Steam-cured bricks mainly rely on the effective CaO in quicklime and SiO2 in fly ash to initiate a thermal synthesis reaction under the condition of saturated steam (above 174.5°C) with a pressure above 0.8Mpa. Various types of silicate gelling substances are produced, most of which are calcium silicate hydrate and a small amount of magnesium silicate, etc., which are firmly cemented with aggregate fly ash to form a certain structural strength. Its reaction process:
CaO+H2O—Ca(OH)2+15.5 kcal (mixed with body expansion)
Ca(OH) 2+ SiO2+(n-1)H2O Saturated steam at 174.5°C CaO*SiO2*nH2O (calcium silicate)
