Ordinary Portland cement is the most widely used type of cement globally, with over 1.5 billion tons produced annually. It is manufactured through a wet or dry process involving crushing and mixing limestone and clay, heating the mixture in a rotary kiln to form clinker, grinding the clinker with gypsum. When mixed with water, it …

CHEMICAL COMPOSITION OF P.C. • Portland cement is composed of four major oxides (CaO, SiO2, Al2O3, Fe2O3 ≥90%) & some minor oxides. Minor refers to the quantity not importance. CaO→limestone • SiO2-Al2O3→Clay • Fe2O3→Impurity in Clays • SO3→from gypsum→not from the clinker.
Minimum values of compressive strength in ASTM C150. Cement • Water-Cement Ratio: (Abrams 1918) w/c affects the concrete quality (strength and other desirable properties). Hydration requires 0.22 – 0.25 kg water per 1 kg cement. Concrete require excess moisture, beyond hydration, for workability. As w/c increases.
It is a significant structural building material. Raw materials for cement creation are limestone, sand or clay, bauxite, and iron mineral, and may incorporate sheets, chalk, marl, shale, clay additionally impact blast furnace slag. Chemical analysis of cement raw materials gave knowledge into the substance properties of cement.
