Preparation method of concrete crack self-repairing particles
The invention relates to the field of concrete processing, and particularly discloses a preparation method of concrete crack self-repairing particles. Comprising the following steps: S1, activating bacillus pasteurii to obtain a bacterial suspension; s2, placing the adsorption particle modified fiber in a bacterial suspension for adsorption treatment to obtain a load material; and S3, uniformly spraying alkyd resin liquid on the surface of the load material, drying and dispersing to obtain a finished product. When new micro-crack damage is generated in the use process of the concrete, the microorganisms play a self-repairing role to fill cracks in the concrete, so that the strength of the concrete is maintained, the service life of the concrete is prolonged, and the durability of the concrete is improved.
本申请涉及混凝土加工领域，具体公开了一种混凝土裂缝自修复颗粒的制备方法；包括如下步骤：S1、将巴氏芽孢杆菌活化，得到菌悬液；S2、将吸附颗粒改性纤维置于菌悬液中吸附处理，得到负载料；S3、在负载料表面均匀喷涂醇酸树脂液，经干燥、分散，制得成品；在混凝土使用过程中产生新的微裂缝损伤时，微生物发挥自修复作用，对混凝土内部裂缝进行填充，保持混凝土强度，延长混凝土的使用寿命和耐久性。
