CORROSION RESISTANCE OF SLAG CONCRETE IN SEA WATER

The water/cement ratio and cement content are two main factors which reflect the impermeability of concrete.Two types of slag concrete specimens,one of which had the same concrete content and different water/cement ratios,while the other had the same water/cement ratio and different concrete contents,were prepared.Then the specimens were evaluated by measurements of compressive strength,folding strength,weight changing and ultrasonic test.The durability of slag concrete was improved with the decrease of water/cement ratio.In concrete design,there was an optimum cement content,in which the slag concrete had the best corrosion resistance.
