Crushed Stone Vs. Gravel and How Gravel Suppliers Can

Sandstone. Composed mostly of quartz, sandstone is a durable material. However, it does have its drawbacks. Sandstone naturally forms from sand grains that have been cemented together by clay, calcite, or silicate minerals. But since this natural cement doesn’t fill all the voids between the sand grains, sandstone

The Complete Guide to Crushed Stone and Gravel

2019-11-11  Crushed stone: If you hear the generic “crushed stone” term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.
