THE INFLUENCE OF NaNO2 ANTIFREEZING ADMIXTURE ON SULFATE RESISTANCE OF CEMENT PASTE

摘要：

This paper comprehensively evaluates the influence of NaNO2 antifreezing admixture on sulfate resistance of cement paste to sulfate attack based on the test design of element super-composition method, wet and dry cycle test, rapid boiling and gypsum mixing. Systematically analyze the influence of mixing ratio, cement variety and attack condition on sulfate resistance. By means of XRD and MIP, investigate the destructive characteristics of sulfate resistance of concrete with negative temperature antifreezing admixture.
