Concrete Construction
The word “concrete” has its origin from the Latin word “concretus”, which means to grow together. It is a very strong and versatile construction material as it can be moulded to take up the shapes required for the various structural forms. It is produced by mixing cement, sand, and aggregate (e.g. gravel or crushed rock) with water. The oldest concrete was discovered around 7000 BC. It was found in 1985 when a concrete
floor was uncovered during the construction of a road at Yiftah El in Galilee, Israel. It consisted of a lime concrete, made from burning limestone to produce quicklime, which when mixed with water and stone hardened to form concrete [1].
