The 42,5R cement can produce the same high strength concrete as the 52.5N strength class cement, due to it having similar 2day and 28day strength requirement as 52,5N cements. With so many different cement products on the market, what would a cement with the following specification CEM II / B-M (V-S)32,5N actually mean?

In addition to the resistance to sulphates, one of its advantages is that the clinker from which we produce this cement does not contain any tricalcium aluminate.

The strength development of a cement is not only defined by the composition but also by the grinding fineness, divided into classes (32.5 - 42.5 - 52.5).. This classification takes place based on a pressure test after 28 days. Within each strength class the performances define from an early stage the distinction between the 'Normal' (N) and 'Rapid' (R) version.
