LATTICE-SHAPED REINFORCING MATERIAL FOR HYDRAULIC SUBSTANCE

PURPOSE:To obtain a reinforcing material excellent in a high reinforcing effect, execution workability and safety by knitting and weaving a synthetic fiber filament of single fiber denier with predetermined tensile strength and predetermined Young's modulus into a knotless net which is formed into a lattice shape and impregnated with resin to serve as the reinforcing material. CONSTITUTION:A cord is constituted of an organic synthetic fiber filament of PVA system, PA system, polyester system, polyolefin system, polyamide system, alamide system, etc., consisting of 100 to 300dr single fiber denier with tensile strength 7g/denier(dr) or more and Young's modulus 150g/dr or more. A lattice-shaped reinforcing material for a hydraulicity substance, consisting of a knotless net with a diameter of the cord 3 to 10mm and a distance between points of intersection 20 to 200mm and binder resin impregnation-hardened in the cord, is formed. In this way, work can be safely performed with the lightness in weight and with carriage mounting work facilitated together with a high reinforcing effect of intersection point strength because of knotlessness in good adhesion to cement.
