Anticorrosive concrete grouting material for coastal structure connection and preparation method thereof
The invention relates to an anticorrosive concrete grouting material for coastal structure connection and a preparation method thereof, and belongs to the technical field of coastal assembly structureconnecting piece corrosion prevention. The grouting material comprises the following components: expansible compound cement, slag sand, fly ash (FA), polyvinyl alcohol (PVA) (containing an oxidizingagent and a catalyst), graphene oxide (GO), a water reducing agent, a thickening time control agent, a defoaming agent, a mineral admixture and water. The shrinkage-free efficiency of the grouting material is realized through GO-PVA hydrogel internal curing, compound cement micro-expansion and FA shrinkage reduction effects; the energy storage effect of the GO-PVA hydrogel microcapacitor is exerted to avoid formation of a steel bar corrosion microbattery in a grouting material sleeve, the steel bar corrosion self-immune efficiency is achieved, the seawater corrosion resistance of the groutingmaterial is improved by exerting slag sand, and the anticorrosive concrete grouting material has huge economic and environment-friendly benefits in the field of quick connection of coastal assembly structures.
本发明涉及滨海结构连接用防腐型混凝土灌浆料及制备方法，属于滨海装配结构连接件防腐技术领域。该灌浆料包括以下组分：膨胀性复配水泥、矿渣砂、粉煤灰(FA)、聚乙烯醇(PVA)(含氧化剂、催化剂)、氧化石墨烯(GO)、减水剂、调凝剂、消泡剂、矿物掺合料和水。通过GO‑PVA水凝胶内养护、复配水泥微膨胀及FA减缩效应实现灌浆料无收缩效能；发挥GO‑PVA水凝胶微电容器储能效应规避灌浆料套筒中钢筋腐蚀微电池的形成，实现钢筋腐蚀自免疫效能，发挥矿渣砂提升灌浆料耐海水侵蚀能力，在滨海装配结构快速连接领域蕴含着巨大的经济和环保效益。
