Infrastructure and the development of river sand dwindling resources, construction of artificial sand from the start to find a new direction for the sand source.

River sand in the building has a lot of advantages, but with the building requirements of the indicators improved, due to geographical distribution of natural sand and natural weathering conditions generated the differences, and showing a physical and chemical indicators of volatility, which is concrete, in particular HPC is certainly not conducive to the stability of quality. In fact, through artificial sand will be solved by the existence of natural sand these shortcomings. And because of the reduced river sand, artificial sand fact, in addition to solving the problem of the shortage of natural sand, but also high-quality concrete important raw materials.

At present, China has hundreds of artificial sand production enterprises, as in other industries, there are also artificial sand mixed level of quality. First, we must know, artificial sand production cost is high, and if that simple stones will be broken up is artificial sand, and in the kinds of products for its technical indicators clearly not easy to access, investors may have to be a heavy price.

Gravel, vice president of China Association Leihongbei clear that the quality of artificial sand - should be reconciled sand / artificial sand / powder / mud / natural sand / weathered sand / sand tailings. Reconcile. At present, due to the demand for artificial sand, some of the conditions of the enterprises do not have a simple mechanical production of inferior artificial sand, not only to the users have to pay a much greater cost than normal, and what's worse is the production of concrete quality not request a direct impact on the quality of construction works. Judging from the current situation, production of artificial sand inferior or inadequate management of the enterprises in addition to the conditions, the outstanding issues should be production machinery is not standard.

Buildings need for the construction of a large number of sand, but the sand quality requirements also vary, artificial sand compared with the natural sand, rough appearance and shape of the negative is the most important difference. Rough shape and appearance of a less circular, concrete pouring, the mobility of an undesirable impact on the mobility of this bad would create a gap in concrete, which directly affect the quality of the works. Therefore, the quality of artificial sand merits of the points should be mainly in the appearance of a circular shape and rough, the other, artificial sand production of raw materials, there are other limitations of the synthetic material is necessary to arouse the manufacturing industry and construction enterprises face serious on the issue.

Artificial sand and the rough round appearance of poor, mainly due to the decision by the production equipment. From the point of view of trade associations, artificial sand like mushroom production, the phenomenon of the herd instinct, practitioners more than the lack of professional knowledge, coupled with some low-quality equipment manufacturers only interest on the market in a lot of poor-quality equipment and immature to Artificial sand brought to the healthy development of the cause of the serious consequences. LU president to those people who call dominate the world, regardless of what is used to a class of enterprises that the accused, he said, those production equipment production inefficiencies, and costs and the very alarming, is not mature production facilities. Therefore, any investment there are risks, artificial sand investment is no exception, investors need to pay attention to, in addition to market demand and prospects, but also need to seriously enough in there for expert advice. At present, China has some of the artificial sand equipment manufacturing enterprise technology and quality to be quite good, but also to invest in enterprises prenatal training and after-sales service, the representative of China's enterprises artificial sand production enterprise technical equipment level.

In general, there are artificial sand gravel simple screening process, service level adjustment process, the fineness of the sand adjustment process, such as modulus.

Lu, president of the Guangdong Province, there are a large number of cement kilns may lag behind production process of natural selection by the market compared to the situation to understand, in his view, if the use of cement kilns broken equipment, accepting artificial sand is easy to start, but also cement kilns one way out. President Lu said that if the shaft kiln cement production is not, by accepting artificial sand, then they are willing to give technical guidance and support.
