Concrete is a carefully balanced mix of cement, aggregates and water. Cement acts as the binder and modifies the characteristics and uses of concrete:
- Portland cement is used to make reinforced concrete,
- blended Portland cement is used for slabs and roads,
- other types of cement are usually reserved for work that does not require particularly high resistance to heat.
Aggregates, another essential ingredient in concrete, retain the intrinsic properties of the rocks that they come from. The color and chemical and physical characteristics of aggregates have a direct impact on the durability, esthetics and mechanical properties of concrete.
