Experimental Study on Long-Term Exposure of Concrete in Magnesium Sulfate Solution

Abstract:

Tests were carried out to study the concrete attacked by magnesium sulfate solution. The concrete specimens were exposed in the magnesium sulfate solution with three different concentrations for 360 days. At the exposure times of 90 days, 180 days, 270 days and 360 days, the properties of concrete such as the mass change, the compressive strength and the tensile strength were measured, and the contents of sulfate-ion diffusing into different depths of concrete were determined. Their changes with the solution concentration and the exposure time are analyzed in this paper, which could be used as reference for the protecting of concrete against the attack of magnesium sulfate.
