The invention relates to the technical field of concrete slabs, and discloses a special crack sealer for autoclaved aerated concrete slabs, which comprises the following components: 25-35% of cement, 10-30% of gypsum, 30-40% of high-performance fine sand, 1-5% of fiber reinforced material, 5-10% of binder and 15-25% of fiber water, preferably, the cement is ordinary Portland cement, preferably, the binder is a water-retaining agent, preferably, the water-retaining agent is a water-retaining agent, preferably, the water-retaining agent is a water-retaining agent, preferably, the water-retaining agent is a water-retaining agent, and preferably, the water-retaining agent is a water-retaining agent. The high-performance fine sand has uniform particle size distribution, preferably, the fiber reinforced material is polypropylene fiber and has certain length and strength, preferably, the adhesive is acrylic emulsion and has high bonding strength. The ordinary Portland cement and the acrylic emulsion are adopted as adhesives, the bonding strength of the crack-sealer and a concrete plate can be improved, it is ensured that the crack-sealer is firmly bonded to the surface of the plate, the water resistance of the crack-sealer can be enhanced by adding the gypsum, water is effectively prevented from permeating into the concrete plate, and the crack-sealer is prevented from being damaged. Therefore, durability and service life of the concrete plate are improved.
本发明涉及混凝土板材技术领域，公开了一种蒸压加气混凝土板材专用勾缝剂，包括以下成份：25‑35％水泥、10‑30％石膏、30‑40％高性能细砂、1‑5％纤维增强材料、5‑10％黏结剂和15‑25％纤水，优选的，所述水泥为普通硅酸盐水泥，优选的，所述高性能细砂具有均匀的颗粒粒径分布，优选的，所述纤维增强材料为聚丙烯纤维，并具有一定的长度和强度，优选的，所述黏结剂为丙烯酸乳液，并具有较高的粘结强度。通过采用普通硅酸盐水泥和丙烯酸乳液作为黏结剂，可以提高勾缝剂与混凝土板材的粘结强度，确保勾缝剂牢固地粘结在板材表面，并且通过石膏的添加可以增强勾缝剂的耐水性，有效防止水分渗透到混凝土板材内部，从而提高混凝土板材的耐久性和使用寿命。
