Various types of cement products are mainly made from the river sand(2.0-0.2mm), but its supply-and-demand problem as a building material recently facilitated a growing interest in using sea sand.

However, the salinity within sea sand make concrete strength worse and reinforce decay, and it is possible to cause the shoddy construction. Sea sand is therefore always required to go through a washing (desalting) progress.

On the other hand, desert sand(0.2-0.02mm) has not been used as a building material due to its physical property’s difficulty in mixing with cement
 

With the GME’s advanced chemical technology and ceramic technology, GME has developed an artificial sand stone using both river and sea sand, as well as desert sand, which has not been utilized at all before. GME has been able to find a crucial solution to the supply-and-demand problem of sand.

GME Sand stone has excellent surface in appearance and is stronger compared to natural sand stone.
In particular, it is an environmental-friendly product that uses 100% natural minerals (No Cement)
In the case of making use of the GME New Technology in the Middle East or recently, in China where desertification is rapidly progressing, adding economic value to the improvement of resource utilization will be very large in future.
