This paper discusses about a very simple lab experiment of light weight concrete making. A concrete cube is prepared by using sand, cement, water, over burnt brick bats & fly ash. Fly ash is used as a cement replacement and over burnt brick bat is used as a coarse aggregate. Both fly ash & over burnt brick bats are considered as waste materials of thermal power plant & construction sites. Mix design is done for M20 grade of concrete As per IS 10262-2009. Finally it was seen that 16.67% reduction of weight without increase the cost. It was also seen that for M20 grade of concrete it provides 94.9% strength at 28 days compression test. This is quite significant & this ordinary mix design also gives satisfactory performance of lightweight concrete cube making.
