TL;DR: In this paper, comments are made about indirect methods and direct Chapelle's method applied to the determination of the reactivity of pozzolanic materials and emphasized the expression of lime consumption per mass of the amorphous phase of these materials, as determined by X ray diffraction analysis with the Rietveld refinement method.

TL;DR: In this article, the impact from partial substitution of Portland cement for different contents of red mud collected in an alumina production plant in the northeast of Brazil was evaluated by isothermal conduction calorimetry and the Vicat test.

TL;DR: Of the three strains Pseudomonas putida INQCS 113 in modified B4 medium gave the best results precipitating 96% of the calcium, this strain thus has good potential for use on building materials.

TL;DR: In this article, the impact of the stoppage of the hydration reaction of CPV (cement Portland type V from Brazilian market) in the results obtained by freeze-drying or immersion in an organic solvent as isopropanol or acetone, followed by substitution for diethyl ether.

TL;DR: Six biocides were separately incorporated into the phosphogypsum at concentrations recommended by the suppliers and test specimens incubated on Sabouraud agar inoculated with various fungal isolates, and the biocide 2-N-octyl-4-isothiazolin-3-one was the most efficient compound.
