Ramlochan – Early Age Reactions of Sulphate Phases that Conribute to Early Stiiffening of Hydraulic Cements
Terry Ramlochan
X-ray diffraction studies using Rietveld analysis were performed to investigate how the various alkali/calcium sulphate phases in Portland cements contribute to early stiffening. XRD analyses were done both prior to hydration and within minutes after mixing to see what mineralogical changes occur during the first few minutes of hydration.
