Description
技术领域technical field
本发明属建筑材料技术领域，具体涉及一种高性能水泥基止水堵漏材料。The invention belongs to the technical field of building materials, and in particular relates to a high-performance cement-based water-stopping and leak-stopping material.
背景技术Background technique
当前，由于设计和施工时没有充分考虑混凝土材料的抗渗性和混凝土结构的脆性开裂，许多大型混凝土建筑物、混凝土防渗墙、地下室、隧道等存在着不同程度的渗漏病害，严重影响了其使用功能。而对这些结构物修补的难度非常大。通常的做法有以下两种：At present, because the impermeability of concrete materials and the brittle cracking of concrete structures are not fully considered in the design and construction, many large concrete buildings, concrete impermeable walls, basements, tunnels, etc. have different degrees of leakage diseases, which seriously affect the its use function. The difficulty of repairing these structures is very large. There are two common approaches:
1)用掺加了减水剂、防水剂和/或微膨胀剂等的水泥砂浆进行抹面；1) Use cement mortar mixed with water reducing agent, waterproofing agent and/or micro-expansion agent to plaster the surface;
2)在墙面上涂刷聚氨脂防水涂料、硅橡胶防水涂料或有机硅等。2) Brush polyurethane waterproof paint, silicone rubber waterproof paint or silicone on the wall.
这两种方法可以在一定程度上提高混凝土结构体的抗渗漏性，但是，渗漏现象往往发生在已交付和投入使用的工程中，这时由于水压力较大，用第一种方法，由于普通水泥砂浆与基层的粘结性较差且凝结时间较长，常常在其凝结硬化建立强度之前就被压力水冲垮；若采用后一种方法，一方面这些防水涂料都是溶剂型的，无法与湿墙面结合，另一方面，这样薄的涂层难以抵抗压力水的作用。所以这两种通常作法都不能有效解决已发生渗漏的混凝土结构的止水堵漏问题。These two methods can improve the leakage resistance of concrete structures to a certain extent. However, leakage often occurs in projects that have been delivered and put into use. At this time, due to the high water pressure, the first method, Because ordinary cement mortar has poor adhesion to the base and has a long setting time, it is often washed away by pressure water before it sets and hardens to build strength; if the latter method is used, on the one hand, these waterproof coatings are solvent-based, It cannot be combined with wet walls. On the other hand, such a thin coating is difficult to resist the action of pressurized water. So these two kinds of common practices all can't effectively solve the water-stopping and leak-stopping problem of the concrete structure that seepage has taken place.
发明内容Contents of the invention
本发明的目的在于提供一种能有效对混凝土建筑物(构筑物)渗水通道进行快速封堵的高性能水泥基止水堵漏材料。The object of the present invention is to provide a high-performance cement-based water-stopping and leak-stopping material that can effectively quickly block the seepage channels of concrete buildings (structures).

本发明中，减水剂为萘磺酸甲醛缩合物高效减水剂，氨基磺酸盐高效减水剂，三聚氰胺高效减水剂，聚羧酸盐高效减水剂之一种。In the present invention, the water reducer is one of naphthalenesulfonic acid formaldehyde condensate superplasticizer, sulfamate superplasticizer, melamine superplasticizer and polycarboxylate superplasticizer.
本发明的制备方法是：按前述各重量比例称量各组份，将以上原料通过物理机械混合，搅拌，即得到本产品。The preparation method of the present invention is as follows: weighing each component according to the aforementioned weight ratios, mixing and stirring the above raw materials through physical machinery to obtain the product.
本发明中，普通硅酸盐水泥作为无机胶凝材料，能与拌合水发生水化反应，产生水化产物，硬化后产生强度，并能与基底部分粘接起来，形成整体。高铝水泥的作用遇水后水化硬化速度快，使本产品具有理想的快速凝结硬化性能，利于对渗漏水处填堵后立即建立强度。0.16-2.5mm石英砂的作用是充当硬化水泥浆体的骨架，可增加强度和降低收缩。纤维素有助于改善本产品与堵漏处基底之间的粘结强度；减水剂的作用在于对砂浆起到的塑化减水作用，从而增加强度。石膏的作用在于为浆体体系提供一定量的SO4 2-，与高铝水泥的水化产物发生反应，形成具有一定体积膨胀的钙矾石，补偿砂浆的体积收缩。生石灰的作用在于仅早水化，不仅放出一定热量，加速硅酸盐水泥合高铝水泥的水化，而且为高铝水泥参与钙矾石的形成体供高浓度的碱环境。In the present invention, the ordinary Portland cement, as the inorganic gelling material, can undergo hydration reaction with mixing water to produce hydration products, which will develop strength after hardening, and can be bonded with the base part to form a whole. The high alumina cement has a fast hydration and hardening speed when it meets water, which makes this product have an ideal fast setting and hardening performance, which is conducive to building strength immediately after filling the leaking water. The role of 0.16-2.5mm quartz sand is to act as the skeleton of hardened cement paste, which can increase strength and reduce shrinkage. Cellulose helps to improve the bonding strength between this product and the base of the plugging place; the function of the water reducer is to plasticize and reduce water on the mortar, thereby increasing the strength. The role of gypsum is to provide a certain amount of SO 4 2- for the slurry system, react with the hydration products of high alumina cement, form ettringite with a certain volume expansion, and compensate for the volume shrinkage of the mortar. The role of quicklime is to hydrate early, not only to release a certain amount of heat, to accelerate the hydration of Portland cement and high-alumina cement, but also to provide a high-concentration alkaline environment for high-alumina cement to participate in the formation of ettringite.
本发明为灰色干粉状物质，使用时，适宜的加水量为干粉状材料重量的10％-25％，具体加水量根据使浆体达到的所需流动性通过试验确定。The present invention is a gray dry powder substance. When in use, the suitable amount of water added is 10%-25% of the weight of the dry powder material, and the specific amount of water added is determined through experiments according to the required fluidity of the slurry.
本发明作为止水堵漏材料使用，可有效封堵渗漏水通道，具有凝结时间快、与基层粘结强度高、收缩率低，产品特别适合于湿基底上施工等独到的特性。The invention is used as a water-stopping and leak-stopping material, which can effectively block the leakage water channel, and has unique characteristics such as fast setting time, high bonding strength with the base layer, and low shrinkage rate, and the product is especially suitable for construction on wet bases.
本发明与湿基底的粘结力大，凝结时间极短，凝结后抗压抗折强度高，且具有非常理想的补偿收缩性。The present invention has high bonding force with wet base, extremely short setting time, high compressive and flexural strength after setting, and very ideal compensating shrinkage.
本发明对混凝土内部钢筋无锈蚀作用，可广泛应用于混凝土建筑物、桥梁、隧道、地下室、大坝、水池、水塔等构筑物的止水堵漏。The invention has no corrosion effect on the steel bars inside the concrete, and can be widely used in water and leakage plugging of structures such as concrete buildings, bridges, tunnels, basements, dams, pools, water towers and the like.
