Experimental Investigation on Compressive Strength of LD Slag Aggregate Concrete

This paper aims to study the compressive strength of concrete made using Linz-Donawitz (LD) slag as a replacement for natural fine and coarse aggregate with both getting replaced up to 100% at an interval of 20% respectively. Concrete of grades M20, M25, M30, M35 and M40 has been considered for studying their compressive behaviour when natural aggregates are being gradually replaced with LD slag. The results obtain showed an increase in compressive strength of the concretes with the increase in percentage replacement of natural fine and coarse aggregates with LD slag.
