Colemanite, a boron mineral, is used in cement production at a rate of 8%, reducing clinker firing temperature and improving the properties of cement. Boron cement has better features compared to portland cement in terms of parameters such as strength, water and gas permeability, hydration temperature. The low hydration temperature significantly reduces the need for cooling especially in mass concretes.
The use of colemanite in cement production also reduces the amount of carbon dioxide released into the atmosphere by 25-30%. Boron cement production has the potential to be a lifeline for the sector within the framework of the responsibilities of the Kyoto Protocol.
