RUST-PROOF DEFORMED BAR
PROBLEM TO BE SOLVED: To provide a rust-proof deformed bar capable of increasing strength of adhesion to concrete.SOLUTION: A rust-proof deformed bar according to the present invention includes: a deformed bar; a rust-proof coating which is composed predominantly of polyvinyl butyral and which coats a surface of the deformed bar; and sandy particles which are supported on a surface of the rust-proof coating and in which the ratio of the particles with a particle diameter of less than 0.15 mm and 0.05 mm or more is 70% or more of the total. Preferably, No.8 silica sand is used as the sandy particles.SELECTED DRAWING: Figure 7
【課題】コンクリートとの付着強度を高めることができる防錆異形鉄筋を提供する。【解決手段】本発明に係る防錆異形鉄筋は、異形棒鋼と、ポリビニルブチラールを主成分とし、異形棒鋼の表面を被覆する防錆被膜と、防錆被膜の表面に保持され、粒径が０．１５ｍｍ未満であって０．０５ｍｍ以上の範囲に属する粒子の割合が全体の７０％以上である砂状粒子とを備える。この砂状粒子としては８号硅砂が好ましい。【選択図】図７
