Abstract
The mechanisms of sodium sulfate attack to mortar are different from that of magnesium sulfate attack. The effects of the addition of fly ash, the limestone powder, and gypsum on sulfate resistance were studied. Soaking temperature was changed from 20℃ to 60℃. The resistance in the sulfate solution is evaluated by the small sized test method using mortar pieces of 8mm cubic Evaluation test method. In sodium sulfate solution, the addition of fly ash and gypsum improved the sulfate resistance. The destruction to the particles did not occur at high temperatures. In case of magnesium sulfate solution, the addition of gypsum and fly ash, high temperature became less effective than the case of sodium sulfate solution.
