How Cement Is Made

Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with ...

Natural building materials - Centre for Alternative Technology

Most natural building materials are breathable, and you'll need to ensure you don't seal them up behind finishes that will trap moisture. One example is using lime plasters and renders. Unlike cement, lime is breathable and so is a sympathetic finish or binder for natural materials.

Pozzolan - Wikipedia

Both natural and artificial (man-made) materials show pozzolanic activity and are used as supplementary cementitious materials. Artificial pozzolans can be produced deliberately, for instance by thermal activation of kaolin-clays to obtain metakaolin, or can be obtained as waste or by-products from high-temperature process such as fly ashes from coal-fired electricity production.
