Effect of rolled aggregate powder on mechanical strength and durability of mortars exposed to acid attack

Abstract

This paper outlines an investigation into the effect of incorporating rolled aggregate powder as a cement replacement on mortar mechanical strength  and resistance against sulfuric acid attack. The study examined compressive strength, and mass loss changes of mortars based on 10, 20 and 30% rolled  aggregate powder replacement rates immersed in fresh water and 12 weeks in 5% sulfuric acid solutions. Experimental results showed improved  compressive strength, with 10 and 20% rolled aggregate powder replacement rates and enhance mortar resistance to aggressive sulfuric acid attack.
