The Study of Mortar Specimens Containing Waste Glass Powder on the Resistance to Sulfate Erosion

Abstract:

Different particle size range of waste glass powder amount to replace part of the cement made to mortar specimens, which were soaked in 5% sodium sulfate solution and water after standard curing .Then determining its mechanics properties in various ages, observing and analysis of the micro structure of the section of the specimens by SEM, exploring the ability of mortar specimens made in different size and dosage of waste glass resist to sulfate. The results indicate: Along with the rising of the size and content of glass powder. The performance of mortar specimens resisting to sulfate were on the decline. When replacement amount was 10%, all kinds of particle size of waste glass mortar specimens are better than that of ordinary Portland cement on mechanical properties, When the glass powder size is less than 53μm, all kinds of mortar specimens with high content of waste glass are better than that of ordinary Portland cement on mechanical properties.
