A Comparative Study on Partial Replacement of Foundry Sand and Sea Sand as Fine Aggregate in Concrete

Concrete is the most popular building material in the world. River sand has been the most popular choice for the fine aggregate component of concrete in the past, but overuse of the material has led to environmental concerns, the depleting of securable river sand deposits and a concomitant price increase in the material. Therefore, it is desirable to partial replacement of Foundry sand and Sea sand obtain cheap, environmentally friendly substitutes for river sand in the concrete. Replacement of Foundry sand & sea sand instead of river sand as 0%, 20%, 30%, 60% and 100% respectively and  the strength parameters such as compressive strength and split tensile are analysed.
