Durability Studies on High-Strength Concrete Incorporating with Pumice Powder and Slag Sand

Abstract

The current scenario deals with the rapidly growing and emerging technology in the construction industry. The most important construction material for the construction work in the construction industry is concrete. Now a days, Concrete structures suffer serious deterioration under corrosive environment. Consequently, the safety of these concrete structures is decreased. To reduce this deterioration, the influence of Pumice powder (PP) and Slag sand (SS) as supplementing cementing materials of concrete is studied in this investigation.

The project mainly deals with the replacement of cement with Pumice powder and river sand with Slag sand. In this work, Pumicepowder used as partial replacement for cement in the range 10-50 % and river sand is replaced with slag sand with 100%.The grade of concrete proposed is M60.

Durability tests such as resistance to acid attack (H₂SO₄, HCL, MgSO₄) with 5% dilute acid solution will be used for exposure of 30 days, 60 days and 90 days and compressive strength of cubes will be tested. Weight loss due to acid exposure will also be tested.
