pdf sulphate attack on self compacting concrete

Persson (2003) studied the sulphate resistance of self-compacting concrete at ages of 28 and 90 days The investigation shows that the concrete cured in a solution with sodium sulphate suļ¬€ered from a larger sulphate attack on concrete and the composition of Portland cement is less important as it relates to performance in sulphate
