The saying the 'Wanna be rich? Build roads first!' has been deeply cognized by common people, yes, highway is the lifeblood to promote the economic development of China. The availability of highway means the unobstructed road of the development of market economy. In the twelfth five years plan period, China will continue to make strengthening economic construction as the key point and highway and railway construction is also expanding the scale constantly. Especially the policy support west development, many engineering construction projects are developed which direct drive the demand for mechanical equipment, especially the demand for mining machinery and equipment.
There are two types of construction: 1.Building construction 2.Industrial construction. Be it building construction or industrial construction, sand as the raw material is of large demand. However, natural sand can't satisfy this huge demand because of source exhaustion or transportation difficulty. Therefore, we need artificial sand which is inexhaustible for it can be made by machines such as jaw crusher, sand maker,sand washer, etc.
In the construction highway and railway, the demand for the amount of sand is very large, nowadays, only relying on the supply of natural sand material is far from enough, artificial sand was born at the right time. However, the performance characteristics of artificial sand are also questioned: can it take the place of the performance of natural sand? With these questions, we consult a professional manufacturer of sand making equipment-Hongxing Machinery.
Experts analyze that, from the general sense, artificial sand refers to all of manufactured sand and mixed sand that have been treated by the soil. Artificial sand refers to the sand that has been broken by the crusher and screened that gives conform to the materials specifications. In the project construction, it often mixed together with natural sand and its proportion is configured according to the various properties of concrete that engineering project requires. Before use, it also needs strict technical requirements and inspection. According to the difference of production mineral sources and processing technology, it will be different in the shape and the gradation. Compared with natural sand; if the proportion design and other material molding maintenance condition are the same, concrete that using artificial sand configured out has the following characteristics.
