Problems solved by technology

During the detection process, it was found that although this method can statistically analyze the size and area of ​​pores on the concrete surface, in the process of image collection, the angle of photography, the light and shade, and the color difference of the concrete surface will have a great impact on the final detection results.

Embodiment 1

[0032] A slurry for marking pores on the surface of concrete. The raw materials are composed of P.W32.5 cement, polycarboxylate water reducer, methyl cellulose ether, redispersible latex powder, distilled water, and nano-titanium dioxide. The specific addition amount 61% of P·W32.5 cement, 0.5% of water reducer, 0.5% of methyl cellulose ether, 5% of redispersible latex powder, 25% of distilled water, and 8% of nano titanium dioxide. The above-mentioned raw materials were uniformly mixed according to the stated ratio, and then stirred rapidly in a mixer for 2 minutes to prepare a slurry.

[0033] The method that described slurry is used for concrete surface pore detection is as follows:

[0034] S1. Use a soft brush to sweep away the debris on the concrete surface, rinse it under flowing water for 1 minute, and then use a wet towel to remove the clear water on the concrete surface;

[0035] S2. Take the slurry, apply it evenly on the concrete surface with a scraper, keep the s...

Abstract

The invention provides a preparation method of slurry for marking pores on the surface of concrete and a pore detection method. The detection method comprises the following steps: preparing a coating, washing the surface of concrete, removing water, coating the surface of the concrete with the coating, wiping off redundant slurry in pores in the surface of the concrete after the coating is dried, and acquiring and analyzing a concrete surface image. The color of the used slurry is obviously different from the inherent color of the concrete, so that the interference of photographing angle, light and concrete surface color difference on pore detection during image collection is effectively eliminated, the position, the size and the pore area of the pore can be more accurately marked, and the test result is more accurate and reliable.

Description

technical field [0001] The invention relates to the field of concrete material technology and detection technology, in particular to a method for preparing slurry for marking pores on the concrete surface and for detecting pores. Background technique [0002] With the continuous development of concrete technology and the continuous upgrading of the construction industry, the apparent quality of concrete has begun to attract attention. First of all, the excellent apparent quality of concrete generally does not require secondary treatment after concrete pouring, so it can save a lot of material costs and labor costs; secondly, the excellent apparent quality of concrete can improve the durability of concrete; finally, excellent The apparent quality of concrete gives concrete an austere aesthetic that other materials don't have. Surface pores are the main factors affecting the apparent quality of concrete, and the detection of surface pores has become the main content of testin...
