Problems solved by technology

[0006] In order to solve the problem of efflorescence in concrete, some researchers add anti-efflorescence agents to concrete raw materials, but this will not only increase the production cost, but also affect the performance of concrete due to the change of raw material components

preparation example Construction

[0015] Preparation method of transfer concrete:

[0016] Print the retarder on the base film according to the set pattern, pour concrete on the base film, uncover the base film after the concrete hardens, and wash the concrete surface with water to obtain the transferred concrete with the corresponding pattern.

[0017] Methods to prevent efflorescence on the surface of transferred concrete:

[0018] Include the following steps:

[0019] a. Vacuum drying: Put the freshly washed transfer concrete into a vacuum drying oven for vacuum drying;

[0020] b. Carbonation: Carry out surface accelerated carbonation treatment to the dry transfer concrete, and the surface accelerated carbonation condition is: CO 2 Concentration not less than 99%, CO 2 The pressure is not less than 0.2MPa; the carbonization time is 2-4h.

[0021] The parameters and effects of Examples 1-5 using the above method are shown in Table 1, and the parameters and effects of Comparative Examples 6-10 are shown ...

Abstract

The invention discloses a method for rapidly treating the surface of transfer printing concrete. The method solves the problem that the color difference is caused due to the fact that the surface of existing transfer printing concrete is prone to whiskering. According to the technical scheme, the method comprises the following steps: putting the just-scoured transfer printing concrete into a vacuum drying oven for vacuum drying; and then carrying out surface accelerated carbonation treatment on the dried transfer printing concrete. The method has a remarkable anti-whiskering effect, is stableand reliable, and is capable of effectively improving the yield and impression quality of the transfer printing concrete.

Description

technical field [0001] The invention relates to the field of concrete decoration, in particular to a method for preventing efflorescence on the surface of transferred concrete. Background technique [0002] Transfer concrete is a kind of decorative concrete that exposes the aggregate of the patterned part of the concrete surface through retarding technology to form a pattern. Compared with ordinary decorative materials, transfer-printed concrete patterns are fine and complex, and can be changed at will, which can give architectural designers great creative space and achieve excellent artistic effects. Therefore, the development of transfer concrete is getting faster and faster, and the scope of application is getting wider and wider. [0003] The commonly used production method of transfer printing concrete is to print the retarder on the base film according to the set pattern, pour concrete on the base film, uncover the base film after the concrete hardens, and wash the co...
