摘　　要：为提高泡沫混凝土性能,文中先通过正交试验,选取不同类型起泡剂、稀释倍率、不同类型稳泡剂及掺量、发泡用水温度为研究对象,获得稳定的气-液发泡体系;再进行不同掺量的纳米颗粒复配试验,获得最佳复配发泡方案,进而研究它对泡沫混凝土性能的影响。研究结果表明,掺量为0.5%的纳米固体颗粒与稳泡剂结合掺拌,可提升泡沫性能,并有效改善了泡沫混凝土的力学性能和保温性能,为寒区道路工程应用泡沫混凝土提供参考依据。To improve the performance of foam concrete,the study first conducted orthogonal experiments focusing on different types of foaming agents,dilution ratios,types and dosages of stabilizing agents,and foaming water temperatures to establish a stable gas-liquid foaming system.Subsequently,experiments with varying dosages of nano-particles were carried out to identify the optimal composite foaming scheme,followed by an investigation of its effects on the performance of foam concrete.The results indicate that incorporating 0.5%nano solid particles combined with stabilizing agents enhances the foam properties and significantly improves the mechanical and thermal insulation properties of foam concrete.This research provides a reference for the application of foam concrete in cold-region road engineering.
