Waste-utilizing and carbon-reducing low-cement-content fluid-state solidified soil and preparation method thereof
The invention discloses low-cement-content fluid-state solidified soil capable of utilizing waste and reducing carbon and a preparation method of the low-cement-content fluid-state solidified soil. The fluidized stabilized soil is prepared from the following components: 100 to 110 parts of fine-grained soil, 10 to 13 parts of cement, 2 to 5 parts of fly ash, 0.5 to 1 part of semi-hydrated gypsum, 0.5 to 2 parts of polyurethane, 0 to 0.5 part of a water reducing agent and 35 to 45 parts of water. Wherein the weight ratio of the fine-grained soil to the cement is (9-10): 1. The preparation method comprises the following steps: S1, determining the proportion of the fluid-state solidified soil according to the requirements of fluidity, slump and strength required by engineering; s2, polyurethane and semi-hydrated gypsum are weighed in advance according to the proportion and mixed, and a mixture A is obtained; s3, obtaining a mixture B; s4, adding water and uniformly mixing to form flow-state solidified soil; and S5, the flow-state solidified soil is pumped to an application area. According to the present invention, the cement consumption is significantly reduced, the resource reutilization of the waste is achieved, the carbon reduction purpose is achieved, and in the subsequent maintenance period, the cementation acting force between the soil particles can be further enhanced, and the compressive strength can be improved.
本发明公开了一种利废降碳的低水泥掺量流态固化土及其制备方法。上述流态固化土具有以下组分：细粒土100~110份、水泥10~13份、粉煤灰2~5份、半水石膏0.5~1份、聚氨酯0.5~2份、减水剂0~0.5份、水35~45份。其中，所述细粒土和水泥的重量份配比为9~10：1。所述制备方法包括以下步骤：S1根据工程所需的流动度、坍落度和强度要求，确定流态固化土的配比；S2根据配比预先称取聚氨酯和半水石膏进行拌合，得到拌合物A；S3得到拌合物B；S4加水拌合均匀形成流态固化土；S5将流态固化土泵送至应用区域。本发明显著降低了水泥的用量，实现废物的资源化再利用并达到降碳目的，此外，在后续的养护期间，可进一步增强土颗粒之间的胶结作用力，提高抗压强度。
