Abstract
The invention discloses a concrete distressing method, which mainly comprises 4 steps: step 1, before concrete pouring, assembling a mould, and spraying a layer of concrete ageing treatment liquid A on the inner surface of the mould; step 2, pouring concrete into the mould, curing and demoulding; step 3, washing the surface of the demolded concrete with clear water; and 4, spraying the ageing treatment liquid B after the water on the surface of the concrete is evaporated. The method provided by the invention enables the concrete to directly achieve the antique effect after demoulding through the pretreatment, is convenient and environment-friendly, and has no great influence on the durability of the concrete.
Description
Technical Field
The invention relates to a concrete antiquing method, in particular to a factory precast concrete antiquing method.
Background
The concrete antiquing is used as a more specialized process in the transformation of the existing old urban area, and the brand-new concrete product is processed to form a ceremony which looks like decades, so that a vicious feeling and a deep feeling can be given to people, the precipitation of years is endowed, the visual impact of the concrete is consistent with that of the old urban area and ancient buildings, and the concrete is coordinated with the whole area.
The existing concrete antique-finishing technology corrodes the surface of concrete by chemical substances such as acid and the like, so that the antique-finishing effect is achieved, but the effect is not ideal, and as the concrete emulsion is hard in quality, high in density and not easy to corrode, and the traditional treatment technology is difficult to uniformly corrode the concrete emulsion, the effect is difficult to meet the requirement, and the cost is high. The economy and the environmental protection are relatively poor, and the environmental pollution is serious.
Disclosure of Invention
The invention solves the problem of providing a concrete antiquing method, which directly achieves the antiquing effect after the concrete is demolded through the early treatment, is convenient and environment-friendly, and has no great influence on the durability of the concrete.
In order to solve the above problems, the present invention provides a concrete distressing method, comprising:
step 1, before concrete pouring, assembling a mould, and spraying a layer of concrete ageing treatment liquid A on the inner surface of the mould;
step 2, pouring concrete into the mould, curing and demoulding;
step 3, washing the surface of the demolded concrete with clear water;
and 4, spraying the ageing treatment liquid B after the water on the surface of the concrete is evaporated.
In the invention, the ageing treatment liquid A is prepared from one or more of starch, casein, sucrose, glucose, calcium lignosulfonate, carboxymethyl cellulose and carboxyethyl cellulose.
In the invention, different concrete ageing degrees can be presented by adjusting the formula of the ageing treatment fluid A.
In the invention, the ageing treatment liquid B is prepared by mixing nano-scale acrylic acid and water according to a certain proportion.
According to the invention, the ageing method can treat a large amount of concrete products at one time and the ageing degree is consistent.
The invention provides a concrete distressing method, which comprises the following specific steps:
(1) mold assembly
And cleaning and assembling the die according to specific requirements.
(2) Spray coating aging treatment liquid A
According to the specific distressing effect, the proportion of the distressing treatment liquid A and the water is adjusted, and the general proportion of the distressing treatment liquid A to the water can be selected to be 1:1, 1:2, 1:3, 1:4, 1:5 and the like. And uniformly spraying the prepared ageing treatment liquid A on the contact surface of the mould and the concrete to be aged.
(3) Pouring and demoulding concrete
And pouring the fresh concrete into the mold coated with the old treatment liquid A, standing and maintaining for 24 hours, and then demolding.
(4) Surface rinsing
And (4) washing the concrete surface contacting with the ageing treatment liquid A by using clear water, washing out uncured concrete components, standing and airing.
(5) Spray coating ageing treatment liquid B
Uniformly mixing the ageing treatment liquid B and water according to the mass ratio of 1:1, and spraying the mixture on the surface of the dried concrete to enable the ageing treatment liquid B to fully permeate into pores on the surface of the concrete to form a protective layer.
Detailed Description
The following examples are merely illustrative of the technical solutions of the present invention and are not to be construed as limiting the claims of the present invention.
Example 1
Preparing 30 rigid molds of 400mm by 60mm, and cleaning and assembling the molds; blending the ageing treatment fluid A and water according to the mass ratio of 1:4, and uniformly spraying the prepared ageing treatment fluid A on a 400mm x 400mm rigid die surface; pouring the fresh concrete into the mold coated with the old treatment liquid A, standing and maintaining for 24 hours, and then demolding; washing the concrete surface of 400mm x 400mm contacting the ageing treatment liquid A with clear water, washing out uncured concrete components, standing and airing for 3 hours; uniformly mixing the ageing treatment liquid B and water according to the mass ratio of 1:1, spraying the mixture on the surface of dried concrete with the thickness of 400mm to 400mm, standing for 3 hours after spraying, and enabling the ageing treatment liquid B to fully permeate into pores on the surface of the concrete to form a protective layer, thus finishing the ageing process.
