| Cement is a finely ground powder of burned limestone. It reacts readily with water (hydrates) to form a solid material, known as hardened cement paste. When cement is mixed together with rock aggregate, sand and filler materials, it forms concrete. Cement is one of the most important base materials in general use in the construction industry. The optimisation of concrete with respect to frost resistance, durability, chemical resistance etc. is of great importance. |
