High-strength waterproof foam light soil and preparation method thereof
The invention relates to the field of concrete, and particularly discloses high-strength waterproof foam light soil and a preparation method thereof. The light soil comprises river bottom silt, cement, an admixture, nano boron fibers, nano PMMA microspheres, tert-butyl acrylate, a foaming agent and water. The preparation method comprises the following steps: mixing the river bottom sludge, the cement, the admixture, the nano boron fibers and 70% of water to obtain a first mixture, and mixing the nano PMMA fibers and tert-butyl acrylate to obtain a second mixture; diluting a foaming agent with water, then mixing the diluted foaming agent with the first mixture and the second mixture, pouring, standing for maintenance, and forming to obtain the foamed light soil. The nano boron fibers and the nano PMMA microspheres are utilized to enhance the strength of the light soil, and tert-butyl acrylate is utilized to improve the waterproofness of the light soil, thereby widening the application range of the light soil.
本申请涉及混凝土的领域，具体公开了一种高强度防水型泡沫轻质土及其制备方法。轻质土包括河底淤泥、水泥、外掺料、纳米硼纤维、纳米PMMA微球、丙烯酸叔丁酯、发泡剂、水；其制备方法为：将河底淤泥、水泥、外掺料、纳米硼纤维和70%的水混合，即得第一混料，将纳米PMMA纤维和丙烯酸叔丁酯混合，即得第二混料；将发泡剂用水稀释，随后与第一混料和第二混料混合，浇筑并静置养护，成型后即得泡沫轻质土。本申请利用纳米硼纤维和纳米PMMA微球提高轻质土的强度，同时利用丙烯酸叔丁酯改善轻质土的防水性，扩大轻质土的应用范围。
