After all, in a hardened Portland cement, some 60–70% of the sulphate normally ends up in the CSH phase, with little or no gypsum remaining. What is important here is the actual availablity of sulphate with the form of sulphate being very much a secondary issue in terms of thaumasite formation.

Stability and phase relations of dicalcium silicate hydrates under hydrothermal conditions
Included in this FREE, ready for download eBook is a summary on modern ideas having to do with the hardening and structureforming aspects of cement stone and concrete, the rheological and technological properties of concrete mixtures; and the strength, strain, and other properties that determine concrete operation, reliability, and durability.
Metakaolin (MK) je termički aktiviran aluminosilikatni materijal visoke pucolanske aktivnosti. Dodatkom matakaolina cementu poboljšava se kvalitet koji se manifestuje kroz: povećanje čvrstoće, skraćenje vremena vezivanja (da li je ova karakteristka prednost ili ne zavisi od primene cementa) sniženje autogenog skupljanja, kontrolu alkalnosilikatne reakcije, smanjenje rizika od ...

Lithium salts, known to ameliorate the effects of alkalisilica reaction, can make significant effects on cement setting. However, the mechanism of effects on cement hydration, especially the hydration of C3A which is critical for initial setting time of cement, is rarely reported.
It is an investigation of high magnesia portland cement, published in 60s 20th century.

Regarding the hot stage treatment, the combination of the chemistry modification with the addition of fly ash at 30 wt. % and fast cooling by means of water quenching resulted in a complete amorphisation of the material. Ultimately, the produced material possessing similar properties to granulated blast furnace slag could be used as a latent ...

Aspergillus infections have grown in importance in the last years. However, most of the studies have focused on Aspergillus fumigatus, the most prevalent species in the genus. In certain locales and hospitals, Aspergillus flavus is more common in air than A. fumigatus, for unclear reasons. After A. fumigatus, A. flavus is the second leading cause of invasive aspergillosis and it is the most ...
In order to gain a deeper understanding of the rheological development of hydrating ordinary Portland cement (OPC) pastes at initial state, and to better understand their underlying processes, quantitative Xray diffraction (XRD) analysis and rheological measurements were conducted and their results combined. The timedependent relation between phase development and flow behavior of cement ...
Laser ablation was investigated as a means of removing radioactive contaminants from the surface and nearsurface regions of concrete from nuclear facilities. We present the results of ablation tests on cement and concrete samples using a pulsed Nd:YAG laser with fiber optic beam delivery. The laser–surface interaction was studied on model systems consisting of type I Portland cement with ...
