· The use of crushed limestone dust may affect the properties of concrete. As per Celik and Marar the inherent property of concrete to flow known as workability decreases with the use of crushed limestone dust. This is due to the presence of finer particles whose specific surface area is high, which absorbs more water and leads to a reduction in slump value.
