SPECIAL PURPOSE CEMENT™
Australian Builders (AB) Special Purpose Cement is produced by blending General Purpose (GP) Cement, Fly-ash and Ground Granulated Blast Furnace Slag. Blend formulation is selected to achieve lower heat generation and higher resistance to sulphate attack compared to GP Cement. The product complies with Australian Standard AS3972 as a type General Blended (GB) Cement, Low Heat (LH) Cement and Sulphate Resistance (SR) Cement.
AB Special Purpose Cement complies with the performance requirements of AS 3972 for Type SR cement. Additional guidance to ensure the resistance of concrete to sulphate attack can be found in CCAA’s Technical Note 68 “Sulphate resisting concrete”.
AB Special Purpose Cement complies with the performance requirements of AS 3972 for Type LH cement. The following graph demonstrates the heat evolution of AB Special Purpose Cement and GP cement.
AB Special Purpose Cement can be used in several structural and non-structural concrete and mortar jobs where high early age strength is not critical.
- AB Special Purpose Cement can be used where lower heat in concrete is required.
- AB Special Purpose Cement can also be used in concrete where the concrete is susceptible to sulphate attack.
CCAA Technical Note 68 “Sulphate Resisting Concrete” and AS 3600 should be referred to when using concrete in a project where sulphate resistance is required.
