Concrete self-repairing material, and preparation method thereof and concrete with concrete self-repairing material
The invention relates to the field of building materials, and particularly discloses a concrete self-repairing material, and a preparation method thereof and concrete with the concrete self-repairing material. The concrete self-repairing material comprises a porous matrix inner core, the porous matrix inner core forms a porous structure inorganic particle, the porous structure inorganic particle is provided with a plurality of mutually communicated loading pore channels, and microorganisms are loaded in the loading pore channels; and the anti-loss coating shell is arranged on the surface of the porous matrix inner core so as to isolate the microorganisms from the external environment. According to the concrete material, inorganic particles of a porous structure serve as an inner core, the surface of the inner core is coated with a shell, mineral ions in seawater form minerals under the action of microorganisms, self-repairing of the concrete material is completed, meanwhile, the core-shell structure is adopted for preventing corrosion substances from invading, and the engineering durability and the service life of concrete preparation are improved.
本申请涉及建筑材料领域，具体公开了一种混凝土自修复材料及其制备方法和具有其的混凝土。混凝土自修复材料包括：多孔基体内核，所述多孔基体内核形成为多孔结构无机颗粒，所述多孔结构无机颗粒上设有若干相互贯通的负载孔道，所述负载孔道内负载有微生物；抗流失包覆外壳，所述抗流失包覆外壳设于所述多孔基体内核表面以隔离所述微生物与外界环境。本申请将该混凝土材料以多孔结构的无机颗粒为内核，在其内核表面包覆外壳，通过海水中的矿物离子在微生物作用下形成矿物，完成对混凝土材料的自修复，同时本申请方案采用核壳结构阻止腐蚀物质的侵入，提升了混凝土制备的工程耐久性和服役寿命。
