Compared to the mining of limestone where only < 10% of removed material is a waste, the mining of industrial grade clay for calcination can produce on average 20–50% waste; in fact, the mining of industrial kaolin can produce up to 90% waste, but these residuals can in fact be partly used as calcined clay SCMs Nonetheless, the amount of ...
The major innovation presented here is the possibility to make a coupled substitution of cement with calcined clay and limestone. This allows much higher levels of substitution. Blends where calcined clay is used as a pozzolan, typically have clinker contents around 65–70%. Combination of calcined clay with limestone allows higher …
