Features Analysis of Artificial Sand Maker

　　According to national standards,the soil processing mechanisms sand and mixed sand are collectively referred to as artificial sand.

　　The main features of the mechanisms sand: now they are basically coarse sand and adjustable, with a certain amount of powder, in addition to the 150 micron sieve, the remaining sieve can meet the standards of natural sand,the particle shape is multi-triangular or square and rectangular body, the surface roughness, sharp edges and corners. However, due to the different production source of mechanism sand across the country, mechanism equipment and processes of artificial sand maker is different,the mechanisms sand gradation may be a big difference, but the mechanism of sand grain and graded all can be made adjustment and improvement, on this point, artificial sand is essentially different from the natural sand.

　　

It is determined by the characteristics of the artificial sand, compared with the same conditions for natural sand in the mix design and other materials, molding curing conditions are the same concrete characteristics produced by artificial sand are: reduced slump standard strength in 28 days; such as maintaining the same slump, the required amount of water will increases; but without increasing the amount of the cement after the cement ratio becomes large, under normal circumstances, the actual intensity of concrete does not reduce.

　　According to the law of natural sand, concrete mix design and artificial sand water are in great demand, the artificial sand needs more water,and it is easy to produce bleeding, particularly it shows significantly in the low-strength grade concrete cement with less performance; If you make concrete mix design based on the characteristics of artificial sand, which can be prepared through the rational use of artificial sand and stone powder, you can adjust artificial sand sand ratio.

　　 Ordinary concrete mix design method is fully applicable to the artificial sand. The proper use of artificial sand with big concrete density, impermeability, good performance of anti-pulp, and other physical and mechanical properties can meet the design requirements of long-term durability. Artificial sand is particularly suitable for the preparation of high-strength grade concrete, high performance concrete and pumping concrete.
