Square wire mesh is made of selected low carbon iron wire precision construction , uniform mesh , fine rust - resisting and durable function 方眼網(wǎng)是由精選低碳鐵絲制成,結(jié)構(gòu)精密,網(wǎng)眼均勻,具有抗腐蝕性好,結(jié)實(shí)耐用等特點(diǎn)。
Property : square wire mesh is made of selected low carbon iron wire with precision construction , uniform mesh , fine rust - resisting and durable function 材質(zhì):鍍鋅鐵絲編織:平紋編織特點(diǎn):結(jié)構(gòu)精密,網(wǎng)眼均勻,具有抗腐蝕性好和結(jié)實(shí)耐用等特點(diǎn)
The result indicates that when the air content of the concrete changes from 1 to 4 percent , the polarized resistance of the identical flow electricity time increases along with the increment of the air content , the corrosion current density reduces along with the increment of air content , the chloride ion diffusion coefficient reduces with the increment of air content ; when air content changes from 4 to 6 percent , the rule of the change of the polarized resistance and corrosion current density happens to be the opposite , the diffusion coefficient of the chloride ion increases along with the increment of air content ; when the air content is 4 percent , the rust - resisting property of concrete is best , and so is the impermeability of the concrete 試驗(yàn)結(jié)果表明,混凝土的含氣量在1 . 9 % ~ 4 . 2 %變化時(shí),極化電阻隨含氣量的增大而增大,腐蝕電流密度隨含氣量的增大而減小, cl -擴(kuò)散系數(shù)隨含氣量的增大而減小;當(dāng)含氣量在4 . 2 % ~ 6 . 4 %變化時(shí),極化電阻、腐蝕電流密度和cl -擴(kuò)散系數(shù)的變化規(guī)律則相反;當(dāng)含氣量為4 . 2 %時(shí),抗鋼筋銹蝕性能最佳,抗?jié)B性最好。 cl -擴(kuò)散系數(shù)與鋼筋銹蝕參數(shù)在一定程度上有著良好的相關(guān)性,抗?jié)B性的結(jié)果較好地反映了混凝土中鋼筋銹蝕的程度,可以用cl -擴(kuò)散系數(shù)評(píng)價(jià)引氣混凝土的抗鋼筋銹蝕性能。
