摘要
袋装水泥土是一种新型的砌筑材料.针对一2160 mm×1000 mm×2250 mm挡土墙的袋装水泥土试块进行了一系列的实验研究,对挡土墙中的袋装水泥土试块在不同龄期、不同堆积荷载、浸泡与不浸泡的条件下的无侧限抗压强度进行了对比分析;讨论了模型袋、堆积荷载、龄期、浸泡对袋装水泥土的无侧限抗压强度的影响,以及同条件下不同龄期和不同堆积荷载下的袋装水泥土的强度关系式,以及相同配比、相同龄期的袋装水泥土在浸泡后与浸泡前强度比值,为其用于实际工程提供了实验依据.
Sacked cemented - soil is a kind of new building material. A series of experiment had been carried out about sacked cemented - soil examination of a 2 160 mm ×1 000 mm ×2 250 mm test parapet. This article analyzes the unconfined compressive strength of sacked cemented - soil in parapet under the condition of different curing time, different accumulated load and being soaked or not. It also discusses the influence of the unconfined compressive strength that produced by model - bag, accumulated load,age curing time and soak. It got the conclusion that the strength RDS of the sacked cemented - soil with different curing time and the strength RDS of the sacked cemented - soil with different accumulated load in the same condition. It also got the ratio of the unconfined compressive strength between soaked and without soaked. The whole study provides experimental foundations for its use in practice.
