Blue Circle Special Purpose Cement complies with AS 3972-1997, Type LH/SR. It is manufactured from the ingredients of specially selected cement clinker and ground granulated blast furnace slag, combining the benefits of significantly lower heat evolution, greater sulphate, chloride and salt water resistance.
Application / Use
- Blue Circle® Special Purpose Cement may be used in marine applications, in mass concrete where reduced heat liberation is important or 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. As with Portland cements, the resistance to acid solutions is limited, but concrete life expectancy will be maximised by using Blue Circle® Special Purpose Cement at high cement content and low water to cement ratio in fully compacted and cured concrete.
