STUDY ON MECHANICAL PROPERTIES OF LIGHT WEIGHT CONCRETE USING CINDER

Abstract

Light weight concrete plays a major role in reducing the density and increase the thermal insulation. More environmental and economical benefits can be achieved if waste materials can be used to replace natural aggregate.. In this study, an attempt has been made to study the Mechanical Properties of a structural grade light weight concrete M25 using the light weight aggregate cinder as a partial replacement to coarse aggregate in various percentages like 0%, 10%, 20%, 40%, 60%, 80% and 100% by volume of natural aggregate  and fly ash as a partial replacement to cement in various percentages like 15%, 20% & 25% by weight of cement.. The main function of using cinder material is to minimize the cost and to reduce the disposal of waste material and to reduce the dead load. From the study it is concluded that the compressive strength, split tensile strength and density are decreased continuously with the increasing the percentage of cinder aggregate. The optimum (15%) replacement of cement with fly ash gives better results. The optimum (60%) replacement of coarse aggregate with cinder provides good strength results. Therefore, the light weight concrete is no way inferior for construction purpose.
