Problems solved by technology

At present, in order to solve these problems of wood-grain fair-faced concrete, the concrete is usually protected by brushing a protective agent on the concrete surface, but the protective layer formed by the protective agent can only temporarily protect the concrete from the erosion of the external environment. When exposed for a long time, when the protective layer itself is damaged, the wood-grained fair-faced concrete is still easily affected by the environment and its quality deteriorates

Embodiment 1

[0040] A weather-resistant wood-grain fair-faced concrete. The raw materials include the following components in parts by weight: 415 parts of cement; 25 parts of fly ash; 700 parts of sand; 1000 parts of stone; 4 parts of water reducing agent; 3 parts of defoaming agent; 10 parts of zinc powder; 160 parts of water.

[0041] The antifoaming agent comprises the following components in weight percentage: 20% of alkyldiethanolamide phosphate, 40% of simethicone oil, and 40% of sodium carboxymethylcellulose.

Embodiment 2

[0043] A kind of weather-resistant wood-grain fair-faced concrete. The raw materials include the following components in parts by weight: 415 parts of cement, 25 parts of fly ash, 700 parts of sand, 1000 parts of stone, 4 parts of water reducing agent, 3 parts of defoaming agent, 10 parts of zinc powder, 160 parts of water, 5 parts of gelled microcapsules, and 3 parts of Grubbs catalyst.

[0044] The core material of the gelled microcapsule is dicyclopentadiene, and the wall material of the gelled microcapsule is polyurea-formaldehyde resin.

[0045] The particle size of the gelled microcapsules is controlled at 10 μm.

[0046] The antifoaming agent comprises the following components in weight percentage: 20% of alkyldiethanolamide phosphate, 40% of simethicone oil, and 40% of sodium carboxymethylcellulose.

Embodiment 3

[0048]The difference with Example 2 is that the gelled microcapsules and the Grubb catalyst surface are first pretreated and then mixed into the raw materials of the wood-grain fair-faced concrete, and the pretreatment includes the following steps:

[0049] Step 1): immerse the gelled microcapsules and Grubbs catalyst in polymethyl methacrylate for 30 minutes;

[0050] Step 2): The gelled microcapsules and the Grubbs catalyst soaked in step 1) are pulled out, then the graphite powder is sprayed onto the surface of the gelled microcapsules and the Grubbs catalyst, and then the gelled microcapsules and the Grubbs catalyst are placed put into an oven, and dry at 60°C to obtain the pretreated gelled microcapsules and Grubbs catalyst.

Abstract

The invention relates to the field of concrete, and particularly discloses weather-resistant wood grain fair-faced concrete which is prepared from the following raw materials in parts by weight: 415-545 parts of cement, 25-35 parts of coal ash, 700-750 parts of sand, 1000-1100 parts of stones, 4-8 parts of a water reducing agent, 3-6 parts of a defoaming agent, 10-20 parts of zinc powder and 160-180 parts of water. The wood grain fair-faced concrete has the advantage of improving the weather resistance of the wood grain fair-faced concrete.

Description

technical field [0001] The application relates to the field of fair-faced concrete, and more specifically, it relates to a weather-resistant wood-grain fair-faced concrete. Background technique [0002] Since the development of concrete, under the influence of modern aesthetics and art, concrete has not only been used as a building structure material, but also can be used as an indoor and outdoor market material for architectural works. Wood-grain fair-faced concrete is a concrete with a wood grain on the surface that is in harmony with the surrounding environment. [0003] Wood-grain fair-faced concrete uses the easy formability of concrete, chooses reasonable wood grain as the formwork, and directly pours the shaped building. The concrete surface will show different decorative effects depending on the wood grain surface, which is the most textured expression method. [0004] Compared with ordinary concrete, wood-grain fair-faced concrete has no plastering layer and finish...
