Abstract

225,912. Garrow, J. R., Case, G. O., and Novocretes, Ltd. Aug. 30, 1923. Reinforced concrete. - Fibres, such as saw dust, wood pulp, coir and cork, or wooden laths &c., are impregnated with a basic solution of a metallic salt, and a mineral compound is precipitated from the solution in and on the fibres. An example is an iron salt, such as ferric chloride rendered basic by the addition of an alkali or alkaline earth hydrate or salt, the amount addded being such that a slight excess would produce a permanent precipitate. Suitable proportions are one pound of iron perchloride in 10 lbs. of water, and about 2 oz. of caustic soda. The fibres are impregnated with the solution and a precipitate is formed by the addition of an alkali, or by heat, or merely by keeping the fibre in the atmosphere. The mineralized fibre is employed as a filler for cements, particularly those containing alkalies or lime, in which case further reaction takes nlace. With aluminous cements, as ciment fondu, it is preferable to add lime &c. to obtain reaction after the concrete has been mixed. Reference has been directed by the Comptroller to Specification 220,677.
