Strength and whiteness are important indicators of the quality of produced white cement. The high whiteness index allows coloring the cement in any color using various pigments, which allows you to use the product for the construction of truly impressive buildings and structures. In 2021, the company received a certificate of conformity for white Portland cement PCB 1-500-D0 (certified in accordance with GOST 965-89), and also passed the ISO 9001:2015 quality management certification.
Cemix packs white cement in strong polyethylene bags. This allows maintaining the quality of the finished product for a longer period, in comparison with paper bags, protecting the product from damage and getting wet. We guarantee the purity and high quality of white cement. For delivery to our terminals we use cement trucks and our own hopper cement wagons designed exclusively for transportation of white cement.
