Sand for Mortar:
With the clean deep underground water as the water source, sand for mortar is processed by 6 times washing and rubbing the natural sand, 3 times removing clay, screening by grade, surface finishing and drying. Characterized by high silica content, clean surface, circular and homogenous grain, low clay content and fluidity, it is the best material of the engineering, building, cement and mortar, dried powder, paint, coating, self-leveling industry.
