Patent No. EP3967671 (titled "Calcium Aluminate Cement (Cac), Its Use And Preparation") was filed by Almatis on Sep 14, 2020. The application was issued on Jul 12, 2023.
A calcium aluminate cement (CAC) with improved properties for precast applications, ceramic filters, additive manufacturing, and building chemistry. The CAC contains 72-78 wt% Al2O3, 3-25 wt% CA, and less than 1 wt% impurities, enabling controlled shrinkage and strength development. The cement's unique composition allows for longer demolding times, reduced cracking, and improved handling properties in precast applications.
