Реферат: Abstract of the Disclosure A method for reinforcing concrete comprises short and substantially straight steel flakes of rectangular cross section and small thickness in relation to their length and width. In use the flakes are uniformly distributed and randomly orientated in the concrete. The flakes are relatively difficult to crush and are tapered at each end. They have a thickness of 1 to 5 mm and a length of at least 100 times the thickness. The flakes are made from molten steel of such a composition that rapid cooling of thin layers of the melt produces relatively flexible, difficult-to-crush films. Thus molten steel is impinged upon a relatively cold metal surface of great cooling capacity which is moved rapidly across the direction of delivery of the molten steel. This creates at least one discrete, relatively thin, flake-shaped layer of molten steel on the metal surface. This thin layer is allowed to solidify on the surface to form the desired steel flakes. The flakes can be twisted into slight propeller shapes and have direction-independent strength properties.
