When we look all around us we see huge buildings, little houses, bridges, sidewalks, roads, walls, offices etc. how often do we stop to think how these came about? They have not always been there, they evolved with mankind. There was a time when clay had to be baked in ovens made especially for this purpose. Bricks made like this were in vogue even in the ancient Egypt. Nowadays the construction scene has changed tremendously. A landmark in the construction industry came with cement mixers. Today we take the cement mixers that we see in construction sites for granted but this was not always so. Long time ago, the Greeks mixed asphalt with water and other things to get a substance which when hardened became ideal for construction. This concrete like material was named "cement", which in Greek means "secure".
