摘要：
The influence of barium and strontium chlorides on the strength of hardened gypsum paste was examined. The moistening of gypsum bars with barium and strontium water solution, and particularly in the case of earlier moistening them with potassium sulphate solution, the strength of gypsum elements and softening factor are increased. However, barium chloride has no influence on gypsum samples properties. Both ions form sulphates in gypsum samples; barite and celestine. Moistening of gypsum bars with water solution of K(2)SO(4) causes the formation of syngenite, which is located principally in the surface layer of the samples.
