    Cement

    When used at a ratio of c.a. 8% in cement production, colemanite, a boron mineral, reduces clinker production temperature and enhances cement properties.  Boron-cement performs better compared to portland cement in terms of strength, water and gas permeability and hydration heat. Low heat of hydration, particularly in mass concrete, significantly reduces cooling requirements.

    Colemanite used in cement production also reduces the amount of carbondioxide released into the atmosphere by 25-30%. Given the liabilities introduced by the Kyoto protocol, boron-cement production promises to be a lifesaver for the industry.
