摘要
通过对掺入不同尺寸纤维(聚乙烯醇)、不同土壤固化剂、不同聚合物(冷溶聚乙烯醇)以及是否掺入熟石灰等材料的试件分别进行强度试验和耐久性试验,得到了一种最优配合比。结果表明,在适当的配合比下,纤维复合泥的强度和耐久性较生土有了显著的提升,同时该种加固材料的外观颜色接近于生土墙体,是一种理想的对现存民居进行加固的材料。
In this paper, the strength test and durability test were carried out by adding different sizes of fibers (polyvinyl alcohol), different soil solidifying agents, different polymers (cold-soluble polyvinyl alcohol) and whether or not to mix with hydrated lime, and an optimum proportion was obtained. The test results show that the strength and durability of the fiber composite mud are significantly improved compared with that of the native soil at the appropriate proportion. At the same time, the appearance color of the material is close to that of the raw soil wall, and it is an ideal material for strengthening the existing residential buildings.
