Title: Characteristics of alkali-silica reaction in the presence of sodium and calcium chloride
Abstract: A role of Cl− ions in the alkali-silica reaction in mortars containing sodium and calcium chloride was discussed comparing the composition of pore solutions in mortars with and without Beltane opal with expansions of the corresponding mortars. It was found that the alkali-silica reaction can progress in the early stage of the process without consuming OH− ions in mortars containing NaCl and the reactive aggregate. A rapid expansion of NaCl-bearing mortars appears to be related to an acceleration of the alkali-silica reaction in the presence of Cl− ions at the early stage within 24 hours.
