Effect of Fine Aggregate Properties on Cement Mortar

2021-1-1  Fine aggregate being a main component in concrete production has a significant part to play in influencing concrete strength. Sand is commonly used as the standard material for a fine aggregate. Building and construction industries also contribute to environmental issues caused by the massive use of natural resources such as natural sand.
