Use : In self-leveling mortars, it significantly accelerates cement hydration and improves early concrete strength. In sulphoaluminate cement and high-alumina cement systems, it has minimal impact on the final strength of the finished product, making it ideal for applications requiring rapid achievement of certain strength requirements. In the glass industry, it is primarily used as a colorant and to enhance the strength and heat resistance of glass.

Packing : Plastic inner and woven outer, 25kg/bag or cardboard drum, or packaged as required.
