Abstract
Reinforcing members for the reinforcement of hardenable or settable material such as concrete or mortar are disclosed. The reinforcing members comprise a plurality of wire elements such as fibers united by a binder which loses its binding ability when mixed with the settable material, thereby releasing the elements in a random manner in the matrix. Methods are also disclosed for mixing the reinforcing members in the matrix and for making the reinforcing members.
Claims35
A reinforcing member for a castable cementitious matrix material such as mortar and concrete, said reinforcing member comprising a plurality of small elongate metallic fiber reinforcing elements bound together in a group by a binder affectable by a disintegration ingredient suitable to be included in the castable cementitious matrix material for dissociating said elements and wherein each reinforcing element has a thickness between about 0.1 and 1 mm, a length-to-thickness ratio between about 50 and 200 and is constructed of steel, iron or an iron alloy.
A reinforcing member for mixing with a castable cementitious matrix material for reinforcing the material when hardened, said member comprising:
- (a) a plurality of elongate metal fiber or wire reinforcing elements constructed of steel, iron or iron alloy,
- (b) a binder for binding said elements together,
- (c) said binder being capable of releasing said elements when said member is mixed with the castable cementitious material due to the affectability of one or more of the ingredients of the matrix material on said binder, each of said reinforcing elements having a thickness between about 0.1 and 1 mm. and a length-to-thickness ratio between about 50 and 200.
A reinforcing member for mixing with a castable water activated cementitious matrix material for reinforcing the cementitious matrix material when hardened, said member comrpising:
- (a) a plurality of elongate metal fiber reinforcing elements constructed of steel, iron or iron alloy and having a length-to-thickness ratio of between about 50 and 200 and a thickness of between about 0.1 and 1 mm.,
- (b) a binder for binding said elements together,
- (c) said binder being capable of losing its binding properties and thereby releasing said elements when said member is mixed with the castable cementitious matrix material due to the action of the activation water for the cementitious matrix material on said binder.
A reinforcing member for a castable cementitious matrix material such as mortar or concrete, said reinforcing member comprising a plurality of small elongate metal fiber reinforcing elements constructed of steel, iron or an iron alloy, a binder uniting said elements together, said member having an effective aspect ratio of less than about 50 so as to be readily mixable with said castable cementitious matrix material without substantial clumping, said elements each having a thickness between about 0.1 and 1 mm. and an aspect ratio of about 50 to about 200 so as to provide maximum reinforcement of the matrix material, said binder being capable of losing its binding ability during the mixing of said reinforcing member with said castable cementitious matrix material so that said elements dissociate during mixing.
