Solidified soil and preparation method thereof
The invention relates to the field of constructional engineering materials, and particularly discloses solidified soil and a preparation method thereof. The solidified soil comprises sludge and a solidifying component, and the solidifying component needing to be added in every 100 parts by weight of sludge comprises the following raw materials in parts by weight: 4-5 parts of Portland cement; 3-6 parts of granulated blast furnace slag; 0.3 to 0.5 part of low-calcium fly ash; 0.4 to 0.6 part of an alkali activator; 1-2 parts of an anti-dispersing agent; the anti-dispersing agent comprises soybean protein fibers, seven-hole fibers and a fine-hole silica gel desiccant according to the weight part ratio of 2: 2: 1; the preparation method comprises the following steps: preparing the raw materials of the curing component according to the ratio, and uniformly mixing; the sludge is homogenized, and the water content is controlled to be 100%; adding the curing component into the sludge, and uniformly stirring; and the curable sludge slurry is pumped through a pipeline, and scour pit covering and curing forming are completed. The stabilized soil provided by the invention has the properties of good dispersion resistance and good stabilized soil strength maintenance.
本申请涉及建筑工程材料领域，具体公开了一种固化土及其制备方法。固化土包括淤泥和固化组分，每100重量份的淤泥，需要添加的固化组分包括以下重量份的原料：硅酸盐水泥4～5份；粒化高炉矿渣3～6份；低钙粉煤灰0.3～0.5份；碱激发剂0.4～0.6份；抗分散剂1～2份；抗分散剂包括重量份之比为2：2：1的大豆蛋白纤维、七孔纤维和细孔硅胶干燥剂；其制备方法为：按照配比准备固化组分各原料，混合均匀；对淤泥均一化，并控制含水率100%；将固化组分添加到淤泥中搅拌均匀；管道泵送可固化淤泥浆体，完成冲刷坑覆盖，固化成型。本申请的固化土具有抗分散性好，固化土强度保持好的性能。
