Hoffmann Green Cement Technologies has obtained a key certification for its H-UKR 0% clinker cement in the US. After positive test results at the University of Miami, the clinker-free cement has been certified as compliant with ASTM C1157. This benchmark standard in the United States evaluates cements solely based on their performance (strength, durability, setting time, expansion) regardless of their composition. H-UKR cement is now officially recognized as a hydraulic cement that complies with the GU (General Use) category of ASTM C1157. It can therefore be used in all general construction applications, whether structural or non-structural: roads, bridges, road structures, precast elements, shot-crete, ready-mixed concrete, architectural prefabrication and soil stabilization.
