For hot desert climates, crushed concrete and limestone will work, while crushed stone or gravel plus aggregate road base is suited for snowy, cold areas.

Let's get this out of the way right here: cement and concrete are not the same thing. Cement, a mixture of powdered limestone and clay, is an ingredient in concrete along with water, sand, and gravel.

As Nina explains, concrete is created by combining water and aggregates with cement, a rock-like substance obtained by heating limestone with clay.

A building block in most construction projects, concrete is responsible for about 8 percent of global carbon emissions. Several companies are working to create a greener mix.

Royale Concrete found a well-preserved concrete substrate under 65 years of grime, then gave the slab a new life with an exposed aggregate polish.

Biomason’s biological production platforms produce concrete materials by combining aggregates (crushed rock and/or sand) with bacteria, nutrients, calcium and carbon sources.

Total Polish Solutions was brought in to finish what other subcontractors could not on 99,000 square feet of exposed aggregate polished and burnished concrete floors at the University of North ...

True, both plants rely on nearby deposits of easily accessible rock, but where cement requires limestone, the gravel and sand that go into concrete can come from a wide variety of rock types.
