Influence of sea water solution on mortar containing calcium carbonate
Abstract Normal Portland cement mortar discs containing precipitated or ground limestone at dosages of 0, 2.5, 5 and 15% were made at water/cement ratios of 0.42 or 0.60. They were hydrated in lime water or sea water solution for periods up to 1 year. The length and modulus of elasticity changes were monitored periodically. Some mortars containing $ CaCO_{3} $ exhibited more than three times the expansion of the reference in sea water. The expansions were greater in samples containing fine $ CaCO_{3} $. The modulus of elasticity was especially low for samples containing precipitated $ CaCO_{3} $ and exposed to sea water.
