TL;DR: In this paper, the roles of sodium hydroxide, calcium hydroxides and temperature on heat flow evolution and its relation to the reaction stages of alkali-activated coal fly ash were evaluated.

TL;DR: In this article, the synergy of the T1-C3S and β-C2S hydration reactions, across their mixtures in proportions of 70-30 and 30-70, has been studied through the quantification of the portlandite carried out by thermogravimetric analysis.

TL;DR: In this paper, the variation in ACI with particle size in three types of granite based on the chemical, mineralogical and radiological characterisation of five size fractions was analyzed. And the results showed that the activity concentrations of the thorium and uranium natural decay series were highest in the finest fractions.

TL;DR: The influence of sand nature on the burnability of white cement raw mixes manufactured using CaF2 and CaSO4 as flux and mineralizer has been studied in this article, where a methodology based on a statistical method called Experimental Design is used to establish a model.

TL;DR: In this article, an industrial cement obtained by milling together a new low energy clinker and gypsum, two blended cements containing 20% wt of fly ashes and 10% of limestone respectively, have been prepared.
