Popis:	Variation of tensile strength of sanded gypsum plasters with composition and consistency before setting.—To each of a series of 12 plasters, containing various proportions of sand, 5 different amounts of water were added. The consistencies, determined by means of a Southard viscosimeter, and the tensile strengths of the set plasters are tabulated. The results vary both with the kind of gypsum and with the fineness of the sand. Suggested method of determining normal consistency of sanded gypsum plasters.—As a result of considerable experience the authors have reached the conclusion that material of the proper consistency to be used for plastering will show a slump of 1/2 inch when tested in the Southard viscosimeter.
