Abbreviation of erosion resistance sulfate preservatives. Execution standard: JC/T1011-2006 一、混凝土抗盐类侵蚀防腐剂适用范围 First, erosion resistance of concrete scope sulphate preservatives 1、在硅盐类水泥砂浆或混凝土中掺加一定的抗盐类侵蚀防腐剂，能抵抗环境中一定浓度的SO2-4、Cl-、HCO-3、CO2、NH-4、Mg2+以及其它盐类、泛类的地下水、地表水、海水、污水和含盐土壤、可溶岩盐等侵蚀性物对砂浆或混凝土的侵蚀。 1，in aluminum-silicate cement mortar and concrete adding amount of sulphate class erosion resistance preservatives, can resist environment certain concentration of SO2-4,Cl-, HCO-3, CO2，NH-4, Mg2+ and other salts, pantothenic acid kind of surface water and groundwater, sea water, sewage and saline soil, can lavas salt and so on mortar or erosive substance of concrete erosion. 2、在硅盐类水泥砂浆或混凝土中掺加一定的抗盐类侵蚀防腐剂，可用于受环境侵蚀的海港、水利、污水、地下、隧道、引水、道路、桥梁、工和民用建筑础等工程。 2, the aluminum-silicate cement mortar and concrete adding amount of sulphate class erosion resistance can be used by environmental preservatives, erosion seaport, water conservancy, sewage, underground, tunnels, water diversion and roads, Bridges, industrial and civil building foundation and other projects. 二、掺：按水泥6～12%。 Second, according to the quality of the cement admixture: 6～12%. 三、抗盐类侵蚀防腐剂理化性能 Three, resistance to erosion preservatives physico-chemical properties of sulfate 抗盐类侵蚀防腐剂理化性能要求 Resistance to erosion preservatives physical-chemical properties of sulphate class requirements 项目 | 标准指标 | 实测值 | 化学成分 | 氧化镁/% | ≤5.0 | 2.3 | 氯离子/% | ≤0.05 | 0.01 | 物理性能 | 比表面积/（㎡/㎏） | ≥300 | 375 | 凝结时间 | 初凝/min | ≥45 | 60 | 终凝/h | ≤10 | 8 | 抗压强度比/% | 7d | ≥90 | 96 | 28d | ≥100 | 105 | 膨胀率/% | 1d | ≥0.05 | 0.07 | 28d | ≤0.60 | 0.54 | 抗侵蚀性 | 抗蚀系数（K） | ≥0.85 | 0.88 | 膨胀系数（E） | ≤1.50 | 1.3 |
海水或盐碱地区环境水中的盐和镁盐，对水泥混凝土具有化学腐蚀破坏作用，氯盐和盐还对混凝土中的钢筋具有锈蚀破坏作用，所以混凝土必须采取防腐措施。 Seawater or saline environment water sulfates and magnesium salts, of cement concrete with chemical corrosion damage, chlorine salt and sulphate also in reinforced concrete with corrosion damage, so concrete must take anticorrosion measures. BT-7007型混凝土防腐蚀剂是由表面活性剂、无机盐、有机助剂和载体配制而成的外加剂。在普通硅盐水泥中同时掺加防腐蚀剂和Ⅱ级粉煤灰，可使水泥的抗盐极限浓度（K值）提高到10000～15000mg/l，较普通抗盐水泥高4～6倍。防腐蚀剂还具有防止钢筋锈蚀，改善抗冻融性能，提高抗渗性和增加强度等作用，适用于沿海铁路、港口及盐碱地区耐中、强盐侵蚀混凝土的施工。 BT-7007 occupationally exed type concrete antifushiji is by surfactant, inorganic salt, organic fertilizer and carrier made from the admixtures. In ordinary Portland cement simultaneously adding antifushiji andⅡgrade fly ash, can make cement resistance sulfate limit concentration (K) values increase to 10,000～15000mg/l, high resistance than ordinary cement sulfate 4～6 times. Antifushiji still is had prevent corrosion of reinforcement, improving freezing-thawing resisting performance and improve penetration-proof quality and increase the intensity effects, and suitable for coastal railway, port and saline, strong erosion resistance of concrete construction sulfates. 一、应用范围 A，the application scope BT-7007型适用于水下或冻线以下础工程防腐蚀混凝土及适用于有抗冻融要求的防腐蚀混凝土。 BT-7007 occupationally exed type applies to underwater or frozen line the following basic engineering anti-corrosion of concrete and suitable for freezing-thawing resisting requirements of anti-corrosion concrete. 二、主要技术指标 Second, the technical indexes 技术性能 | 试验方法标准 | 试验项目 | 指标 | 耐腐蚀性 | GB749-65 | 抗盐极限浓度（K值） | 10000～15000 | 防锈蚀性 | YBJ231-91 | 电化学综合评定法 | 合格 | 抗冻融性 | GBJ82-85 | 相对动弹性模（P） | ＞60% | 重损失率（ΔW） | ＜5% | 减水率 | GB8076-03 | 混凝土减水率 | ＞10% | 抗压强度比 | ＞ |
三、使用方法 Three, using method 1、BT-7007型防腐蚀剂应与粉煤灰同时掺入混凝土中，并按TB201-86附录13和《粉煤灰防腐蚀混凝土施工技术暂行规定》施工； 1, BT-7007 occupationally exed type antifushiji should simultaneously with fly ash in concrete mixing, and according to TB201-86 appendix 13 and the fly ash concrete construction technology anti-corrosion provisional regulations construction; 2、防腐蚀剂掺为水泥与粉煤灰总重的2～2.5%； 2，antifushiji for cement and admixture of fly ash total weight of 2～2.5%; 3、BT-7007型防腐蚀剂不燃、无，属非危险品，但不得入口，有效保存期为3年。 3, BT-7007 occupationally exed type antifushiji noncombustible, non-toxic, belong to the dangerous goods, but not entrance, effective duration for 3 years.
