Standard test method for determining the effects of chemical admixtures on the corrosion of embedded steel reinforcement in concrete exposed to chloride environments 混凝土暴露于氯化物環(huán)境時(shí)確定化學(xué)混合物對(duì)埋置鋼筋腐蝕作用的標(biāo)準(zhǔn)試驗(yàn)方法
Corrosion inhibitor admixtures shall be defined as materials that when added to concrete have the ability to reduce the potential of corrosion of embedded steel 《混凝土產(chǎn)品指南》中定義:鋼筋阻銹劑(混凝土防腐蝕外加劑)是加到混凝土中能夠降低鋼筋腐蝕的物質(zhì)。
Top - directly as a basis and foundation of the bearing surface as the top - embedded steel bearings or bearing surface , the supporting surface , the anchor bolt ( anchor ) position should be consistent with the allowable deviation of norms 基礎(chǔ)頂面直接作為柱的支承面和基礎(chǔ)頂面預(yù)埋鋼板或支座作為柱支承面時(shí),其支承面、地腳螺栓(錨栓)位置的允許偏差應(yīng)符合規(guī)范的規(guī)定。
Post - embedding steel technique is a new type of building reinforcing and rebuilding technique with excellent technical advantages , the research development of which has become a very active part of modern building structure reinforcing and rebuilding techniques 植筋技術(shù)是一種新型的建筑物加固改造技術(shù),由于特有的技術(shù)優(yōu)點(diǎn),其研究開(kāi)發(fā)已成為現(xiàn)代建筑結(jié)構(gòu)加固改造技術(shù)中極具活力的分支。
Durability ' s of the material such as permeability , heat - resistance , carbonation and steel bar - protection were tested . the bonding characters between anchoring material matrix and post - embedding steel bar , the matrix and the concrete structures were studied 在植筋錨固長(zhǎng)度足夠的條件下,混凝土與錨固砂漿的界面粘結(jié)強(qiáng)度大小直接決定了植筋錨固的控制荷載,粘結(jié)界面成為受力的薄弱環(huán)節(jié)。
