Effects of the secondary minerals of the natural pozzolans on their pozzolanic activity

Cement and Concrete Research, 2008
Abstract Natural pozzolans have been widely used as substitutes for Portland cement, because of their binding properties. Some of them are natural volcanic rocks which contain secondary minerals such as clays and zeolites corresponding to products of the alteration of the rock.

Assessment of the pozzolanic reactivity of aggregate washing fines for use in Cement-Based Materials

Developments in the Built Environment
This study focuses on the valorization of fines from aggregate washing (AWF), an industrial residue with a high clay mineral content, as a pozzolanic alternative to additions in cementitious binders. The Fines, were subjected to thermal activation at 750
