To measure the degree of reaction of slag in blended pastes, five methods were studied. Selective dissolution and differential scanning calorimetry are shown to be unreliable, SEM-BSE-IA-mapping is time consuming, but does provide good results with a reaso ...
X-ray powder diffraction allows direct measurement of the phase content in cement. More recently, whole pattern approaches such as the Rietveld method show an improvement in both within (repeatability) and between laboratory (reproducibility) precision. Th ...
Production of cementitious materials causes the emission of CO2 gas, which has detrimental impact on the environment augmenting the global warming process. Using by-products such as slags is a possible strategy to limit the environmental impact of cementit ...
The applicability, reliability, and repeatability of Si-29 MAS NMR for determination of the quantities of alite (Ca3SiO5) and belite (Ca2SiO4) in anhydrous Portland cement was investigated in detail for 11 commercial Portland cements and the results compar ...
