Self-repairing concrete, prefabricated embedded column core concrete composite column and preparation method
The invention discloses self-repairing concrete, a prefabricated embedded column core concrete composite column and a preparation method. The self-repairing concrete is microbial self-repairing concrete, which comprises, by volume percentage: concrete batching, a recycled coarse aggregate carrier and a Bacillus pasteurii bacteria solution; and the volume mixing amount of the recycled coarse aggregate carrier is 8%-12% of the total volume of the microbial self-repairing concrete, and the volume mixing amount of the Bacillus pasteurii bacteria solution is 30% of the total volume of the microbialself-repairing concrete. According to the invention, the prefabricated embedded column core concrete composite column adopts the microbial self-healing concrete for pouring specific parts, which canspecifically strengthen cracked parts of the concrete composite column, so that the using performance of the concrete composite column is improved; and a crack can be automatically repaired, and the service life is prolonged.
本发明公开了一种自修复混凝土、预制内嵌柱芯混凝土组合柱及制备方法，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、再生粗骨料载体和巴氏芽孢杆菌菌液组成；所述的再生粗骨料载体的体积掺量为微生物自修复混凝土总体积的8％～12％，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30％。本发明的预制内嵌柱芯混凝土组合柱，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，使得混凝土组合柱的使用性能提高，得到能够自动修复裂缝，并且使用寿命延长。
