Concrete plays a vital part in our daily lives, through many diverse applications and usages. It is, in fact, the most used man-made material in the world, with three tons used annually for each man, woman and child.
Thanks to its properties (strength, durability, thermal mass, affordability and abundance of raw materials), concrete can enhance the sustainability of the built environment (from schools, hospitals and housing, to roads, bridges, tunnels, runways, dams and sewage systems), as it offers wide flexibility to construction professionals to achieve their sustainability goals.
Cement is the essential “glue” in concrete. It reacts with water to bind aggregates (crushed stone and gravel) and sand.
