Cement
ATZ PORTLAND CEMENT TYPE II C150 is made from high-quality clinker finely ground with gypsum, this cement offers moderate sulfate resistance and rapid strength gain. Ideal for projects needing excellent short- and long-term performance under mild sulfate conditions.
Applications:
ATZ PORTLAND CEMENT TYPE II C150 is suitable for concrete, mortar, plaster, and bricks, it excels in projects needing moderate sulfate resistance, such as foundations in sulfate soils, paving, and marine structures. It provides excellent workability, durability, and early strength for general construction in mildly aggressive environments.
Specifications:
ATZ PORTLAND CEMENT TYPE II C150 conforms to ASTM C150/C150M.
The “Type II” classification refers to Portland cement with moderate sulfate resistance, ideal for applications where exposure to sulfate-bearing environments is expected, such as soils, groundwater, or sea water.
