Problems solved by technology

[0004] However, the above-mentioned method has the following problems. The cement filling in the V-shaped groove only forms a repair on the surface of the bridge cracks. However, the cracks inside the bridge structure are still not repaired, and the cracks inside the bridge continue to develop in the later stage, which will still cause damage to the bridge structure

Abstract

The invention discloses a special grouting material for bridge repair, relates to the field of bridge repair, and aims at solving the problem that an existing bridge crack repairing method cannot effectively repair cracks in a bridge. The grouting material is prepared from the following raw materials in parts by weight: 55-89 parts of Portland cement, 6-10 parts of expansive cement, 6-12 parts ofbentonite, 9-15 parts of absolute ethyl alcohol, 10-18 parts of isopropanol, 12-20 parts of nano silica sol, 9-15 parts of magnesium aluminum silicate, 18-26 parts of filler, 5-9 parts of penetrant, 4-7 parts of leveling agent, 5-9 parts of anti-aging agent and 100-150 parts of water. By means of the self-permeation performance of the grouting material, the grouting material fully permeates into cracks in the bridge, the cracks in the bridge are fully filled, the overall bonding force of the bridge structure is improved, and the overall repairing quality of the bridge cracks is greatly improved; and the grouting material has excellent strength after being cured, and can be used for plugging exposed reinforcing steel bars of the bridge.

Description

technical field [0001] The invention relates to the field of bridge repair, more specifically, it relates to a special grouting material for bridge repair. Background technique [0002] Reinforced concrete is currently the most widely used building material in the world. It is widely used in the construction of modern projects such as ports, dams, highways, bridges, and municipal projects. However, with the rapid development of the economy and the continuous advancement of science and technology, the amount of concrete is also increasing. The larger the size, the more complex the concrete structure, and the consequent damage to the concrete structure is also increasing. [0003] As a common reinforced concrete structure, the bridge will suffer from various loads for a long time, and after a period of time, the bridge will crack and other problems. The existing crack repair method is to use cement to seal the treatment. The main operation is, first Clean the surface of bridg...
