Effect Of Sulphate Attack On Self Compacting Concrete

Effect of Sulphate Attack on Self compacting Concrete

The loss in mass, compressive strength and sorptivity of cubes were found to be negligible under Sulphate attack. It was observed that limestone and quarry dust powder resists Sulphate attack within tolerable limits. References.

Effect of External Sulfate Attack on Self Compacted Concrete

Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The effect of external sulfate attack
