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 0.6. 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. Mortars containing CaC03 (both coarse and fine) exhibited more than 3 times the expansion of the reference in sea water. The expansions were greater in samples containing fine CaC03. The modulus of elasticity was low especially in samples containing precipitated CaC03 and exposed to sea water.
