EFFECT ON COMPRESSIVE STRENGTH OF CONCRETE WITH ADDITION OF SOLID WASTE ASH

Abstract

The availability of raw material is very limited due to the increased use of concrete. The standard practice of concreting is dosing, mixing (all raw materials), transportation, on-site compaction, finishing and hardening of all raw materials are done industrially. In developed countries like India, the amount of concrete is more and the availability of raw materials is very limited. A complete replacement of concrete is not possible, because no material can fulfil the role of concrete in terms of strength, durability and workability. To achieve the desired workability, strength and durability of concrete, the entire material must be partially replaced. This article provides an explanation of solid waste ash materials used in concrete. The test procedure involved preparing concrete samples with a percentage of cement replaced by fly ash (0%, 5%, 10% and 15%) and evaluating their compressive strength (7 and 28 days) and split tensile strength after 28 days of curing.
