Granite mechanism sand can replace river sand

Mechanism sand refers to the particle size of not more than 4.75mm particles, from a variety of ores by professional mechanical crushing, sand making, screening and made of sand, has become the main raw material for all walks of life, the proportion of applications in some areas has reached 50%, granite is one of the more common rock, but also a green building materials, but granite mechanism sand can replace river sand?

The answer is yes, granite sand can replace river sand. Granite into a mechanism of sand can be applied to construction, municipal, transportation and other projects in the C60 and the following strength level of concrete, because granite belongs to the acidic (SiO266%) magmatic rocks in the intrusive rock, the formation process is usually closely related to the continental tectonic action, metamorphism and metallogenesis, structural densities, hard texture, high strength, resistance to weathering, corrosion resistance, abrasion resistance, can be used outdoors for a long time, and granite mechanism sand can replace river sand. Long-term use, and granite mechanism sand grain shape is very good, uniform particle size, cubic content of up to 98%, stone powder containing less, no cracks, fine lines, no coarse and fine particles segregation phenomenon, more popular with the public.
