Effect of Partial Replacement of Cement with Volcanic Ash on Mechanical Behaviour of Mortar
Portland Composite Cement (PCC) has so far been the most used binding material worldwide. However, it is also one of the significant sources of carbon dioxide emitters leading to global warming. It is, therefore, of utmost importance nowadays in developing nations that a sustainable cementitious material is developed. Volcanic ash (VA) is the debris found after volcanic eruptions. VA shows pozzolanic properties upon reacting with calcium hydroxide, which is given off during cement hydration. This paper represents the effect of VA on the physical and mechanical properties of mortar. VA is used to replace PCC by 5, 10, 15 and 20% by weight. The results of the mechanical properties are represented in terms of compressive strength, whereas the physical properties are illustrated through its specific gravity, fineness, setting time and consistency. This study shows that the compressive strength of the hardened mortar increases as the replacement is increased up to 15% by weight and then decreases as the replacement with VA is greater. Lastly, this study suggests the potential of VA as a partial substitute for cement to fabricate green concrete structures.
