Jul 18, 2019 Posted on July 18, 2019. Concrete is a mixture of cement, gravel, sand, water and a range of aggregates. With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. It is also the world’s most widely used material for construction – from bridges to large buildings, concrete forms the very foundation of our infrastructure.
