The exqansion of concrete with calciumsulphoaluminate-type expansive additive containing excess free-lime was larger than that with the conventional calciumsulphoaluminate-type expansive additive or with the free-lime type expansive additive. When the conventional expansive additives were used in the blast furnace slag cement mortar, the effect is smaller than in portland cement, however, the effect of calciumsulphoaluminate-type expansive additive containing excess free-lime was same as that of ordinary portland cement. By controlling the particle size, calciumsulphoaluminate-type expansive additive containing excess free-lime resulted in considerably large strength development even under the same expansion level.
