Analysis and Forecast of the Mechanism Sand Market Prospect

In 2002, the original National Building Materials Department proposed and implemented the national standard GB/T14684-2001 'building sand” which determines the definition, technical requirements and testing methods, etc. of artificial sand. This means mechanism sand has become the mainstream building sand.

1. Natural sand exhausted results in building sand in short supply.

The awareness of ecology, environmental protection and resource has been gradually accepted by people and taken seriously. With the further development of reform and opening up, sandstone industry has been developing rapidly, as well as other building material industries. The annual output of sandstone in China has increased to 5 billion tons from 600 million tons before reform and opening up, among which sand accounts for about 2 billion tons.

With the increasing development of infrastructure, natural sand resources gradually reduce, even run out in some places. The contradiction between supply and demand of concrete sand becomes extremely prominent and the sand price gets higher and higher. In the peak period of sand consuming, there even no sand available, which seriously affects the progress of engineering construction. Impelled by economic interests, the natural sand has been disordered mined in many areas. Especially in previous years, destroying farmland and riverway to mine sand can be found everywhere, which not only destroys the limited arable lands and flood control dams, but also incurs a series of engineering accidents. So it is urgent to find out alternative products.

2. The requirements on building sand quality have been increasing day by day.

The requirements on the quality of construction have been increasing day by day, so have the requirement on concrete aggregates. Especially the concrete of a magnitude higher than C60 badly needs qualified aggregates. Therefore, the building sand must be processed in order to achieve required standards.
