The effects of limestone aggregate on concrete properties .

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.
