Apr 05, 2020 Cement. Ancient Romans were probably the first to use concrete – a word of Latin origin – based on hydraulic cement that is a material which hardens under water. This property and the related property of not undergoing chemical change by water in later life are most important and have contributed to the widespread use of concrete as a building material.
The exact composition of slag varies over a range. In general, factors that determine the suitability of slag for usage in composite cement mainly include the fineness of grinding, glass content and the chemical composition. Fineness Like most of other cement materials, the reactivity of slag is influenced by its surface area.

Aug 23, 2017 Cement composition. In the dry process of cement, the raw materials are crushed in the absence of water and put them into grinding mill with correct proportions, the proportion can be determined based on the purity and composition of raw materials. Hydration is the chemical reaction between cement and water and aggregate unless it is.
The chemical composition of cement has little effect on the rheological properties of concrete. Also, keep in mind mill certificates represent about a month’s average of tests at the cement mill. An even better indicator, perhaps, of your cement’s performance is an ASTM C917, “Standard Test Method for Evaluation of Variability of.
