After four years of physical, chemical and mechanical tests, H-UKR cement has now been given a Technical Appraisal (ATEx type A) by the CSTB.
The appraisal covers a large number of structures ranging from detached houses to high-rise buildings in terms of their structural applications (floors, diaphragm walls, beams, posts, etc.).
These technical appraisals guarantee a lifespan of over 100 years for structures built with H-UKR cement.
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.
H-UKR cement contains no clinker and has a carbon footprint 3.5 times smaller than that of traditional CEM I cement.
Its compressive strength on mortar is around 35 MPa at 48 hours and 65 MPa at 28 days. Its setting kinetics at 20°C are fully comparable to those of CEM I 52.5 N.
H-UKR cement takes the form of a powder that can be stored in silos, and is perfectly compatible with existing manufacturing processes. It is intended for the industrial, precast and ready-to-use concrete markets.
