by Hoffmann Green has recently achieved a milestone: this low-carbon cementitious material, which contains no clinker and is made only by cold mixing of chemical by-products and activators. It has officially passed the GU (general) grade certification of ASTM C1157 Hydraulic Cement Performance Specification. Because the standard only looks at strength, durability, setting and other performance indicators, but does not limit the formula, H-UKR can enter the same application sequence as traditional Portland cement by means of measured data, and the certificate is approved by Saudi Arabia's regulatory authority at the same time, opening the door for products to enter the Middle East market. The core value of
ASTM C1157 is "performance only". In the past, cement standards often set the threshold around the proportion of clinker minerals, which made it difficult for low-clinker or even zero-clinker systems to comply with the regulations. During months of systematic testing at the University of Miami, H-UKR demonstrated excellent early strength, low shrinkage and sulfate resistance, fully meeting all thresholds of the GU grade, making it one of the first zero-clinker cements in the world to pass this path certification.
With this "pass", H-UKR can be legally used throughout North America and Saudi Arabia for all common scenarios such as roads, bridges, tunnel linings, prefabricated components, shotcrete, commercial mixing stations and soil solidification. Its outstanding advantages of chemical erosion resistance and durability make coastal, saline-alkali land and sewage environmental engineering the most attractive market segments.
Hoffmann Green said that the next step would be to speed up the construction of local grinding stations on the east coast of the United States and Saudi Arabia, and to establish demonstration projects through cooperation with local ready-mix plants and prefabrication plants to further verify the long-a ge performance of H-UKR under actual climatic conditions. Clear the last kilometer barrier for the large-scale substitution of zero clinker cement.
