Abstract
The Growth in the Electronics sector has been rapid and this rapid growth is due to continuous upgradation of technology and introduction of new technologies to the market. This has led to one of the fastest growing solid waste in the world, simply called as E-waste. India is the 5th highest e-waste producer in the world. The rapid increase in the construction activity in India, has resulted in huge demand for the aggregates to be used in the concrete. This has led to depletion of natural resources and adverse changes in the environment. This rapid development in the infrastructure sector has led to shortage of natural sand. This paper outlines the experimental work carried for utilisation of e-waste as a partial replacement for the fine aggregates. Strength tests and durability tests are conducted on hardened concrete. Results show that the partial use of E- waste as fine aggregates results in much higher workable and less dense concrete. This study gives an Economic, environment friendly and efficient disposal method for E-waste to be used as a partial replacement to the fine aggregates in concrete.

Experimental Study of Partial Replacement of Fine Aggregate with Waste Materi...IJRES Journal
The utilization of industrial and agricultural waste produced by industrial process has been the focus of waste reduction research for economical, environmental and technical reasons. This is because over 300 million tones of industrial waste are being produced per annual by agricultural and industrial process in India. The problem arising from continuous technological and industrial development is the disposal of waste material. If some of the waste materials are found suitable in concrete making not only cost of construction can be cut down, but also safe disposal of waste material can be achieved. The cement of high strength concrete is generally high which often leads to higher shrinkage and greater evaluation of neat of hydration besides increase in cost. A partial substitution of cement by an industrial waste is not only economical but also improves the properties of fresh and hardened concrete and enhance the durability characteristics besides the safe disposal of waste material thereby protecting the environment form pollution This paper deals with partial replacement of fine aggregate with the industrial waste from China Clay industries. The compressive strength, split tensile strength and flexural strength of conventional concrete and fine aggregate replaced concrete are compared and the results are tabulated.
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.
A research study of Donald u. Bulawin, Cristian Ralph E. Ibahay, and Mabeth L. Arellano. It is all about utilizing the waste bottle caps for concrete mixture. This study aims that by utilizing the waste bottle caps as a partial replacement for coarse aggregates helps in increasing the strength of concrete and in the environmental issues of wastes disposal.
Partial replacement of fine aggregrate and cement in paver blocks using waste...vivatechijri
A parametric experimental study for producing paving blocks using fine and coarse waste glass is
presented. Some of the physical and mechanical properties of paving blocks having various levels of fine glass
(FG) and coarse glass (CG) replacements with fine aggregate (FA) are investigated. The test results show that the
replacement of FG by FA at level of 20% by weight has a significant effect on the compressive strength, flexural
strength, splitting tensile strength and abrasion resistance of the paving blocks as compared with the control
sample because of pozolanic nature of FG. The compressive strength, flexural strength, splitting tensile strength
and abrasion resistance of the paving block samples in the FG replacement level of 20% are 69%, 90%, 47%
and15 % higher as compared with the control sample respectively.
Indian construction industry is growing at a rate of 9.2% as against the world average of 5.5%.
Construction by nature is not an eco-friendly activity. Construction, renovation and demolition activities lead to the formation of waste.
Growth in construction activities generates construction waste which is fast becoming a serious environmental problem with deadly
consequences. Most of the construction and demolition, waste in our country are not recycled but end up in landfills occupying valuable
land.
The promotion of environmental management and the mission of sustainable development have exerted the pressure demanding for
the adoption of proper methods to protect the environment across all industries including construction.
Construction waste recycling reduces the demand up on new resources. Cuts down the cost and effort of transport and production. Use
waste which would otherwise be lost to land fill sites.

Effect of Steel Slag as Partial Replacement of Cement on Property of Concreteijtsrd
A well maintained infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements is challenging. Concrete as a construction material is in use for several decades. Concrete can withstand the severest environments and engineers are constantly trying to improve its performance with the aid of modern admixtures and waste materials with or without cementious properties. The use of waste material in concrete helps to consume these waste materials and also improves the properties of concrete in fresh and hydrated states.Civil structures are designed considering the target compressive strength of the concrete. Although, few other parameters such as workability, water to cement ratio, setting time of cement and surface hardness influence the performance of concrete.In the present research a series of experiments had been performed to compare the use of Steel Slag as partial replacement of cement in different proportions. Concrete mixes are modified by 5 10 , 15 , 20 and 25 of Steel Slag as replacement of cement.The main conclusions drawn are inclusion of Steel Slag increases the compressive strength up to a certain proportion and then reduces the strength. Steel powder increases the strength but reduces the workability. Comparatively higher early strength gain 3 days, 14 days, 28 days is obtained with Steel Slag concrete.

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!

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
