According to national standards, machine-made sand is the rock particle selected for some projects after crushing, sand making, screening, dust cleaning, washing, etc. modern production processes.
Because there are many edges on the machine-made sand and the surface is rough, it is easy for artificial sand to stick cement together in order to improve the strength of concrete. Although there is a disadvantage of weak peaceability, the stone powder can make up for shortcoming. As inert admixture, stone powder with small size can increase fine particles lacked by concrete and improve the proportion of the solid surface area to the volume of water thus reducing the segregation. Besides, stone powder and cement and water can become soft slurry which can increase slurry quantity of concrete and reduce friction between stones. And the peaceability is improved in this way.
Using machine-made sand in the concrete can solve environmental protection problems because the phenomenon about illegal sand mining will be reduced. Besides, machine-made sand makes production cost and product price reduced, and the quality of construction project is improved. In addition, because machine-made sand is produced in the vicinity, the transportation cost is decreased and the resource is saved. On balance, it is very important to use machine-made sand.
Sand making machine made in Liming Heavy Industry takes advantages of small covered area, economic investment, quality finished product and low production rate of stone powder. Faced with large requirements of aggregate, the machine-made sand will help your project efficient.
