Abstract:

This report presents experimental study on effect of partial replacement of coarse aggregate by Light weight coarse aggregate (LECA). LECA is also more or less similar to properties of coarse aggregate. LECA is used in concrete to minimize the demand of coarse aggregate and also in design of concrete structures, self-weight occupies very large portion of total load coming on the structures critically in cases such as weak soils and tall structures. Also impressive benefits in lessening density of concrete. And compare the weight of concrete and strength properties viz. cube compressive strength of light weight concrete against conventional concrete by partially replacing natural aggregates as LECA by 25% and 50%.As the percentage of LECA in concrete increases both slump values and compaction factor values are decreases at fresh concrete. As well as in hardened concrete density of concrete and compressive strength of concrete also decreases.
