Portland cement, the most common of modern cement, is made by carefully blending selected raw materials to produce a finished material meeting the requirements of ASTM C150 for one of eight specific cement types. Four major compounds [lime (CaO), iron (Fe2O3), silica (SiO2), and alumina (Al2O3)] and two minor compounds [gypsum (CaSO4 2H2O) and magnesia (MgO)] constitute the raw materials. The calcareous (CaO) materials typically come from limestone, calcite, marl, or shale.

The properties of stone depend on what nature has provided. Therefore, the designer does not have the choice of properties and colors available in some of the manufactured building units.
What is a sustainable building? For your building to be sustainable, many factors need to be considered. These include air quality, energy
