Almost any mineral can be used in a cement rawmix, provided that the bulk composition of the mixture will produce the desired calcium silicates and fluxes (see clinker), and provided that certain deleterious components are minimized. Broadly speaking, minerals.

Use of raw materials in the cement industry - VDZ

In 2015, the German cement industry procured around 41 million tonnes of primary raw materials (see table). Furthermore, approx. 8 million tonnes of alternative raw materials were used to manufacture approx. 31.2 million tonnes of cement. In taking this measure, the German cement industry is making a valuable.

CEMBUREAU - Raw material substitution

The main raw material used in cement production has traditionally been line. Line is abundantly available, but over 60% of the industry's CO2 emissions are caused by transformation of line into lime, called “decarbonation”. Accordingly, part of the route towards a low carbon concrete-built environment can.
