In-situ foamed light sludge solidified soil and preparation method and foaming agent thereof
The invention discloses in-situ foamed light sludge solidified soil as well as a preparation method and a foaming agent thereof, and belongs to the technical field of solidified soil materials. The in-situ chemical foaming agent for the light sludge solidified soil comprises metal aluminum powder and non-metal compound composite particles/powder, aluminum powder particles are separated through non-metal compound particles, and the median particle size of the metal aluminum powder and the non-metal compound particles is smaller than or equal to 5 micrometers. Metal aluminum powder and non-metal compound composite particles/powder are used as in-situ chemical foaming agents and used for preparing the light sludge solidified soil, aluminum powder particles are fully separated by non-metal compounds through superfine grinding, and the light sludge solidified soil is prepared by means of the separation effect of the non-metal compound particles. Therefore, small air holes can be generated through in-situ foaming, and the uniformity of the size of the air holes is ensured; and meanwhile, the agglomeration phenomenon of the aluminum powder after meeting water can be effectively avoided, and overlarge bubbles formed by air hole communication are avoided, so that the strength of the obtained light sludge solidified soil is ensured.
本发明公开了一种原位发泡轻质淤泥固化土及其制备方法和发泡剂，属于固化土材料技术领域。本发明的轻质淤泥固化土用原位化学发泡剂，包含金属铝粉、非金属化合物复合颗粒/粉末，铝粉颗粒之间通过非金属化合物颗粒分离开来，且金属铝粉与非金属化合物颗粒的中位粒径≤5μm。本发明以金属铝粉、非金属化合物复合颗粒/粉末作为原位化学发泡剂，用于轻质淤泥固化土的制备，经超细研磨使得铝粉颗粒之间被非金属化合物充分分离开来，借助于非金属化合物颗粒的分离作用，从而保证经原位发泡可以生成得到较小的气孔并保证气孔尺寸的均匀性；同时还可以有效避免铝粉遇水后发生团聚现象，避免气孔串通形成过大气泡，因而保证所得轻质淤泥固化土的强度。
