Conversion of Red Muds into Pozzolans [PDF]
Red muds are waste materials obtained from the aluminium extraction industry. They consist mainly of clays, aluminium and iron hydrated oxides. Three muds were studied; they differed in chemical and mineralogical compositions.

Pozolanicidade do resíduo cerâmico
The construction industry is still responsible for generating a significant volume of waste from mortars, concrete and ceramic materials. We underline in this scenario the residue of ceramic bricks that can be used in the production of new materials ...

Bentonite Clays from Southeastern Spain as Sustainable Natural Materials for the Improvement of Cements, Mortars and Concretes [PDF]
The effects of global climate change are becoming more evident and accelerating at an unprecedented pace. For this reason, human activities urgently need a paradigm shift to stop this entropic process before the consequences become irreversible.

Evaluation of Rice Straw Ash as a Pozzolanic Addition in Cementitious Mixtures
Rice husk ash is one of the most widely studied biomass ashes used in pozzolanic addition. Given its lower silica content, rice straw ash (RSA) has been explored less often, despite the fact that, according to the United Nations Food and Agriculture ...

Heats of hydration and pozzolan content of portland-pozzolan cements
Methods are described for the measurement of the approximate heat of solution in acid of portland-cement^-pozzolan mixtures. Examples are given of the estimation of the heat of hydration of portland-pozz olan cements. Determinations of the amount of material undissolved in the calorimeter, as well as the heats of solution, were applied to the problem ...

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