H-UKR cement replaces Portland cement and is well-positioned to meet the challenges of sustainable development. H-UKR cement contains 0% clinker and is made from industrial by-products and activators from the chemicals industry, using a cold process which produces low-carbon concretes. It is a technology based on alkali-activated blast furnace slag and activators and super-activators specifically formulated by the Company are added to the ground blast furnace slag. Cement using H-UKR technology is intended in particular for the precast concrete, ready-mix concrete and cement bag markets.
