Activated Clays and Their Potential in the Cement Industry

Autor: Rafael Talero Morales, Luiz Felipe de Pinho, César Pedrajas Nieto-Márquez, Carlos Hernando Aramburo Varela

The thermal activation of clays to produce highly reactive artificial pozzolans on a large scale is one of the most important technologies developed on an industrial scale to reduce CO2 emissions in cement manufacture. This technical document deals w
