Diffraction investigations of cement clinker and tricalcium silicate using Rietveld analysis
Cement is the world's most popular building material, yet surprisingly its composition is not fully understood. Due to the complex nature of cement constituents, there is currently no reliable method to quantitatively determine the composition of cement. Partly this arises from the fact that the …
