Sulphate Resistant Cement (SR / Type V)
Sulphate-resisting cement is more resistant than ordinary portland cement to the action of mineralized water containing sulphates; it also has lower heat of hydration and slower hardening. Moderate and High-Sulphate-Resistant Cements are used in situations where concrete is exposed to soils high in sulphate content, for example slabs on the ground, pipe and concrete posts.
High Sulphate Resistant Hydraulic Cement is used in concrete exposed to severe sulphate action, principally where soils or ground waters have high sulphate content. It gains strength more slowly than General Use hydraulic cement. Use of a low water-to-cementing-materials ratio and low permeability are critical to the performance of any concrete exposed to severe sulphate attacks. Like other portland cements, it is not resistant to acids and other highly corrosive substances.
Sulphate Resistant Cement is manufactured to the following Standard:
- ASTM C 150 TYPE V
- BS 4027
Some of the benefits of Sulphate Resistant cement include:
- High Sulphate Resistance
- Moderately lower heat of hydration
- Where groundwater and soils have a high sulphate content
- When moderately low heat of hydration is needed
