Due to the increase of world population shortage of lands are measure problem for civil engineering to manage all the
facilities requirements of peoples. So it is necessary to make high-rise building as well as skyscrapers. For this kind of highrise building dead load is too large and measure difficulties building and other structures. To solve this problem it is
necessary to reduced weight of concrete by adding lightweight aggregate.
For present study we have chosen ‘sintagg’ sintered type of lightweight aggregate and perform test on it like Bulk density,
Specific gravity, Water absorption etc and compare test result with normal aggregate. We have design M20 grade of normal
concrete and replacing natural aggregate with lightweight aggregate by proportion of 10%, 30%, 60% and 100%
respectively. Then compare weight and compressive strength of normal concrete blocks and lightweight aggregate concrete
(LWAC) blocks after 7 days, 14 days and 21 days of curing by graph.
