摘要
分析当前淤泥固化土的应用现状,对不同淤泥土掺量的水泥砂浆进行抗压及抗折室内试验,研究淤泥土掺量及养护周期对水泥砂浆抗折抗压性能的影响规律。结果表明,随着龄期的增加,各淤泥土掺量的试样的抗折强度和抗压强度都逐渐提高,且趋于稳定,未掺入固化淤泥土的试样在全养护期内的强度均比其他试样要高;掺加固化淤泥土总体来讲对强度不利,5%含量淤泥土掺量条件下的强度最低,掺量继续提高时,试样的强度反而略微增大。
Based on the analysis of the current application status of silt-solidified soil,laboratory tests on compressive and flexural resistance of cement mortar with different silt and soil contents were carried out to study the law of the influence of silt and soil content and curing period on the flexural and compressive resistance of cement mortar.The results showed that as the age increased,the flexural strength and compressive strength of the samples under different dosages gradually increased and tended to stabilize.The strength of the samples without solidified silt added was higher than that of other samples throughout the entire curing period;Adding solidified silt soil is generally detrimental to strength,with the lowest strength under the condition of a 5%silt soil content.When the content continues to increase,the strength of the sample slightly increases.
