Preparation method of concrete self-healing rigid waterproof material
The invention relates to a concrete waterproof material, in particular to a preparation method of a concrete self-healing rigid waterproof material. The material comprises the following components: a cement base material, silica powder, a polymer modifier, steel fibers, a magnesium oxide microcapsule self-healing agent and a waterproof additive. The preparation method comprises the following steps: weighing the cement base material and the silica powder in parts by weight, and mixing the cement base material and the silica powder to obtain a mixture; 2, sequentially weighing the polymer modifier, the steel fiber, the magnesium oxide microcapsule self-healing agent and the waterproof additive in parts by weight, sequentially adding the components into the mixture obtained in the step 1 according to the weighing sequence, and fully stirring to obtain a mixture; and 4, pouring the mixture obtained in the step 2 into a mold, and carrying out proper maintenance after the mixture is preliminarily cured. The silica powder, the polymer modifier, the steel fibers, the microcapsule self-healing agent and the waterproof additive cooperate with one another, so that the probability that the concrete cracks is reduced, and the waterproof performance of the concrete is improved.
本申请涉及一种混凝土防水材料，具体涉及一种混凝土自愈合刚性防水材料的制备方法。该材料包括如下组分：水泥基材、硅石粉、聚合物改性剂、钢纤维、氧化镁微胶囊自愈剂、防水添加剂；其制备方法包括如下步骤：按重量份称取水泥基材和硅石粉，并将二者混合，得到混合物；按重量份依次称取聚合物改性剂、钢纤维、氧化镁微胶囊自愈剂、防水添加剂，并按称取顺序依次将上述组分加入至步骤一的混合物中，并充分搅拌，得到混合物；将步骤二中的混合物浇筑至模具中，待其初步固化后，进行适当的养护。本申请通过硅石粉、聚合物改性剂、钢纤维、微胶囊自愈合剂和防水添加剂协同配合，降低了混凝土产生裂纹的几率，增加了混凝土的防水性能。
