Second, because crushed limestone has a lighter unit weight than gravel, it will require about 12% less crushed limestone than gravel to mix a cubic yard of concrete. Additionally, crushed limestone concrete is easier to saw through than gravel concrete. This is because most gravel is silica. Silica is almost impossible to cut with a steel saw.

Silica gel has a very strong affinity for water, which gives it an adsorption capacity of over 40% of its own weight at relative humidity. It is compatible with most materials except strong alkalis and hydrofluoric acid. It is resistant to most acidic streams and is therefore used in the drying or purification of acid vapors or liquids.
