Light weight concrete has become more popular in recent years owing to the tremendous advantages it offers over the conventional concrete. The main specialties of light weight concrete are its low density and thermal conductivity. It's advantages are that there is a reduction of Dead load , Faster building rates in construction and lower haulage and handling costs. We are replacing the cinder instead of coarse aggregate; it is obtained from steel industries. The surface of the cinder is usually rough and high porous due to mineral structures. Low specific gravity of cinder in compression with natural aggregates resulted in the concrete made with cinder to be lighter than normal concrete. Based on the literature, the main function for usage cinder material is to minimize the cost and it is reduced to disposal of waste material and it helps in reduction of Dead load. An experimentally has been conducted on concrete with partial replacement of conventional coarse aggregate by another light weight aggregate. The M20 concrete mix is designed using ISI method. In current investigation, the replacementof coarse aggregates with cinder of varying percentages of 0,25,40,60,75,100 and cement is replaced with silica fume of percentages like 5, 10, 15,20%and fly ash with varying percentages of 10,20,30,40 and determine the mechanical properties like compressive strength and split tensile strength subjected to 28 days curing.
