Because of their relatively high cost, calcium aluminate cements are used in a number of restricted applications where performance achieved justifies costs: in construction concretes, where rapid strength development is required, even at low temperatures. as a protective liner against microbial corrosion such as in sewer infrastructure. in refractory concretes, where strength is required at high temperatures. as a component in blended cement formulations, for various properties such as ultra-rapid strength development and controlled expansion are required. in sewer networks for their high resistance to biogenic sulfide corrosion.
