Abstract
An improved reinforcing material for concrete and comprising a multitude of relatively short and substantially straight steel flakes. The steel flakes are of a shape tapering towards the ends of the flakes, and they have a thickness of about 0.1 mm to about 0.5 mm, a maximum width of at least about ten times the thickness, but at least about 2 mm, and a length of at least about 100 times the thickness. They are intended to be uniformly distributed and in principle randomly orientated in the concrete. The most preferred dimensions are: thickness 0.1 to 0.2 mm, maximum width 4 to 6 mm, and length 20 to 80 mm.
Claims12
A reinforcing material for concrete said material being a multitude of short and substantially straight steel reinforcing elements of substantially rectangular cross section and small thickness in relation to their length and width, intended to be uniformly distributed and randomly orientated in the concrete, characterized in that the elements are relatively difficult to crush steel flakes with a shape tapering towards the ends of the flakes, said flakes having a thickness of from about 0.1 mm to about 0.5 mm and a length of at least about 100 times the thickness.
