一种利用芽孢杆菌H4提高再生骨料性能的方法
摘要：
本发明属于混凝土技术领域，提供一种利用芽孢杆菌H4提高再生骨料性能的方法，包括以下步骤：(1)将芽孢杆菌H4与矿化培养液混合，得到混合培养液；所述芽孢杆菌H4的保藏编号为CGMCC NO.9629；(2)将再生骨料在所述步骤(1)得到的混合培养液中浸泡，得强化再生骨料。采用本发明提供的制备方法，得到的强化再生骨料吸水率为4.52～15.92％，与微生物处理前相比，吸水率降低了18.6～25％；所得强化再生骨料制备为再生砂浆后，再生砂浆的抗压强度增加8.9～25.3％。
摘要（英）：

The invention belongs to the technical field of concrete and provides a method for improving performance of recycled aggregate by utilizing bacillus H4. The method comprises the following steps: (1) mixing bacillus H4 and a mineralized culture solution so as to obtain a mixed culture solution, wherein the bacillus H4 has a collection number of CGMCC NO. 9629; (2) soaking the recycled aggregate inthe mixed culture solution obtained in the step (1), thereby obtaining the reinforced recycled aggregate. According to the preparation method provided by the invention, the prepared reinforced recycled aggregate has a water absorption rate of 4.52-15.92%. Compared with the method before microbiological treatment, the method disclosed by the invention has the advantages that the water absorption rate is reduced by 18.6-25%; after recycled mortar is prepared from the reinforced recycled aggregate, the compressive strength of the recycled mortar is increased by 8.9-25.3%.
