Experimental Analysis on the Erosion Performance of Steel Slag Concrete to Sulfate and Magnesium Salt

FENG Yong;HAN Yan-li;College of Water Conservancy and Civil Engineering,Xinjiang Agricultural University;School of Water Conservancy and Hydropower in Xinjiang;  
On the basis of previous studies of slag optimal replacement ratio,useing the different sizes of steel slag to made of ordinary portland steel slag concrete block,were soaked in sulfuric acid ion concentration of 8000 mg/L and magnesium ions erosion solution concentration 3000 mg/L,to analysis that ordinary portland steel slag concrete in six-month period,respectively,in sulfate erosion and magnesium erosion corrosion properties. The results showed that the size of the steel slag is influent concrete anti-corrosion performance,the steel slag smaller the particle size,the less free which contains the active ingredient,in the preparation of its strength is not reduced but increased,and it is help to anticorrosion properties.
