The use of crushed limestone dust may affect the properties of concrete. As per Celik and Marar [2] 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.
loss. Non-Darcy seepage properties of the crushed lime-stone are strongly influenced by compaction and particle size distribution. In general, during the compaction, the permeability decreases while the non-Darcy coefficient increases with the decreasing of effective porosity. The effective porosity, particle crushing and seepage properties

About Limestone. Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite or aragonite. It is a kind of stone widely found in nature. Limestone can be directly processed into stone using crushing equipment and fired into quicklime. Quicklime absorbs moisture or adds water to become hydrated lime.
