Experimental Investigation Properties on Resistance of Slag Cement Concrete to Sulfate Attack

Abstract:

The water-cement ratio and cement content are key factors which reflect the anti-penetration of the concrete. To study the slag cement concrete against sulfate attack, make two types of the slag cement concrete test blocks of which one type has the same concrete content and different water-cement ratio, while the other type has the same water-cement ratio and different concrete contents; then test the concrete test blocks on compressive strength, folding strength and weight changing after dipping them into sulfate solution and drying them for thirty and sixty times .At the same time non-damage ultrasonic test was carried out. The results show the durability of the slag cement concrete is improved with the decrease of water-cement ratio; in concrete design, there is optimum cement content which theslagcement concrete has the best resistance sulfate erosion.
