摘要
文章筛选了有代表性的水泥、流化剂和高效不分散剂，采用水下不分散混凝土配制技术。配制出施工性能优良水下混凝土．在满足流动性、工作性能和力学性能的基础上．重点研究了水下混凝土的耐久性能．采用抗渗试验、氯离子电通量试验和氯离子扩散系数试验对水下混凝土的耐久性行了评价。研究结果表明：水下不分散混凝土强度、变形性能均满足要求．水下不分散混凝土的氯离子通电量均小于1000库仑．氯离子扩散系数小于3．0×10^-12m^2／s．耐久性能优良．该技术指标高于国内相关规范标准，满足技术和工程要求。
The paper filtrates representative sement,liquid agent and high efficency no separationagent,adopt no separation concrete mixture technology. Mixture construction performance choiceness concrete under water.on suiffice flowing and physics mechanics capability,workability base, emphases study concrete durability under water,adopting resistance seep test,chlorin ionelectricity flux＇test and chlorin ion pervasion coefficient test appraise concrete durability performance under water. As a study result： no separation concrete strengh under water, deformation capability satisfy required, chlorin ion electricity flux of no separation concrete under water less than 1000coulomb, chlorin ion pervasion less than 3.0×10^-12m^2/s, durability capability choiceness,technique guide line more than correlation home criterion, satisfy technique and engineering required.
