Abstract
A study has been made of the strength of 3CaO.Aℓ 2O 3 and 3CaO.Aℓ 2O 3 + gypsum pastes as well as of the influence of the admixture CaCℓ 2 on these pastes. The methods employed were microhardness indentation and cone penetration. With 16 per cent CaCℓ 2 added to the 3CaO.Aℓ 2O 3 paste a significant gain in strength was obtained after 3 months, while an 8 per cent CaCℓ 2 addition to the 3CaO.Aℓ 2O 3 + gypsum system gave the highest strength at the same age. Morphological changes in the pastes were found to be related to changes in hardness. From a comparison of the two methods it was concluded that cone penetration measurements are useful up to a certain hardness level.
