Concrete is a widely used structural material with applications ranging from simple elements such as fence posts and railway sleepers to major structures such as bridges, offshore oil production platforms and high-rise buildings. In essence the material is a conglomerate of chemically inert aggregates (i.e. natural sands, crushed rock etc.) bonded together by a matrix of mineral cement. The aggregates and cement are mixed together with water to create an amorphous, plastic mass, i.e. concrete. A chemical reaction between the cement and the water, known as the hydration process causes the cement to harden and the conglomerate to gain strength over a period of time.
