Experimental Study on Strength Properties of Concrete using Brick Aggregates

Abstract

Concrete has captured almost entire construction industry and its ingredients such as cement, manufacture of
cement and bricks consume large quantities of natural resources and fuel with C0 2 to the green house gases resulting in
global warming. Therefore, under such critical scenario of shrinkage of natural aggregates resource and ever increasing
pressure to reduce construction costs and further construction & dismantling of old structure producing heavy debris
needing disposal has made it necessary to invert, discover & think of other alternatives for replacement of coarse
aggregate.
The present paper aims with the study of strength properties of concrete using brick aggregates. To use over-burnt
bricks, normal burnt brick as replacement to conventional normal aggregate in different proportions. Brick aggregates
can fully or partly replace the conventional coarse aggregate to produce M20 concrete. M20 grade concrete mix with
different proportions i.e. [1:1.5:1, 1:1.5:2, 1:1.5:3] are carried out using over-burnt, normal burnt brick aggregates.
Physical proportions of cement, fine aggregate & normal aggregate, normal burnt brick aggregates, over-burnt brick
aggregates are carried out. Cube compressive strength test & split tensile test are carried out for 7 & 28 days. An
attempt has been made using brick aggregate concrete to replace normal aggregate concrete
