Problems solved by technology

[0002] In the process of repairing engineering projects such as houses and roads, in order to save costs and maintain the original architectural style, the old construction method is adopted for the original facilities, and the damaged or missing components need to be treated as old, but in practice During operation, after the damaged concrete components are repaired with conventional paint, their color is very different from the color of the original concrete components after many years, and the effect of "repairing the old as old" of the cultural relics cannot be achieved in terms of appearance.

Embodiment 1

[0031] Example 1. The surface of concrete products is made of old materials

[0032] A material formula for making the surface of a concrete product old and comprising: rice husk ash, wood vinegar and a color adjusting component, the pH value of the old material is 2-3, the color adjusting component is coarse wood vinegar or water, and the rice husk ash The weight ratio to the wood vinegar is 20-40:100, and the weight ratio of the color adjusting component to the wood vinegar is 0-50:100-50.

[0033] By weight, wood vinegar: crude wood vinegar (water): rice husk ash = 100-50:0-50:35 is preferred.

Embodiment 2

[0034] Embodiment 2, the old construction method of concrete product surface

[0035] The old construction method includes the following steps:

[0036] A1. Sampling repair, embed the surface of the concrete product that needs to be replicated, and repair the missing parts with external wall putty powder in layers. If the damaged parts are more serious, use the mold to restore the original, pour concrete inside, and use planting for new and old concrete. Reinforcing with tendons;

[0037] A2. Clean the surface of concrete products; clean and dry the surface of concrete products, brush mold release agent on the surface of concrete products, place them on a clean and flat operating platform and stabilize, and place the required silica gel and curing agent in the container according to the mixing ratio of the silica gel mold. Stir evenly to form a silicone mixture, and let it stand for 10 minutes. When the silicone mixture reaches the ideal flow state, apply the silicone mixture...

Abstract

The first aspect of the present invention provides a surface aged material for concrete products, the aged material includes: rice husk ash, wood vinegar, and crude wood vinegar or water is selected as the aged color adjusting component according to the needs; the present invention The second aspect provides a method for aging the surface of concrete products, the main steps include: A1, sampling and repairing; A2, cleaning the surface of concrete products; A3, aging treatment on the surface of concrete products; A4, curing of finished products. The old material and the old method provided by the invention can effectively save costs, maintain the original architectural style, and realize the construction effect of repairing the old as the old facility.

Description

technical field [0001] The invention relates to the field of building material engineering, and relates to an aged material on the surface of a concrete product and a aged construction method. Background technique [0002] In the process of repairing engineering projects such as houses and roads, in order to save costs and maintain the original architectural style, the old-fashioned construction method is adopted for the original facilities, and the damaged or missing components need to be treated as old, but in practice In operation, after the damaged concrete components are repaired by conventional coatings, the color and luster are very different from the color and luster formed by the original concrete components after many years, and the effect of “repairing the old as the old” of the cultural relics building cannot be achieved in terms of appearance and perception. [0003] Therefore, the development needs to develop a material and a method for making the surface of co...
