ABSTRACT:
A structural element of concrete is selectively reinforced over that part of the surface where, when the element is loaded, tensile stresses can occur which might exceed the tensile strength of the concrete. The reinforcement comprises a relatively thin, integral external layer preformed from a cement composition reinforced with fibres disposed in a random two-dimensional distribution essentially parallel to the surface of the layer, the latter extending over the whole area of said part of the surface liable to tensile stress.
