Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass.

Limestone can be categorized as either high calcium or dolomitic. Pure high-calcium limestone is 100 percent calcium carbonate (100 percent calcite or aragonite). Generally, limestone of this purity does not occur naturally. High-quality, high-calcium limestone would actually contain 97 to 99 percent calcium carbonate and 1 to 3 percent impurities.

Cement is not mud and grass. You can make cement if you burn limestone in a fire until it glows incandescent. Let it cool and it will be brittle. You can pulverize it easily to a powder. This is quicklime and can burn you so be CAREFUL! KEEP DRY! It will create a lot of heat when rehydrated.
