摘要和关键词

摘要: 文章针对某新型大直径混凝土管桩基础最外层的护壁材料, 设计水下不分散砂浆试验, 该材料对于流动性、抗分散性均有较高的要求, 且没有相关公式供参考; 采用矿物掺合料单掺试验, 同时设计全因子实验, 测试灌浆料的流动度、扩展度、pH值和浊度, 研究矿物掺合料对灌浆料流动性和抗分散性的影响以及各掺合料之间的交互效应; 采用Minitab软件进行数据分析与拟合, 基于双响应预测结果, 获得水下不分散灌浆料的最佳掺量分别为粉煤灰掺量5%、矿粉掺量15%、偏高岭土掺量15%, 并给出浊度与流动性相应的拟合公式。该研究为矿物掺合料复掺调节灌浆料的流动性与抗分散性提供了参考。

Abstract and Keywords

Abstract: Aiming at the outermost wall material of a new large-diameter concrete pipe pile foundation, an underwater non-dispersible mortar test was designed. The material has high requirements for fluidity and dispersion resistance, and there is no relevant formula for reference. In this paper, the single admixture test of mineral admixtures and the full factorial experiment were designed to test the fluidity, expansion, pH value and turbidity of grouts, and the influence of mineral admixtures on the fluidity and dispersion resistance of grouts and the interaction effect between each admixture were studied. Minitab software was used for data analysis and fitting, and based on the prediction results of double response, the optimal content of underwater non-dispersible grouts was determined as 5% fly ash, 15% mineral powder and 15% metakaolin, and the fitting formula corresponding to turbidity and fluidity was given. The study provides a reference for adjusting the fluidity and dispersion resistance of grouts using compound mineral admixtures.

Keywords: dispersion resistance; fluidity; underwater non-dispersible grouts; slag; fly ash; metakaolin; silica fume
