Product Description
Refractory Cement CA50-A600 A700 A900 CA80 Calcium Aluminate Cement 25kg/bag
Calcium Aluminate Cement (CA-50 to CA-80) is a high-purity refractory binder used for low cement castables and unshaped refractories. It offers high refractoriness, low impurity content and service temperature up to 1800°C, and is widely used in furnace and kiln construction and repair.
