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.
