Four key technologies for foam lightweight soil foaming

Summarising the various aspects of the cast-in-place foam lightweight soil process, the common point lies in the mixing, which is reflected in the mixing characteristics of a multi-phase medium, multi-step and multi-ratio. The mixing of each link is respectively:

　　(1) foaming agent dilution: The foaming agent dilution link is based on the dilution rate of the foaming agent will be diluted into the foaming liquid, in order to facilitate the accurate process of accurate measurement. The mixing of this link is manifested as the mixing of the blowing agent and dilution water.
　　(2) Cement slurry mixing: The cement slurry mixing process is actually the mixing reaction process of cement and water, which is controlled by cement slurry proportion and mixing time.
　　(3) Foam preparation: Foam preparation is the process of mixing foaming liquid and compressed air. Compressed air and foaming liquid are mixed in the foaming device, and the foaming liquid and compressed air delivery power serve as the driving force to form a certain foam flow. The mixing ratio of the link is determined by the foaming agent’s foaming multiplier or the standard density value of the foam. As the mixing medium is gas-liquid mixing, its control is difficult, and its quality is determined by the foaming technology of the equipment system and the performance of the foaming agent, which is manifested in whether the prepared foam flows delicate and whether the foam density is stable.
　　(4) Mixing of foam and cement paste: the mixing ratio of this process is determined by the target value of wet density of foam lightweight soil or the bubble rate of lightweight soil. The control of this link is the most difficult to control because it contains gas, liquid and solid three-phase media; its control quality is determined by the mixing technology of the equipment system, which is manifested in whether the density of the prepared foam lightweight soil is stable and uniform.
