ABSTRACT:
Method for accelerating the hardening and increasing the strength of Portd cement by mixing Portland cement with water and with a mixture containing dialuminum pentahydroxychloride, calcium sulfate and calcium oxide in weight ratios of 1:3.5 to 4.3:1.3 to 1.8, respectively, and up to 2 parts by weight of an alkali metal nitrite at temperatures up to 90.degree. C. and thereafter hardening the mixture at temperatures up to 100.degree. C. The mixing can be carried out either by wet mixing or dry grinding the ingredients.
