Ordinary Portland Cement (OPC) forms the backbone of modern construction, but for complex, demanding environments, specialty and advanced cements are engineered to provide superior properties such as enhanced durability, rapid strength development, chemical resistance, and sustainability. Learn about raw materials of cement.
Quiz:
(FAQ)
Q1: Which cement is best for marine construction?
Sulphate Resisting Cement is ideal because it prevents ettringite formation and resists seawater sulphates.
Q2: Is Geopolymer cement commercially available everywhere?
Not yet. Availability is limited, but demand is rising in sustainable projects worldwide.
Q3: Can white cement replace OPC in structural works?
White cement has similar chemistry but is costly. It’s mainly used for decorative and architectural purposes.
