摘要
无机注浆材料具有与水快速凝固、有一定强度等优点。配置了3种不同水、无机注浆料、黏土比例的固化体试样,进行了1 d, 3 d, 7 d, 14 d, 28 d龄期的直剪试验与无侧限抗压强度试验,获得了固化体强度与龄期、水灰比的关系。试验结果为该材料用于堤坝抢险加固等提供了基础性参考。
Inorganic grouting material has the advantages of quick-setting with water and certain strength.Three samples with different proportions of water,grouting material and clay were prepared for direct-shear tests at the age of 1d,3 d,7 d,14 d and 28 d.The relationship between the strength of solidified body and age,water cement ratio was obtained.The test results provide a basic reference for the application of this material in dam reinforcement.
