Csa rietveld amorphous paste
WebSix ordinary Portland cement (OPC) clinkers and one white cement clinker were analyzed with the Rietveld method, using ZnO internal standard (IC), to determine the presence of amorphous matter (AM). All clinkers contain abundant AM and have lower silicate phase contents when compared with the same clinkers analyzed without IC, whereas the … WebRQPA in OPCs can be used for a number of applications including (i) quantification of the crystalline phases in OPCs, (ii) to analyse the amount and role of sulfate-containing phases, (iii) to study the mineralogical phase assemblage in the materials used as addition (s) and (iv) to quantify all phases in blended OPCs, including the …
