Construction method for reducing springback based on low-alkalinity cement spraying vegetation concrete
The invention discloses a construction method for reducing springback based on low-alkalinity cement spraying vegetation concrete, which comprises the following steps: spraying an interface treatment layer on a spraying surface, and then spraying vegetation porous concrete, the vegetation porous concrete is prepared from the following raw materials: aggregate, low-alkalinity cement, water, a thickening agent with a fertilizer loading function, a thixotropic agent, a water reducing agent, synthetic fibers, a polymer emulsion and an accelerator, and the relationship between the concrete and an interface can be increased through an interface treatment process, so that the adhesion and the interface bonding performance of the concrete are improved; and meanwhile, the technical problems of high internal alkalinity, lack of nutrient substances, poor spraying performance, insufficient deformation performance and the like of sprayed plant-growing concrete can be solved. The sprayed vegetation concrete not only can load fertilizer to provide nutrients for subsequent plant growth, but also can adjust the internal alkalinity of the concrete, and does not influence cement hydration.
本发明公开一种基于低碱度水泥喷射植生混凝土降低回弹施工方法，包括以下步骤：先在喷射面上喷涂界面处置层，再喷射植生多孔混凝土,所述植生多孔混凝土原料包括骨料、低碱度水泥、水、具有肥料负载功能的增稠剂、触变剂、减水剂、合成纤维、聚合物乳液、速凝剂，不仅可以通过界面处置工艺来增加混凝土与界面之间的联系，从而提高其粘附性和界面粘接性能，同时还能解决喷射植生混凝土存在的内部碱性大，营养物质缺乏，喷射性能不佳以及变形性能不足等技术问题。所喷射的植生混凝土不仅可以负载肥料为后续植物生长提供养分，还可以调节混凝土内部碱度，并不会对水泥水化产生影响。
