Cement and Concrete Chemistry

TL;DR: In this article , the effects of mine waste and BaO on raw-mix and synthesized pure clinker phases in terms of burnability, ultra-features, chromaticity and mechanical strength of the synthesized clinkers were discussed through several techniques, including XRF, XRD coupled with Rietveld refinement, Thermal Analyses and SEM combined with EDS.

TL;DR: In this article, Cote et al. investigated the effect of the relargage of the chrome hexavalent in the production of ciment and found that it was negligeable.

TL;DR: Thermodynamic modelling of belite clinker mineralogy during manufacture successfully predicted the effect of alkali metals Na and K on the phase evolution of belite clinker. The results agreed with previous experimental studies and showed that alkali metals enhanced the C3S content and extended the temperature range of additional C2S formation on cooling.

TL;DR: In this paper, the effects of the sintering temperature on the pore evolution of the belite-sulfoaluminate cement clinker were evaluated, and a 3D microstructure reconstruction by micro-CT was used.

TL;DR: Fur die Praxis der Portland-Zement-Herstellung hat sich ergeben, das das gunstigste Verhaltnis von as mentioned in this paper, das bei uns (im Gegensatz zu England) die Berechnung des Moduls nur durch Division der Prozentzahlen, also ohne Berucksichtigung der Molekulargewichte, ublich ist.

TL;DR: In this paper, the authors present test results on the effect of different types of cements, age, humidity, and humidity on the strength of the Cascaded Carmel Loride attack.

TL;DR: In this article, the causes of several types of efflorescence on concrete and the steps that can be taken for prevention or removal are explained in simple terms and all the sections are also applicable to other materials incorporating portland cement, eg renderings, mortar, reconstituted stone and cement-based paint.
