In terms of chemical composition, quartz sand mechanisms are more pure than sand and river sand, and the content of silicon dioxide is higher.If the purity is high, the impurities are less, and the defects caused by impurities are less, and the strength is high.

The first is that the particles of quartz sand are better in shape, and mortar is formed in the concrete mixer to wrap the coarse aggregate, so as to work well;Silicate minerals,), formed a higher intensity of concrete.The main ingredients of artificial sand are calcium carbonate, the spherical size of the particles is low, the corners are more, the concrete is not good, and the internal defects in the concrete body are more, resulting in a decrease in strength.
