The objective of the project is to develop technologies and equipment for converting desert sand into high quality construction sand. An important goal of the project is to maintain direct compatibility, that is, the ability to use the produced sand instead of the traditional construction sand without the need to make changes in the concrete production technology. In addition, the task is to endow the produced sand with additional useful properties, such as weight reduction - 2 or more times, improvement of heat insulation and sound insulation properties.
