Low-clinker cements

A forecast model for the carbonation of concrete

Producing concrete as a bulk construction material is associated with several significant environmental impacts, which are mainly attributable to the Portland cement clinker contained in the cement. This is why the development of concrete grades with low-clinker cements is currently being advanced. These concretes must be sufficiently durable in order to be used in construction practice. Any substitution of the clinker contained in the cement by ground admixtures such as blast-furnace slag, fly ash or limestone will usually reduce the carbonation resistance of the resulting concrete. For this...
