Entry of SO3 into the structure of dicalcium silicate

Popis výsledku v původním jazyce

Dicalcium silicate containing foreign ions (Ca2SiO4 ? C2S) occurs as a component of Portland cement clinker and is called belite. Belite has lower hydraulic activity than alite (contaminated tricalcium silicate), which is the main component of Portland cement clinker. Belite can be prepared with lower expenditures and its hydraulic activation can have important impact on the economy and sustainability of cement industry. Our research is focused on the activation of C2S by incorporation of SO3 into its crystal structure. Experiments with pure chemicals have shown that S substitutes Si, stabilizing thus monoclinic ?-belite. Maximum content of SO3 in C2S was observed in our sandwich experiments; it amounts (under normal burning conditions) to 4.4 wt. %. HU ISSN 0324-6523
