摘要

Belite cement clinker containing e.g. fly ash of high-lime coal consists of in the main dicalcium silicate low-temperature alpha phase containing e.g. iron, aluminum, magnesium, sodium and potassium to enhance reactivity. Hydration of 100 per cent clinker cement minimizes calcium hydroxide formation with corresponding increase in the resistance of the cement to aggressive media. Accelerated curing of the cement mortar at e.g. 40 [deg] C with addition of water demand reducers gives mechanical strength equivalent to conventional Portland cement.
