Portland cement consists essentially of compounds of lime ( calcium oxide, CaO) mixed with silica (silicon dioxide, SiO 2) and alumina (aluminum oxide, Al 2 O 3 ). The lime is obtained from a calcareous (lime-containing) raw material, and the other oxides are derived from an argillaceous (clayey) material.

06.11.2020It takes two ingredients to make cement in the wild – mud and grass. To begin, find a source of mud that is high in clay content. Mud with high clay content will ball up in your hand and retain its shape when released. The higher the clay content the better the quality of the hardened cement. Next, harvest grass, preferably dry grass.
