Effective Utilisation of Waste Glass in ConcreteIJERA Editor
Glass is a widely used product throughout the world; it is versatile, durable and reliable. The uses of glass
ranges drastically, therefore waste glass is discarded, stockpiled or land filled. About million tons of waste glass
is generated and around large percent of this glass is disposed of in landfills. This pattern has influenced
environmental organizations to pressure the professional community to lower the amount of glass being
discarded as well as find use to the non-recycled glass in new applications. In relation, the recycling of waste
glass as a component in concrete gives waste glass a sustainable alternative to land filling and therefore makes it
economically viable.The proposed study of utilising waste glass powder(GLP) in concrete as partial replacement
of cement as well as the use of crushed glass particles(CGP) retained on 1.18mm & 2.36mm IS sieve as a partial
replacement to sand, which offers important benefits related to strength of concrete as well as it is eco-friendly.
Recycling of mixed-colour waste glass possesses major problems for municipalities, and this problem can be
greatly eliminated by re-using waste glass as sand/cement replacement in concrete. Moreover, re-using waste
materials in construction can reduce the demand on the sources of primary materials.In this project the attempts
have been made to partially replace the cement as well as sand by waste glass powder and crushed glass
particles with equal combination by 5% interval up to 20% replacement and observe its effect on the strength of
concrete after 7 days and 28 days of curing.
Development of Green Paving Blocks Using Recycled Aggregates: An Approach tow...iosrjce
Present study deals with the laboratory investigations for fabrication of M-35 grade concrete paving
blocks using recycled coarse and fine aggregates as a replacement of natural aggregates from 25 to 100 % level
by weight and results were compared with control. It was observed that properties of recycled aggregates were
inferior to natural aggregates. However, the properties of recycled aggregates enhanced after washing. The test
results of blocks showed that the replacement of natural aggregates by recycled aggregates at the level of 25 %
had little effect on the compressive strength and it decreased beyond these levels. As compare to natural
aggregates, the flexural strength of paving blocks was higher using recycled aggregates. Durability
performance of blocks like water absorption, density and abrasion resistance was also improved using washed
recycled coarse aggregates. Petrographic image analysis showed improvement in the interface of washed
recycled coarse aggregates and surrounding matrix.

In this research work experiments have been conducted with collection of materials required and the data required for mix design are obtained by sieve analysis and specific gravity test. Sieve analysis is carried out from various fine aggregates (FA) and coarse aggregates (CA) samples and the sample which suits the requirement is selected. Specific gravity tests are carried out for fine and coarse aggregate. The various materials used were tested as per Indian standard specifications. On the basis of the experimental studies carried out on M30 grade concrete as partial replacement of coarse aggregates with sea shells and coconut shells, the following conclusions are drawn from the above experiment we conclude that comparing to traditional concrete, compressive strength of 10% (5% + 5%) of coconut shells (5%) and sea shells (5%) increased. whereas the compressive strength of the concrete cubes has gradually decreased from addition of 10% (5% + 5%) of coconut shells and sea shells. Hence for economical view 10% is preferable and in the perspective of compressive strength 10% is suggested. Thus, 10% replacement coconut shells and sea shells are recommended for both heavy weight and light weight concrete production.

Study of Macro level Properties of SCC using GGBS and Lime stone powderIJERD Editor
One of the major environmental concerns is the disposal of the waste materials and utilization of
industrial by products. Lime stone quarries will produce millions of tons waste dust powder every year. Having
considerable high degree of fineness in comparision to cement this material may be utilized as a partial
replacement to cement. For this purpose an experiment is conducted to investigate the possibility of using lime
stone powder in the production of SCC with combined use GGBS and how it affects the fresh and mechanical
properties of SCC. First SCC is made by replacing cement with GGBS in percentages like 10, 20, 30, 40, 50 and
by taking the optimum mix with GGBS lime stone powder is blended to mix in percentages like 5, 10, 15, 20 as
a partial replacement to cement. Test results shows that the SCC mix with combination of 30% GGBS and 15%
limestone powder gives maximum compressive strength and fresh properties are also in the limits prescribed by
the EFNARC.
Experimental study on Use of Waste Glass as admixture in ConcreteIJSRD
Glass is utilized as a part of numerous structures in everyday life. It has restricted life and after use it is either stock heaped or sent to landfills. Since glass is non-biodegradable, landfills don't give a situation well-disposed arrangement. Thus, there is solid need to use waste glasses. Many efforts has already been made in concrete engineering as a partial replacement of cement or fine aggregate or coarse aggregate. In this experiment we use waste glass powder as a partial replacement of cement and a comparative study has been made with other admixture such as fly ash and silica fume. A series of test were conducted with partial replacement of glass by 15% and 30% to weight of cement where as we have used only 15% of partial replacement in case of fly ash and silica fume just to compare the results with glass at 15% and 30%. The present study demonstrates that waste glass, if ground finer than 100µm demonstrates a pozzolanic conduct. It responds with lime at early time phase of hydration forming extra CSH gel along these lines shaping denser bond matrix. The early utilization of alkalis by glass particles moderate alkali silica reaction consequently expands durability of cement.

Abstract: The traditional Taguchi method is widely used for optimizing the process parameters of a single response problem. Optimization of a single response results the non-optimum values for remaining. But, the performance of a machining process is often evaluated by several quality responses. Under such circumstances, multi-characteristics response optimization may be the solution to optimize multi-responses simultaneously. In the present work, a multi-characteristics response optimization model based on Taguchi and Utility concept is used to optimize process parameters, such as magnetic flux, rotational speed of CFG rod, shape of CFG rod, number of cycles, abrasive-to-iron ratio and abrasive particle size on multiple performance characteristics, namely, surface roughness (Ra) and material removal (MR) during polishing of hollow cylindrical brass work-pieces with Centrifugal-Magnetic Force Assisted Abrasive Flow Machining (CMA2FM) Process. Taguchi’s L27 orthogonal array (OA) is selected for experimental planning. The ANOVA and F-tests are used to analyze the results. It is found that all the input parameters significantly improve the Utility function comprising of two quality characteristics (MR and %ΔRa). Further, the confirmation tests are conducted and the results are found to be within the confidence interval.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
