Preparation method of fiber reinforced composite curing agent for reinforcing sludge
The invention relates to the technical field of sludge reinforcement, and discloses a preparation method of a fiber reinforced composite curing agent for sludge reinforcement, which comprises the following preparation steps: 1) respectively airing and drying carbide slag and desulfurized gypsum; 2) grinding and mixing the dried carbide slag and desulfurized gypsum to form a ground material; 3) stirring and mixing the ground material with slag, fly ash and glass fiber to form a fiber reinforced composite curing agent; the glass fibers are randomly interspersed in the solidified soil to form a three-dimensional network after being doped into the sludge, and deformation and damage of the soil body are hindered or delayed through the excellent tensile and pulling resistance of the glass fibers; when the soil body deforms under the action of external force, the glass fibers prevent the development and extension of cracks and enhance the deformation resistance of the soil body by exerting the interface friction force, so that the failure mode is changed, and the problem of brittle failure of the sludge solidified soil is solved.
本发明涉及加固淤泥的技术领域，公开了加固淤泥的纤维加筋复合固化剂制备方法，包括以下制备步骤：1)、将电石渣以及脱硫石膏分别进行晾晒烘干；2)、将烘干后的电石渣以及脱硫石膏进行研磨混合，形成研磨料；3)、将研磨料与矿渣、粉煤灰以及玻璃纤维进行搅拌混合，形成纤维加筋复合固化剂；玻璃纤维掺入淤泥后在固化土中随机穿插形成三维网络，通过玻璃纤维自身优良的抗拉和抗拔性能阻碍或延缓了土体的变形破坏；当土体受外力发生变形时，玻璃纤维通过发挥界面摩擦力，阻止了裂缝的发展与延伸，增强了土体抵抗变形的能力，进而改变了破坏模式，解决了淤泥固化土存在脆性破坏的问题。
