Concrete sand consists of granite rock, gneiss, or limestone. This sand has angular granules and works best when mixed with cement. Besides usage in concrete, concrete sand can also be used in bedding pipes. This type of sand is usually crushed in a quarry and filtered severally to remove huge fragments and large rocks.

Limestone vs. Crushed Concrete. In its pure form, limestone differs significantly from crushed concrete in that the former constitutes a naturally formed rock found in marine environments and the other a manmade construction material. Limestone may appear in crushed concrete as a material found in the cement used to mix concrete.

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.
