Reinforcing method of recycled concrete
The invention discloses a reinforcing method of recycled concrete, and belongs to the technical field of biology, the reinforcing method comprises the following steps: preparing a culture medium; inoculating and culturing: inoculating a bacillus pasteurii seed solution into the culture medium, and culturing at a constant temperature of 30 DEG C and a stirring speed of 180rpm; introducing compressed air for aerobic culture, and obtaining a bacillus pasteurii culture solution; Mineralization reinforcing: the concrete regeneration particles are soaked in a diluted bacillus pasteurii culture solution for 1-3 h, then mineralization treatment is conducted, in the mineralization process, the bacillus pasteurii culture solution is circulated through a feed liquid pump, urea and calcium nitrate are added at the same time, and therefore a mineralization solution with the concentration of the urea and the concentration of the calcium nitrate being 0.6-0.9 mol/L is obtained, and the temperature of the mineralization solution is 25-30 DEG C; and drying: drying the mineralized solution to obtain regenerated mineralized particles with the water content of 8-9%. The method has the advantages of continuous culture, simple process and better reinforcing effect.
本发明公开了一种再生混凝土的强化方法,属于生物技术领域,该强化方法包括以下步骤:配制培养基;接种培养:将巴氏芽孢杆菌种子液接入培养基中,在30℃、搅拌转速180rpm下恒温培养;通入压缩空气好氧培养,得到巴氏芽孢杆菌培养液;矿化强化:将混凝土再生颗粒通过稀释后的巴氏芽孢杆菌培养液浸泡1‑3h,然后进行矿化处理,矿化过程中,通过料液泵循环巴氏芽孢杆菌培养液,同时加入尿素和硝酸钙,从而得到含尿素和硝酸钙浓度均为0.6‑0.9mol/L的矿化溶液,矿化溶液温度为25‑30℃;烘干:将矿化溶液进行烘干处理,得到含水率为8‑9%的再生矿化颗粒。本发明具有可连续培养、工艺简单、强化效果较好的优点。
