A STUDY OF CONCRETE WITH BRICK-BALLAST AS COARSE AGGREGATE

Abstract

Dricl - baljaot forms a good auubotjtuto as a coarso agf rogate in taking the oonoroto,, rhon tho atone ballast or ;1rave is not aipajj 3blo at roasonab ,o cost and Dro nity. i djnzari y tho brick ballast is nothing but broltori piocoa of Vol burnt bricks of good quality0 Tho main factor such ao the unit oight crush Ong atron~gth 4nd absorption poor of coa oo aggroto twi t hatPO ' co aidorablo offoct on the overall strength and d'at'a° bility of concretoo RonOOD It bo00zos n000t3cary to tf,J as to chat o ant the concrete tado trcii bs etz - ballaot can ho used oconaoioally.
