  • Belterra clay could replace limestone in cement production

    2021-10-11 · At least 50-60 per cent of limestone can be replaced by Belterra clay, which provides several advantages when compared with limestone quarrying. The clay has to be removed anyway, so it does not have to be extracted only for cement production. Furthermore, the burning process only requires 1250˚C – 200˚C less than for Portland cement.
