Crushed Limestone Concrete Aggregate | Texas …

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. This strength advantage comes from the fact that cement bonds tighter to limestone than to a slick/smooth gravel and the strength that is derived from the sharp angular ...
