Portland cement is the most common type of cement in general use around the world, used as a basic ingredient of concrete, mortar, stucco, and most non-speciality grout. It was developed from other types of hydraulic lime in England in the mid 19th century and usually originates from limestone. It is a fine powder produced by heating materials in a kiln to form what is called clinker, grinding the clinker, and adding small amounts of other materials. Several types of Portland cement are available with the most common being called ordinary Portland cement (OPC) which is grey in color, but a white Portland cement is also available.

Ever since the Romans used palm fronds and other plant fiber matting to reinforce the sub-bases of their famous roads, fabrics have been used to improve road longevity and performance. Modern road construction methods rely on a family of materials called geosynthetics to achieve the same results. But these more sophisticated materials can
