The invention relates to a concrete waterproof compacting agent and a preparation method thereof. The concrete waterproof compacting agent is prepared by taking inorganic aluminum, mineral fibers, a surfactant, sodium silicate and water as raw materials according to a proper proportion, during preparation, dispersing the inorganic aluminum in the water under the heating condition, then adding themineral fibers, carrying out uniform stirring, so that the concrete waterproof compacting agent is obtained, cooling, adding a surfactant, stirring and mixing, finally adjusting the pH value, adding sodium silicate, and stirring to finally obtain the concrete waterproof compacting agent. When the waterproof compacting agent is applied to concrete, the impermeability can be remarkably improved, concrete shrinkage can be reduced, concrete cracking can be prevented, water permeation can be effectively prevented, and meanwhile the concrete strength can be remarkably improved.
本发明涉及一种混凝土防水密实剂及其制备方法，所述混凝土防水密实剂通过以无机铝、矿物纤维、表面活性剂、硅酸钠、水为原料并进行适当配比，制备时，在加热条件下，将无机铝分散于水中，再加入矿物纤维进行搅拌均匀，降温后加入表面活性剂，再进行搅拌混合，最后调节pH后，加入硅酸钠，搅拌后最终制得混凝土防水密实剂；将所述防水密实剂用于混凝土中，能显著提高抗渗性，减少混凝土收缩，防止混凝土开裂，有效阻止水分渗透，同时还能显著提高混凝土强度。
