DEFINITION & CLASSIFICATION
Definition
A binder that sets, hardens, and adheres to other materials, binding them together.
The term "Cement" typically refers to hydraulic cement, which hardens when mixed with water
classification
Hydraulic Cement (Most Common)
Blended cements (e.g., Portland-Limestone, Pozzolanic): Mix OPC with supplementary Cementitious Materials (SCMs).
Portland cement (OPC): The standard, most widely used type. Forms cement by hydration reactions.
Non-Hydraulic cement
Hardens only in dry conditions or through reaction with gases (e.g., lime, gypsum plaster).
PORTLAND CEMENT (OPC) - COMPOSITION & PRODUCTION
raw materials (The ingredients)
Alumina Sources (Aluminum): Bauxite, Clay. (Provides A12O3)
Iron sources (iron): Iron ore, Mill scale. (Provides Fe2O3)
Silica Sources (Silicon): Clay, Sand, Shale. (Provides SiO2)+
lime sources (calcium): Limestone, Chalk, Shells. (provides CaO)
