Concrete

Concrete is a mixture of aggregates (approx. 80%), cement (approx. 12%), and water. Depending on the desired application, the characteristics of the concrete can be changed through the use of certain additives.

Except for water, no other substance on the planet is used more than concrete. All major construction projects – whether for tunnels or bridges, office buildings or schools – use concrete in some form or another. Concrete is usually delivered to the building site by ready-mix trucks and is poured locally into forms. Moreover, concrete is also used for the production of precast concrete parts, such as stairs, ceiling elements, or structural components.
