Sulphate Resisting Cement
Blue Circle® Sulphate Resisting (SR) Cement complies with AS3972, Special Purpose Cement, type SR. It is manufactured from the ingredients of specially selected cement clinker, gypsum and ground granulated blast furnace slag, which result in significantly better sulphate resistance and lower heat liberation than that of a comparable Portland cement.
Application / Use
- Blue Circle® Sulphate Resisting Cement is recommended for use in aggressive sulphate-rich environments where increased resistance to salt attack is required. Where concrete is expected to be in contact with sulphates or other aggressive salts or solutions, analytical surveys must be completed and appropriate grade of concrete selected
- Blue Circle® Sulphate Resisting Cement can also be used in mass concrete where reduced heat liberation is required. As with Portland cements, the resistance to acid solutions is limited, but concrete life expectancy will be maximised by using Blue Circle® Sulphate Resisting Cement at high cement content and low water to cement ratio in fully compacted and cured concrete
Features & Benefits
- Sulphate Resisting Cement complies with AS 3972, type LH/SR
- Combines the benefits of significantly lower heat evolution, greater sulphate, chloride and salt water resistance
