Abstract

A cement consists of ground cement clinker containing at least 50 per cent 3CaO.SiO2 mixed with a filler not so finely ground. At least 65 per cent of the clinker is ground to less than 20 m , while the filler, e.g. sand, is ground so that less than 10 per cent is larger than 0.2 mm. and not more than 20 per cent is smaller than 20 m . The cement and filler are ground separately and are mixed in the proportions of 80 - 85 per cent clinker to 20 - 50 per cent filler.
