Cement & Binders
High-purity calcium aluminate cements contain a minimum of 70% Al2O3 and are used as binders in monolithic refractories. Depending on the type of cement, the curing and setting behavior varies significantly, impacting hardening and strength development. This allows the developer to choose from a wide range of calcium aluminate cements to find the right one to meet the desired properties.
Almatis calcium aluminate cements are tested to reflect customers’ needs. Consistency in chemical and mineralogical composition, particle size distribution, and in flow, setting, and strength are all essential for good and reliable cement performance.
All Almatis cements are packed in sealed plastic bags that prevent reaction with humidity in the environment. Therefore Almatis cements have a long shelf life, with 24 months guaranteed when stored under adequate conditions, even when climatic conditions are challenging.
