- Low Aggregate Sand In Malaysia
Fine aggregate, also known as sand, plays a crucial role in the manufacturing of concrete and mortar. One of the key properties of fine aggregate that affects its suitability for construction use is its specific gravity and water absorption. ... If the bulk specific gravity of the aggregates is too low, it may result in a weak and unstable ...
