注浆法是地下水害治理的主要方法,而浆液的黏度时变特性是注浆治理的关键因素,因此浆液黏度时变特性研究十分必要.针对地下工程动水注浆中常用的2种速凝浆液,水泥–水玻璃浆液和高聚物改性水泥浆液,开展室内试验并对试验数据进行拟合分析.采用振动式黏度计测试其黏度时变性和反应温度变化,分析2种材料在不同水灰比和不同混合体积比下的黏度和温度时变特性,根据黏度时变特性将浆液反应过程划分为3个阶段,并分析不同阶段的黏度特性,对数据进行分析得到不同水泥浆水灰比和不同浆液混合体积比下的黏度时变方程,在此基础上得出速凝注浆材料的适用性.

Viscosity of grouts is an important factor in grouting which is the main method in groundwater governance. Research on time-dependent behavior of viscosity is very necessary. Laboratory tests were performed and the data was analyzed. Viscosity and temperature were measured using vibrating type viscometer for two fast curing grouts,cement-sodium silicate and polymer modified cement grout. Variation of viscosity and temperature with different water-cement ratios and volume mixing ratios of the grouts were analyzed. Reaction progress was classified to three periods according for viscosity behavior. Data fitting was done with viscosity of grouts measured,and equations of time-dependent viscosity were obtained. Adapation of different fast curing grouts was discussed.
