Salinity Concrete of Palm Ash

Abstract

This project studies the partial replacement of cement content in the concrete by the palm ash in the presence of seawater as a full replacement of pure water in mixing of the concrete. Certain percentages of replacement of the cement content with palm leaves ash are considered to investigate the behavior of both the strength and workability of the concrete. The slump test is carried out for the fresh concrete and the concrete strength is tested after 7 and 28 days. 5% of the cement replacement with palm leaves ash in conjunction with full replacement of pure water with sea water achieves 84.188% increase in the ultimate compressive strength after 28 days more than that gained by the normal concrete with the mixing sea water, also a reasonable workability is obtained.
