AbstractNormal 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 CaCO3 exhibited more than three times the expansion of the reference in sea water. The expansions were greater in samples containing fine CaCO3. The modulus of elasticity was especially low for samples containing precipitated CaCO3 and exposed to sea water.
