Abstract:High weathering action in the corrosive and chemically active environment can significantly affect the strength characteristics of the concrete and also excessive utilization of sand as fine aggregates in building construction enhances degradation of the environment and urges the need for an alternative source in the scene of sustainable construction. Fly ash has generally used an alternative of cement, such as an admixture in concrete, and production of cement. As per the literature it has been found that concrete containing fly ash as partial to complete replacement of fine aggregate has been found to increase strength on a long-term basis. An experimental investigation was carried out to evaluate the strength and durability characteristics of concrete building blocks by replacing fine aggregates with fly ash at 10% to 100% by weight of fine aggregate and subjecting it to chloride attack and sulfate attack. Various tests were conducted for the properties of fresh concrete. Compressive strength and flexural strength were determined at 28 days. Test results indicate significant improvement in strength properties of plain concrete by the inclusion of fly ash as partial replacement of fine aggregate (sand), and increase in resistance to sulfate and Chloride attacks and can be effectively used in structural concrete.
