An experimental investigation on concrete with e waste fr4 As fine aggregate for enhanced thermal and acoustical properties

Abstract

The worldwide challenge faced today is that of handling waste. newlineThis issue of waste disposal is so crucial that the ill effects are newlineconspicuously visible everywhere. Diseases unheard of, disturbances in newlinethe ecological balance, natural calamities etc. are taking a toll on life in newlinethe planet. On top of this comes the problems associated with exponential newlineinfrastructure and information technology development. Each one has its newlineown share of boons and banes. One such matter to be dealt with is the newlinerapid depletion of natural resources and thereby scarcity of construction newlinematerials. newlineAs far as the civil engineering field is concerned, social newlineresponsibility comes as of key importance. This research study is taken newlineup keeping all these factors under consideration. Utilisation of a newlinehazardous waste product like E-waste or electronic waste is done by newlineincorporating it as a replacement for another sparse material- river sand. newlineThe type of E-waste selected here is that of Printed Circuit Boards (Flame newlineRetardant category). This is prepared and powdered for use as fine newlineaggregate. Partial replacement is carried out in various percentages. newlineScrutiny of previous literature studies is done to narrow down the area newlineand scheme of the present research. newlineStudies are conducted on concrete using E-waste for material newlineproperties, mechanical characteristics, durability properties, acoustic newlineproperties and thermal characteristics on M30 concrete. Quality control newlinetests like those of Ultrasonic pulse velocity determination are also newlinevi newlineconducted. Rebound hammer test is another strength assessment test newlinedone. Optimum replacement percentage is identified. newlineBased on the results obtained from the different experimental newlineinvestigations, a feasible solution for utilization of E-waste as fine newlineaggregate is proposed in this research study. This is expected to contribute newlineto the solution for two major problems; one - that of E-waste disposal and newlinethe other of river sand scarcity newline
