Self-repairing concrete, profile steel recycled aggregate concrete bearing column and preparation method
The invention discloses self-repairing concrete, a profile steel recycled aggregate concrete bearing column and a preparation method; the self-repairing concrete is microorganism self-repairing concrete and comprises concrete ingredients, a recycled coarse aggregate carrier and bacillus pasteurii liquid by volume percentage; the volume mixing amount of the recycled coarse aggregate carrier is 9-11% 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 profile steel recycled aggregate concrete bearing column, different cracks generated by a concrete bearing column in an existing profile steel-concrete bearing column under different loads can be automatically repaired, the pressure resistance of a bearing column component is improved, the bearing performance and durability of a building structure are improved, and structural safetyis guaranteed.
本发明公开了一种自修复混凝土、型钢再生骨料混凝土承重柱及制备方法，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9％～11％，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％。本发明的型钢再生骨料混凝土承重柱，可以自行修复以往型钢‑混凝土承重柱中混凝土承重柱在不同荷载下所产生的不同的裂缝，提高了承重柱构件抵抗压力的能力，提高建筑结构承载性能和耐久性，保证了结构安全。
