This document reviews the use of steel slag as an aggregate in asphalt road construction. It summarizes several studies that found replacing a portion of conventional aggregates with steel slag aggregates can improve the mechanical properties of asphalt concrete mixes. Specifically, replacing up to 75% of limestone coarse aggregate with steel slag aggregate was found to increase indirect tensile strength, resilient modulus, rutting resistance, fatigue life, and creep modulus of the mixes. Guidelines indicate steel slag can replace either fine or coarse aggregates in asphalt mixes but not both, to avoid issues like high void space. The conclusion is that use of steel slag in bituminous mixes can improve strength and stiffness while allowing thinner pavements without compromising stability or sk

Abstract The bituminous pavement rehabilitation alternatives are mainly overlaying, recycling and reconstruction. In the recycling process the material from deteriorated pavement, known as reclaimed asphalt pavement (RAP), is partially or fully reused and it is a valuable approach for technical, economical, and environmental reasons. Full Depth Reclamation (FDR) is one of the cold methods of recycling the bituminous pavements. In this study an experimental stretch is selected for FDR in which the full flexible pavement section and a predetermined portion of the underlying materials are milled and remixed with about 10 % of 10 mm down size aggregate and 30 % stone dust to match the Bituminous Concrete (BC) Grade-I mix limits and known quantity of RBI 81 stabilizer. Stabilization of RAP material with RBI grade 81 reduces the requirement of new materials, time of construction and increases the strength of the road. This report consist of a case study of road constructed at Jnanabharathi campus, Banglore University, which include assessment of existing pavement condition and the preparation of pavement surface for the construction of stabilized layer and construction aspects of pavement using RAP material stabilized with RBI grade 81. The report also presents results of some short term functional and structural condition studies on the study stretch. From the limited studies carried out it is concluded the RAP material can be used effectively by the stabilization with RBI grade 81. From the field studies it is concluded that the strength of the pavement increases with increase in RBI grade 81 dosages. Keywords: Stabilization of Reclaimed Asphalt Pavement (RAP), RBI Grade 81, Full Depth Reclamation, Cold in Place Recycling (CIR).

Abstract
Increase in environmental concerns has been leading to develop innovative and eco-friendly ideas to re-use the waste byproducts from
industries and domestic use. Waste plastic and waste tyres/crumb rubber considered as solid waste in India which causes
environmental pollution. These wastes will be disposed by land filling and incineration which are hazardous. Plastic is user friendly
but not eco-friendly. In this present study waste plastic and crumb rubber has been used to modify the conventional bituminous mix.
This modifier raw-material has been sourced from disposed waste plastic and crumb rubber. This provides a solution towards
ecological menace posed by increased use of plastic. Incorporation of waste plastic which is mainly consists of LDPE had been done
by “dry process”; an in-situ process which can be practiced locally. In this process addition of plastic has been done by replacing
bitumen by percentage by weight in varying percentage. Marshall Method of bituminous mix design was carried out. Significant
improvement in properties like Marshall Stability, retained stability, indirect tensile strength has been observed in waste plastic

Evaluation of Different Paving Mixes Using Optimum Stabilizing ContentYogeshIJTSRD
Bituminous mixes are most commonly used all over the world in flexible pavement construction. It consists of asphalt or bitumen used as a binder and mineral aggregate which are mixed together, laid down in layers and then compacted. Under normal circumstances, conventional bituminous pavements if designed and executed properly perform quite satisfactorily but the performance of bituminous mixes is very poor under various situations. Today’s asphaltic concrete pavements are expected to perform better as they are experiencing increased volume of traffic, increased loads and increased variations in daily or seasonal temperature over what has been experienced in the past. In addition, the performance of bituminous pavements is found to be very poor in moisture induced situations. Considering this a lot of work has been done on use of additives in bituminous mixtures and as well as on modification of bitumen. Research has indicated that the addition of polymers to asphalt binders helps to increase the interfacial cohesiveness of the bond between the aggregate and the binder which can enhance many properties of the asphalt pavements to help meet these increased demands. However, the additive that is to be used for modification of mix or binder should satisfy both the strength requirements as well as economical aspects.

To Study the Properties of Concrete with Partial Replacement of Aggregates wi...ijtsrd
Natural resources are depleting worldwide while at the same time the generated wastes from the industry are increasing substantially. The sustainable development for construction involves the use of nonconventional and innovative materials, and recycling of waste materials in order to compensate the lack of natural resources and to find alternative ways conserving the environment. So, this paper presents the results of an experimental investigation carried out to evaluate the mechanical properties of concrete mixtures in which fine aggregate sand was replaced with Copper Slag CS while coarse aggregates was replaced by recycled concrete aggregate RCA from demolished structure. Both the fine and coarse aggregate were replaced with percentages 0 for the control mixture , 10 , 20 , 30 , of Copper Slag by weight. Tests were performed for properties of fresh concrete and hardened Concrete. Slump test was conducted to determine the workability of the various design concrete mix. Compressive strength and split tensile strength were determined at 7, 28 days of curing. The results indicate that workability decreases slightly with increase in Copper Slag percentage, though workability for the sample were within the prescribed limit for M25 concrete. Test results indicate significant improvement in the strength properties of plain concrete by the inclusion of CS alone while a reverse trend in observed for increasing percentage of RCA in the sample. The synergistic effect of CS and RCA on the designed sample concrete revealed that the percentage of CS is the more decisive factors than the percentage of RCA in deciding the performance of the concrete in terms of compressive and tensile strength. The outcomes of this research work showed that Copper slag and recycled concrete aggregate can be effectively used in structural concrete as a replacement of fine aggregate sand and coarse aggregate respectively. Futher, it substantiate towards sustainable construction approach because of its dual advantage of controlling menace of solid waste disposal along with its subsequent environmental pollution and increasing the cost efficiency and carbon efficiency of the product.

Abstract This paper presents the results, obtained after replacement of fine and coarse aggregates, in concrete mix, with tyre rubber. The tyre rubber, which has been used in the present study, is obtained after the mechanical trituration process of post – consumed tyres from trucks. Researchers have investigated, over the years, the use of recycled tyre rubber waste as a replacement for aggregate in concrete and its effectiveness. “Rubcrete-Mix” which would result from such replacement is found to have many engineering applications and holds promise in future. Rubcrete also possesses good mechanical properties and is considered to be one of the best and economical ways of recycling the used tyres. The present experimental study has the aim of arriving at the optimum quantity of the replacement material for the aggregates in concrete mixtures, for various engineering applications. For achieving a proper bond with the surrounding concrete paste, the recycled aggregates have been designed with respect to their size, shape and gradation. With the water – cement ratio being kept constant fine and coarse aggregate has been replaced with tyre rubber powder and chipped rubber and also cement has been replaced with silica fume. In preparing the concrete, Portland slag cement has been used along with super plasticizer less than 1% by weight of cement to achieve required workability of the resulting concrete. Furthermore, durability studies have been conducted and mixes have been designed for M30 grade concrete. Keywords: Concrete Mix, Mechanical Properties, Rubber Powder, Chipped Rubber, Silica fume.

In India, total building waste is projected to be between 12 and 14 million tonnes per year, with concrete and brick trash accounting for 7 to 8 million tonnes. Concrete trash is generated in vast quantities during construction, demolition, and renovation. This trash is either disposed of in a landfill or diverted to one. This concrete waste can be recycled in a high quality manner. We offer the notion of sustainable use of concrete waste in concrete that can be utilised to make interlocking paver blocks in this study. After crushing, this concrete waste can be used as a total or half replacement for coarse and fine aggregates in paver blocks in two steps, according to IS.

Replacement of Natural Fine Aggregate With Air Cooled Blast Furnace Slag An I...IJERA Editor
The aim of the investigation is to replace natural fine aggregatewith Air Cooled Blast Furnace Slag in OPC concrete. At present, nearly million tons of slag is being produced in the steel plants, in India. The generation of slag would be dual problem in disposal difficulty and environmental pollution. Some strategies should be used to utilize the slag effectively. Considering physical properties of metallurgical slags and a series of possibilities for their use in the field of civil constructions, this report demonstrates the possibilities of using air cooled blast furnace slag as partial replacement of sand in concrete. A total of five concrete mixes, containing 0%, 12.5%, 25%, 37.5% and 50% partial replacement of regular sand with air cooled blast furnace slag are investigated in the laboratory. These mixes were tested to determine axial compressive strength, split tensile strength, and flexural strength for 7days, 28days, 56days and 90days.
Effect of Partial Replacement of Sand by Mild Steel Filings in Concreteijtsrd
Metals waste materials create serious environmental problems, mainly owing to the inconsistency of the waste streams. Mild steel filings are very small pieces of steel that look like a steel fiber. They are very often used in science demonstrations to show the direction of a magnetic field. The purpose of this project is to evaluate the possibility of using mild steel filings as one of the components of concrete mix. Five different percentage of mild steel filing were added to concrete mix to measure the variation which may be obtained in compression and tensile strength of concrete after 7 & 28 days. A number of standard cubes and cylinders were casted and tested in this study using 0% (control), 10%,15%, 20% and 25% of mild steel filing in concrete mix. Concrete cubes of size 150mm x150mm x 150mm and cylinders will be prepared and tested for compressive strength and tensile strength respectively after 7 and 28 days. A result data obtained has been analyzed and compared with a control specimen. Result data clearly shows percentage increase in 7 and 28 days compressive strength and flexural strength.

Mechanistic approach for reducing the thickness of asphalt layerAdhamAlnadish
This study aimed to evaluate the possibility of reducing the thickness of asphalt layer as a novel solution for the high density of asphalt layer incorporated with steel slag aggregate, which increase the cost of transportation. Mechanistic-Empirical Pavement Design (MEPDG) approach was employed to evaluate the benefits of introducing polyvinyl alcohol fiber in terms of reducing the thickness of asphalt layer as well as the extension service of asphalt layer. On the other hand, the correlation between creep strain slope (CSS) and secant creep stiffness modulus (SCSM) were assessed to provide a better evaluation and understanding concerning of the outputs of the dynamic creep test. The findings of this study showed that introducing polyvinyl alcohol fiber into the mixtures at the optimum content (0.5 kg/ton) have reduced the thickness of asphalt layer by approximately 10%. Additionally, polyvinyl alcohol fiber has increased the performance of the asphalt mixtures concerning of resilient modulus and dynamic creep. Furthermore, the correlation between CSS and SCSM was strong, which indicates that evaluation of permanent deformation using CSS and SCSM parameters provides better actual assessment than accumulation strain.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
