As we known, the artifical sand is made by sand making machine. During the sand making process, the stone powder cannot be avoide. But some artifical sand producing plants wash away the stone powder for the better appearance of sand by meeting the requirements of their customers. It is bad for sufficient usage of the stone powder in the artifical sand. The stone powder is cannot be avoided during producing artifical sand. The proper percentage stone powder in the artifical sand is good. The fine particles of below 0.315mm would be washed away during washing the artifical sand. The function of these fine particles influenced the mixability and workability of the artifical sand concrete.
By the exhaustion of the natural sand and the rapid development of the concrete technology, specially, the requirement to the aggregate of the high performance concrete is very strict. The concrete development trend is to improve the durability and solve the environmental issues. The make a good used of the artificial sand is oen of the best way to develop green concrete. At commodity concrete enterprises, the P.O42.5 and the higher grade coment replaced the 32.5 grade cement. For low grade concrete, it is hard to get the binding material. So it is hard to transport the low grade concrete. The working performance is influenced greatly. But the proper stone powder can make a filling function to it. It cannot only improve the strength, but also improve the working performance of the low grade concrete. So, to controlling the stone power in a proper percentage and controlling the stone powder methylene blue MB value can promote the strength and working performance of the low grade concrete.
