Recently, the use of crushed sand obtained from limestone-quarried is growing especially in the countries where river sand is not quite available. In the paper, the results from an experimental investigation are presented, which evaluates the pore structure of mortar mixtures where fine aggregate is replaced by Crushed Limestone Sand (CLS). The behavior of pore structure of CLS mortar was

The limestone sand used for this research has the density of 2.70 g/cm 3 and the density of mountain sand is 2.65 g/cm 3. According to Tarr and Farny , hard and dense aggregates reduce the shrinkage in concrete. As realized, there exists a small difference of the densities between fine aggregates of limestone and sand in the experiments. 3.5.

Crushed limestone has several important advantages over river gravel as an aggregate for concrete. First, for a given amount of cement in the mix, crushed limestone concrete will have an approximately 10% strength advantage. Additionally, crushed limestone concrete is easier to saw through than gravel concrete.

Recycling crushed concrete to be reused helps reduce landfill crowding AND saves more resources from being used to create new concrete. Old concrete can be crushed down to specific sizes, cleaned so that unwanted debris is removed from the mixture, and reused as a solution to a number of construction and landscaping problems.
