Calcium Aluminate - an overview | ScienceDirect Topics

Since the 1960s, many kilometres of solid calcium aluminate sewage pipes were used in Durban, South Africa. In the 1980s concrete pipes lined with calcium aluminate mortar were laid in Cairo, Egypt. Calcium aluminate cements are used extensively for lining ductile iron pipes. 172 The process of centrifugal spinning allows very low water/cement ratios down to 0.3 to be achieved.
