Formation of Calcium Chloraluminate by Interaction of Portland Cement with Sea-water and Chloride Solutions

Naturevolume 191pages488489 (1961) | Download Citation



THE effect of chloride-containing solutions on Portland cement has received relatively little attention. Batta1 and Thorvaldson2 noted that addition of chloride ions to solutions containing sulphate reduced or inhibited the expansion of concrete and mortar bars. Batta attributed this effect to the increased solubility of gypsum and calcium sulphoaluminate in chloride solutions.
