Abstract

In this study, we have developed a new cement composed by a partial substitution of the clinker with artificial pozzolans rich in silica, obtained by treatment of lignocellulosic residues, in this case, ash from rice husk. This substitution is added to the clinker with percentages ranging from 25 to 75%. These substitutions were chosen on the basis of the presence of silica which can react with portlandite (Ca(OH)2).

The results obtained show that these materials have, after activation, a great pozzolanicity that allows their addition to the Portland clinker with a percentage of up to 25% of the mass of the clinker.

The improvement of this reactivity is achieved by calcinating these additions at temperatures of 750°C. This significantly reduces the CO2 emissions that accompany the production of Portland cement clinker.
