What is type 5 cement?
Type 5 cement, formally classified under ASTM C150 as sulfate-resistant portland cement, is a specialized hydraulic cement designed to withstand severe chemical environments where concrete structures are exposed to high concentrations of sulfates. This type of cement restricts the tricalcium aluminate content within its chemical makeup to minimize destructive expansion, cracking, and deterioration caused by sulfate attacks from alkaline soils, industrial wastewater, or seawater. It is frequently specified for underground construction, marine foundations, coastal retaining walls, and drainage structures requiring long-term durability in aggressive ground conditions.
