The ARL 9900 Total Cement Analyzer provides fast process monitoring during the critical phases of cement manufacturing. It combines XRF analysis to determine the elemental composition of the material, and XRD analysis to provide mineralogical information about how the various elements are combined together to ensure the integrity of the final product.
Chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing. Producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete during mixing ...

Hydration products. The products of the reaction between cement and water are termed "hydration products." In concrete (or mortar or other cementitious materials) there are typically four main types: Calcium silicate hydrate: this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists' notation, to "C-S-H," the dashes indicating ...
Nov 01, 2004· In the Ca–Si–Al diagram, the chemical composition of the cement fraction inner products is quite different from that of the neat cement, having lower Ca and higher Si and Al contents. The outer products lay in a region bounded by the compositions of C–S–H, AFm and AFt.
When cement is mixed with water, the water replaces areas where there would normally be air. Because of that, the bulk density of cement is not very important. Cement has a varying range of density depending on the cement composition percentage. The density of cement may be anywhere from 62 to 78 pounds per cubic foot.
