Self-repairing concrete, prefabricated recycled aggregate concrete composite floor slab and preparation method
The invention discloses self-repairing concrete, a prefabricated recycled aggregate concrete composite floor slab and a preparation method. The self-repairing concrete is microorganism self-repairingconcrete, and the self-repairing concrete is composed of concrete ingredients, recycled aggregate and bacillus pasteurii liquid by volume percentage, wherein the volume mixing amount of the recycled aggregate is 15%-45% of the total volume of the microbial self-repairing concrete, and the volume mixing amount of the bacillus pasteurii liquid is 40%-50% of the total volume of the microbial self-repairing concrete. According to the prefabricated recycled aggregate concrete composite floor slab, microbial self-repairing concrete is poured into specific parts, the cracked parts of a concrete composite column can be reinforced in a targeted mode, the use performance of the composite floor slab is improved, cracks can be automatically repaired, and the service life is prolonged.
本发明公开了一种自修复混凝土、预制再生骨料混凝土组合楼板及制备方法，所述的自修复混凝土为微生物自修复混凝土，按体积百分比计，由混凝土配料、再生骨料和巴氏芽孢杆菌菌液组成；所述的再生骨料的体积掺量为微生物自修复混凝土总体积的15％～45％，巴氏芽孢杆菌菌液的体积掺量为微生物自修复混凝土总体积的40％～50％。本发明的预制再生骨料混凝土组合楼板，采用微生物自修复混凝土进行特定部位的浇筑，可以针对性的对混凝土组合柱开裂的部位进行加固，使得组合楼板的使用性能提高，得到能够自动修复裂缝，并且使用寿命延长。
