Experimental Study of Mix Proportion of Magnesium Oxychloride Cement

Article Preview

Abstract:

Based on the results of compression and bending tests of fifty eight magnesium oxychloride cement test cubes, the influences of two factors on compression and bending strength have been analyzed which includes the mole ratio of magnesium oxide and magnesium chloride and Baum degree of magnesium chloride solution. Softening coefficient of magnesium oxychloride cement and its influence factor have been studied by immersion test of twelve test cubes. The results show when the mole ratio of magnesium oxide and magnesium chloride is 7.0, the strength and water resistance performance of magnesium oxychloride cement is best. This work is very important to the application and dissemination of magnesium oxychloride cement bearing structural member in southern wetter areas of china.
