Description

Technical Field

[0001] This application relates to building materials, and in particular to a highly impermeable concrete interface reinforcement structure. Background Technology

[0002] Currently, concrete is one of the most commonly used materials in construction engineering. Its impermeability is directly related to the durability and safety of the structure. With the increasing complexity of construction projects and the diversification of environmental conditions, the requirements for the impermeability of concrete are becoming higher and higher. At present, the industry mainly improves the impermeability of concrete by adding admixtures, optimizing mix proportions, and surface coatings. However, these methods still have certain limitations in long-term use, such as the stability of admixtures, the complexity of mix proportion optimization, and the durability of surface coatings.

[0003] Admixture method: By adding mineral admixtures such as silica fume and fly ash or organic waterproofing agents, the density and impermeability of concrete are improved. The advantage is simple construction, but the disadvantage is that the long-term stability of admixtures is difficult to guarantee and may affect other properties of concrete. Mix proportion optimization method: By adjusting parameters such as water-cement ratio and aggregate gradation, the density of concrete is improved. The advantage is that no additional materials are introduced, but the disadvantage is that the optimization process is complex and has high requirements for the quality of raw materials. Surface coating method: Waterproof coatings or penetrating crystallizing materials are applied to the concrete surface to form a waterproof layer. The advantage is good immediate effect, but the disadvantage is that the coating is prone to aging and peeling, and the long-term effect is not good.

[0004] Regarding the aforementioned technologies, existing technologies generally suffer from limited improvement in impermeability, insufficient long-term stability, high construction complexity, or high costs, making it difficult to meet the engineering requirements for high impermeability. Therefore, there is an urgent need for a high-impermeability concrete interface reinforcement structure. Summary of the Invention

[0008] Preferably, the fiber mesh is tightly bonded to the concrete matrix through mechanical anchoring and chemical bonding, blocking the seepage path; the polymer mortar fills the pores on the concrete surface; and the nano-silica optimizes the microstructure of the interface zone by filling the micropores and catalyzing the cement hydration reaction, forming a dense impermeable barrier.

[0009] Preferably, the structure is constructed through the following operational steps: S1: Clean the concrete substrate surface to ensure it is free of oil, dust, and loose particles; S2: Lay the fiber mesh on the surface of the concrete substrate and fix it with a special clamp; S3: Apply polymer mortar to a thickness of 3-5mm and cover with fiber mesh cloth; S4: After the polymer mortar has initially set, spray a nano-silica mixed slurry with a thickness of 0.5-1mm; S5: Keep moist for 24 hours to prevent excessive moisture evaporation.

[0010] Preferably, the fiber mesh can be replaced with carbon fiber mesh, which enhances the strength of the interface structure through its high strength and high modulus characteristics, and can be used stably for a long time in various harsh environments due to its good corrosion resistance and durability.

[0011] Preferably, the polymer mortar can be replaced with polyurethane modified mortar; the polyurethane modified mortar has excellent adhesion, can be tightly bonded to the concrete matrix and fiber mesh to form a solid whole, and can adapt to the slight deformation of the concrete matrix.

[0012] Secondly, the high impermeability concrete interface reinforcement structure provided in this application adopts the following technical solution: It also includes other construction solutions: Option 2: Pre-embed polymer fiber mesh during concrete pouring to directly form an interface reinforcement layer, eliminating the need for subsequent steps of laying fiber mesh and applying polymer mortar; Option 3: Use vacuum adsorption technology to inject nanomaterials into the surface of the concrete matrix to further optimize the microstructure control effect.

[0013] Preferably, in Scheme 2, the polymer fiber mesh is pre-embedded in the concrete matrix during concrete pouring, forming an integral whole with the concrete matrix. Through the reinforcing effect of the polymer fiber mesh and its own structural characteristics, an interface reinforcement layer is directly formed, which plays a role in blocking the penetration path and improving the interface strength.

[0014] Preferably, in Scheme 3, the vacuum adsorption technology creates a negative pressure environment on the surface of the concrete matrix, drawing nanomaterials into the pores and microcracks of the concrete matrix surface. The nanomaterials fill these pores and microcracks, optimizing the microstructure of the interface region and further improving the impermeability and density of the interface-reinforced structure.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. This structure forms a three-layer impermeable system. The concrete matrix serves as the basic load-bearing structure. The interface reinforcement layer mainly functions to block the seepage path and improve the interface strength.

When laying the fiber mesh, ensure it is mechanically bonded to the concrete matrix. The bonding effect of anchoring and polymer mortar is closely combined. Applying polymer mortar fully fills the pores on the concrete surface. Spraying nano-silica mixed slurry allows nano-silica to fill the micropores and catalyze the cement hydration reaction. These steps ensure that the interface reinforcement layer and microstructure regulation layer can be tightly bonded to the concrete matrix to form an effective impermeable structure. Cleaning the surface ensures the bonding quality. Laying and fixing the fiber mesh and applying polymer mortar form the interface reinforcement layer, blocking the seepage path. Spraying nano-silica mixed slurry forms the microstructure regulation layer, optimizing the microstructure. The curing process ensures the full curing of each layer and improves the overall performance of the structure. 2. It also includes material replacements when suitable materials cannot be found or there are more demanding requirements. Carbon fiber mesh has higher strength and modulus, can withstand greater tensile force, and plays a stronger reinforcing role in building structures. Its good corrosion resistance and durability enable it to be used stably for a long time in various harsh environments, further improving the mechanical properties and durability of interface-reinforced structures. Polyurethane modified mortar has excellent adhesion and can be tightly bonded to the concrete matrix and fiber mesh to form a solid whole, improving the stability of the structure. At the same time, it has better flexibility, can adapt to the small deformation of the concrete matrix, reduce cracks caused by stress concentration, and extend the service life of the structure. 3. Option 2 directly forms an interface reinforcement layer by pre-embedding a polymer fiber mesh, eliminating the need for subsequent steps of laying fiber mesh and applying polymer mortar, simplifying the construction process and improving construction efficiency. Option 3 uses vacuum adsorption technology to inject nanomaterials into the concrete surface, further optimizing the microstructure control effect. This allows the nanomaterials to penetrate deeper into the concrete surface, filling finer pores and improving the density and impermeability of the interface zone. The polymer fiber mesh, through its reinforcing effect and structural characteristics, directly forms an interface reinforcement layer, blocking the penetration path and improving the interface strength.
