Abstract

The invention concerns a cement matrix and its advantageous production, in particular for glass-fibre reinforced cement or concrete, consisting of a standard or special cement and additives in a solid or liquid form for binding the calcium hydroxide which forms during the hydration process. A particularly advantageous additive is reactive silicon dioxide which is recovered from the flue gases during the production of silicon or ferro-silicon, whereby the silicon dioxide is first reduced and the reduction product is then oxidized in air. The total quantity of additives must be at least equivalent to the required quantity needed, in order to bind the total calcium hydroxide produced during hydration or cause a reaction. The other additives, apart from reactive silicon dioxide, are metakaolin, diatomaceous earth, pozzolana, blast furnace slag and fly ash or a combination thereof.
