Sulphate resistant cement of low hydration heat

CEM III/B 32.5 N-LH/SR is produced by grinding of portland cement clinker and ground granulated blast furnace slag, with addition of optimal quantity of gypsum as a setting time regulator.

Moravacem recommends this type of cement for construction of objects where sulphate resistance and/or low hydration heat is required, and for producers of ready mixed ordinary concrete in summer conditions.

Designation

• M 20K 32,5 N – LH/SR
• CEM III/B 32,5 N – LH/SR.

Designation, composition and cement quality are in accordance with Rulebook on cement quality

Properties of cement CEM III/B 32.5 N-LH/SR

• Sulphate resistance
• Low heat of hydration
• Low strength gain in early period
• Significant strength gain even after 28 days
• Very low content of Tricalcium Aluminate C₃A
• Low alkali content
• Very light color
• Optimal initial and final setting time
• Compatible with chemical admixtures – provides efficient utilization of chemical admixtures which results in enhanced properties of fresh and hardened concrete (lower Wc ratio, improved consistency, resistance to frost and salts…)

Application of CEM III/B 32.5 N-LH/SR

• Production of sulphate resistant concrete, and concrete for structures placed in other aggressive environments (urea, ammonia, lactic acid, acetic acid);
• Building of wastewater treatment systems, sewage and drainage systems, irrigation systems, subsurface works, stabilization and soil injection, road works;
• Production of concrete of prolonged durability;
• Production of mass concrete and construction of massive construction projects (dams, tunnels, foundations, bridges…);
• Application of this type of cement with good quality aggregates and concrete chemical admixtures, wide range of concrete classes can be achieved, up to C40/50;
• Production of concrete with low strength gain at early age, and high final strength gain (piles);
• Production of RMC (ordinary concrete, pumped, self-compacting) in summer conditions;
• Production of concrete for construction of livestock and poultry farms;
• Light-color of the cement makes it ideal for application in architecture;
