ABSTRACT. The influence of citric acid on the hydration and strength development of a calcium sulphoaluminate cement was investigated. Cement pastes were prepared by mixing calcium sulphoaluminate (C 4 A 3 Ŝ) with 15, 20 and 25wt% of hemihydrate (CŜH 0.5).Citric acid was added as a retarder at 0 and 0.5wt%.
