Cement production with pozzolans from residual tropical soils formed from paragneiss with a high silicon oxide content

Dyna, 2020
The manufacture of cement demands a lot of energy and gives off large amounts of CO2. Calcined clays need less energy and emit water instead of CO2, which has drawn attention to them, especially those rich in kaolinite.
