Abstract
305,170. Soc. pour l'Exploitation des ProcÚdÚs Petrus, (Assignees of Perrin, L., and Tuscher,B.). Jan. 28, 1929. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 2, 1929]. Cements, Portland and Roman. - Cement is made by intimately mixing finely ground Pozzolana, for instance blast furnace slag (60 to 80 per cent), Portland cement (5 to 27 per cent), and lime (2 to 22 per cent). The composition of the Pozzolana may be corrected by addition e.g. of sodium carbonate, potassium sulphate, or barium chloride, and the setting of the cement may be adjusted by addition of plaster (1 to 10 per cent). The lime may be obtained in the necessary fineness by slaking and drying. Reference has been directed by the Comptroller to Specifications 8153/85, 9210/95, 21141/97, 212,419, 235,006, and 258,073.
