared to normal conventional concrete. Some of the earlier studies have attempted to improve the recycled material so as to reduce its high porosity. From review of literature it is found that studies under rural roads using recycled aggregates was done. This project deals with the use of recycled aggregates for rigid pavements replacing natural aggregates in rural roads. The tests are conducted for various proportion mix of Recycled aggregates and Natural aggregates.M30 grade of concrete is being used for the design .Aggregates at maximum size of 20mm is taken. The required strength for rigid pavements under recycled aggregates is being evaluated in this project. The ultimate aim is to attain a suitable strength on usage of recycled aggregates for rigid pavements in rural roads thus to implement cost effective nature and durability.

Machining tests were carried out by turning En-
31steel alloy with tungsten carbide tools using soluble oilwater
mixture lubricant under dif ferent machining
conditions. First-order and second-order surface roughness
predicting models were developed by using the experimental
data by applying response surface methodology and factorial
design of experiments. The established equations show that
the feed rate is the main influencing factor on the surface
roughness followed by tool nose radius and depth of cut. It
increases with increase in the feed rate but decreases with
increase in the cutting velocity and tool nose radius,
respectively. The predicted surface roughness values of the
samples have been f ound to lie close to that of the
experimentally observed values. There is an improvement
in surface finish by 10% with wet machining as compared
to dry machining.

The modeling of pressure distribution of fresh concrete poured in vertical formwork are rather dynamic than complex. Many researchers had worked on the pressure distribution modeling of concrete and formulated empirical relationship factors like formwork height, rate of pour, consistency classes of concrete. However, in the current scenario, most of high rise construction uses self compacting concrete(SCC) which is a special concrete which utilizes not only mineral and chemical admixtures but also varied aggregate proportions and hence modeling pressure distribution of SCC over other concrete in vertical formwork systems is necessitated. This research seeks to bridge the gap between the theoretical formulation of pressure distribution with the actual modeled (scaled) vertical formwork systems. The pressure distribution of SCC in the laboratory will be determined using pressure sensors, modeled and analyzed.

Machining tests were carried out by turning En-
31steel alloy with tungsten carbide tools using soluble oilwater
mixture lubricant under dif ferent machining
conditions. First-order and second-order surface roughness
predicting models were developed by using the experimental
data by applying response surface methodology and factorial
design of experiments. The established equations show that
the feed rate is the main influencing factor on the surface
roughness followed by tool nose radius and depth of cut. It
increases with increase in the feed rate but decreases with
increase in the cutting velocity and tool nose radius,
respectively. The predicted surface roughness values of the
samples have been f ound to lie close to that of the
experimentally observed values. There is an improvement
in surface finish by 10% with wet machining as compared
to dry machining.

Experimental Investigation of Lateral Pressure on Vertical Formwork Systems u...IJTET Journal
The modeling of pressure distribution of fresh concrete poured in vertical formwork are rather dynamic than complex. Many researchers had worked on the pressure distribution modeling of concrete and formulated empirical relationship factors like formwork height, rate of pour, consistency classes of concrete. However, in the current scenario, most of high rise construction uses self compacting concrete(SCC) which is a special concrete which utilizes not only mineral and chemical admixtures but also varied aggregate proportions and hence modeling pressure distribution of SCC over other concrete in vertical formwork systems is necessitated. This research seeks to bridge the gap between the theoretical formulation of pressure distribution with the actual modeled (scaled) vertical formwork systems. The pressure distribution of SCC in the laboratory will be determined using pressure sensors, modeled and analyzed.

DURABILITY STUDIES OF GGBS AND METAKAOLIN BASED GEOPOLYMER CONCRETE Ijciet 08...IAEME Publication
The objective of this research work was to produce a carbon dioxide emission free cementious
material. The geopolymer concrete is such a vital and promising one. In this study, geopolymer is
prepared from ‘Ground Granulated Blast Furnace Slag’ (GGBS) a powder from grinding the byproduct
of slag waste from blast furnace of steel plants and metakaolin from industry. The Alkaline
liquids used in this study for the polymerization process are the solutions of sodium hydroxide
(NaoH) and sodium silicate (Na2Sio3).A 8 Molarity and 10 Molarity solutions was taken to prepare
the mix. The cube compressive strength was calculated for different mixes. The cube specimens are
taken of size 150 mm x 150 mm x 150 mm. Ambient curing of concrete at room temperature was
adopted. In total 180 cubes were casted for their compressive strength at age of 28 days
respectively. The test data indicate that on exposure to 5% Sodium Sulphate, Sulphuric Acid and
Sodium Chloride, the losses in weight, and strength of geopolymer concrete (GPC) are
significantly much less than those for cement concrete. Thus the geopolymer concrete is considered
to be an environmentally pollution free construction material.
Self-Compacting Concrete or Self Consolidating Concrete (SCC) is a highly flowable, stable concrete which flows readily into place, filling formwork without any consolidation and without undergoing any significant segregation. The use of SCC eliminates the need for compaction therefore saving time, reducing labor costs and conserving energy.Fresh SCC must possess the key properties including filling ability, passing ability and resistance to segregation at required levels. The filling ability is the ability of the SCC to flow into all spaces within the formwork under its own weight. Without vibrating the concrete, SCC has to fill any space within the formwork and it has to flow in horizontal and vertical directions without keeping air entrapped inside the concrete or at the surface. Passing ability is the ability of the SCC to flow through tight openings such as spaces between steel reinforcing bars, under its own weight. Passing ability is required to guarantee a homogenous distribution of the components of SCC in the vicinity of obstacles. The resistance to segregation is the resistance of the components of SCC to migration or separation and remains uniform throughout the process of transport and placing.

IRJET - Experimental and Analytical Study on High Strength Concrete (M70)...IRJET Journal
This document presents the results of an experimental study on high-strength concrete (M70) using recycled concrete aggregate (RCA). Tests were conducted to determine the effect of different percentages (10%, 20%, 30%) of coarse RCA on the concrete's compressive strength, durability, and engineering properties. The results showed that replacement of up to 30% coarse RCA had no effect on concrete strength, but higher percentages led to gradual strength reductions. However, with adjustments to the water-cement ratio, high-strength concrete with RCA can achieve equivalent performance to concrete with natural aggregates. The study aims to establish RCA concrete as a viable and sustainable construction material.

A STUDY ON THE IMPACT OF ORGANIZATIONAL CULTURE ON THE EFFECTIVENESS OF PERFO...IAEME Publication
The main objective of this study is to analyze the impact of aspects of Organizational Culture on the Effectiveness of the Performance Management System (PMS) in the Health Care Organization at Thanjavur. Organizational Culture and PMS play a crucial role in present-day organizations in achieving their objectives. PMS needs employees’ cooperation to achieve its intended objectives. Employees' cooperation depends upon the organization’s culture. The present study uses exploratory research to examine the relationship between the Organization's culture and the Effectiveness of the Performance Management System. The study uses a Structured Questionnaire to collect the primary data. For this study, Thirty-six non-clinical employees were selected from twelve randomly selected Health Care organizations at Thanjavur. Thirty-two fully completed questionnaires were received.
Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

By implementing talent management strategy, organizations would have the option to retain their skilled professionals while additionally working on their overall performance. It is the course of appropriately utilizing the ideal individuals, setting them up for future top positions, exploring and dealing with their performance, and holding them back from leaving the organization. It is employee performance that determines the success of every organization. The firm quickly obtains an upper hand over its rivals in the event that its employees having particular skills that cannot be duplicated by the competitors. Thus, firms are centred on creating successful talent management practices and processes to deal with the unique human resources. Firms are additionally endeavouring to keep their top/key staff since on the off chance that they leave; the whole store of information leaves the firm's hands. The study's objective was to determine the impact of talent management on organizational performance among the selected IT organizations in Chennai. The study recommends that talent management limitedly affects performance. On the off chance that this talent is appropriately management and implemented properly, organizations might benefit as much as possible from their maintained assets to support development and productivity, both monetarily and non-monetarily.
A STUDY OF VARIOUS TYPES OF LOANS OF SELECTED PUBLIC AND PRIVATE SECTOR BANKS...IAEME Publication
Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%. It shows the dark area of Indian banking sector.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
