About Calcium Sulfoaluminate Cements: C02
Product Description Manufacture of calcium sulfoaluminate (CSA) cements requires less energy than conventional Portland cements and produces lower carbon dioxide emissions. This report presents background information on these cements, and reports on practical work to assess their performance in concrete. It demonstrates that CSA cements can be used to produce durable concrete with physical properties comparable to equivalent Portland cement concrete. The research has aimed to balance environmental impact, cost and physical properties and has investigated two main aspects: blends of CSA cement with materials such as ground granulated blastfurnace slag and calcium sulfate, which have been found to have good physical properties and to be suitable for use in precast concrete manufacture; and CSA cement with a high iron content allowing a wider range of raw materials to be used in manufacture.
