1.High tensile strength , the tensile strength is 2 times better than thesteel rebar of common specifications. 2.Excellent corrosion resistance,adiabatic, insulative 3.low density 4.the thermal expansion coefficient ofcomposite rebaris similar to concrete Continuous Basalt Fibre reinforced plastics (CBFP) is a new kind of composite which takes the basalt fiber as the reinforce material, combines the ethylene resin and filler curing agent and then be made by pultrusion. Its difference with the steel is that its density is only 1.9-2.1g/cm3. BFRP is a sort of rustless electrical insulator, which has the nonmagnetic, high acid-resistance, alkali-resistance. BFRP has the high permissibility for the moisture concentration of the cement mortar & the permeability, diffusion of the carbon dioxide. Theses can prevent the concrete construction from eroding to enhance its endurance.
