Determining the percentage of blended cement content in soil cement mixture using powder x-ray diffraction

Soil cement mixture is one of the most economically feasible materials used for the construction of roads, pavements, diaphragm walls. The percentage of cement or blended cement in soil cement mixture plays a key role in improving soil's physical and chemical properties. . There have been some previously established techniques to analyse cement in a composite mixture: wet chemical analysis, spectroscopic analysis and particle size analysis. Some of the aforementioned could be onerous in terms of sample and standard preparation. In this research, we have adapted X-ray diffraction to calculate the percentages of cement contents (between 5 and 15%) in any soil cement mixture. In this paper, we have described the steps involved to calculate percentage of cement and blended cement in a soil cement mixture from X-ray diffraction spectra.
