[0003] In recent years, due to the needs of construction, concrete is required to simulate the texture of rammed earth, simulate natural materials and textures, so that people can easily realize the ideal of harmonious coexistence and integration of buildings, humanistic environment and natural environment. The color and molding quality of the exposed concrete are the key to determining the beauty and overall appearance of the building.
[0004] Therefore, a construction method for a loess-colored imitation rammed earth texture decorative plain concrete and a wall thereof is needed. Summary of the invention
[0005] The technical problem to be solved by the present invention is to provide a loess-colored imitation rammed earth texture decorative plain concrete in view of the deficiencies of the above-mentioned prior art. The concrete controls the components to ensure stable concrete performance, which is convenient for subsequent formation of loess color and rammed earth texture. By controlling the specific components and dosage of the dye, the dye is stably combined with the concrete, and the covering power and tinting power are strong, so that the concrete has loess color, thus having the color tone of the Loess Plateau. The final molding effect is dark yellow-brown, and has the best loess color simulation effect.
[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a loess-colored imitation rammed earth texture decorative plain concrete, characterized in that the concrete is composed of the following components by mass: 340-370 parts of cement, 90-110 parts of fine sand, 785-800 parts of machine-made sand, 910-930 parts of crushed stone, 55-65 parts of fly ash, 7.4-7.8 parts of water reducer, 5-7 parts of dye, and 150-165 parts of water; the dye is composed of iron oxide yellow, iron oxide black and iron oxide red in a mass ratio of 3-5:1:1. In the present invention, by controlling the composition of concrete, the performance of concrete is guaranteed to be stable, which is convenient for the subsequent formation of loess color and rammed earth texture. By controlling the specific composition and amount of the dye, the dye is stably combined with the concrete, and the covering power and tinting power are strong, so that the concrete has loess color, thus having the tone of the color of the Loess Plateau, and the final molding effect is dark yellow-brown, with the best loess color simulation effect.
[0007] The above-mentioned loess-colored imitation rammed earth texture decorative plain concrete is characterized in that the concrete is composed of the following components in parts by mass: 345-360 parts of cement, 95-105 parts of fine sand, 790-797 parts of machine-made sand, 915-925 parts of crushed stone, 58-62 parts of fly ash, 7.5-7.7 parts of water reducer, 6-7 parts of colorant, and 155-163 parts of water; the colorant is composed of iron oxide yellow, iron oxide black and iron oxide red in a mass ratio of 4-5:1:1.
[0008] The above-mentioned loess-colored imitation rammed earth texture decorative plain concrete is characterized in that the concrete is composed of the following components by mass: 350 parts of cement, 100 parts of fine sand, 793 parts of machine-made sand, 923 parts of crushed stone, 60 parts of fly ash, 7.6 parts of water reducer, 6 parts of dye, and 160 parts of water; the dye is composed of yellow iron oxide, black iron oxide, and red iron oxide in a mass ratio of 4:1:1. The present invention optimizes the proportion of concrete so that the concrete has the best imitation loess color under the condition of having the best performance, thereby having the best loess color and imitation rammed earth texture effect.

The present invention ensures that the concrete has the best performance by controlling the specific parameters of cement, fine sand, machine-made sand, crushed stone, fly ash and water reducer.
[0010] It should be noted that the specific surface area of silicate cement is not higher than 370m 2 / kg, the mortar strength after 28 days is 48MPa~56MPa.
[0011] It should be noted that the stone content in fine sand and machine-made sand is less than 10%, and there must be no weathered particles. The mud content in fine sand is less than 2%, and the mud block content is less than 0.5%.
[0012] It should be noted that the crushed stone adopts continuous grading and impact crushing technology, with a void ratio of less than 43% and a bulk density of more than 1480kg / m 3 , the apparent density is 2650kg / m 3 ~2850kg / m 3 Pebbles cannot be used, the water absorption rate is less than 1.5%, the mud content is 0, the powder content is less than 5%, and the stone powder cannot adhere to the surface of the stone, the needle-like content is less than 5%, and the crushing value is less than 10%.
[0013] It should be noted that since fly ash has a small fineness modulus in cementitious materials, it is easy to affect the color of concrete. Therefore, the dosage of fly ash should be reduced to ensure the color homogeneity of plain concrete.
[0014] It should be noted that the water reduction rate of carboxylic acid-based high-performance water-reducing agent is not less than 25%, the slump loss in 1h is less than 2cm, it has low air content, slow setting, plasticity retention and other composite functions, and has good adaptability to cement and other raw materials.
[0015] In addition, the present invention also provides a construction method for decorating a bare concrete wall with a loess-colored imitation rammed earth texture, characterized in that the method comprises the following steps:
[0016] Step 1: Degreasing and drying the paulownia wood board, sanding and coating the surface with UV paint in sequence to obtain a paulownia wood grain solid wood template;
[0017] Step 2: Install the Paulownia wood grain solid wood template obtained in step 1 on the lining board to obtain a customized template;
[0018] Step 3: Assemble the customized template obtained in step 2 to obtain a mold;
[0019] Step 4: pouring loess-colored imitation rammed earth texture decorative fair-faced concrete into the mold obtained in step 3 to obtain a loess-colored imitation rammed earth texture decorative fair-faced concrete wall.
[0020] The present invention removes moisture and lipids in the paulownia wood board by degreasing and drying, so as to prevent the paulownia wood board from warping and cracking and affecting the concrete; the paulownia wood board is made to have no obvious wood grain texture by frosting, so as to be close to the required rammed earth texture effect; the paulownia wood grain solid wood formwork is prevented from absorbing the glossiness of the concrete surface by surface UV paint coating, so that the concrete surface is very rough, so as to prevent the deficiency of the sensory effect of the clear water concrete from being unable to be achieved; the surface of the clear water concrete wall obtained by the mold prepared by the paulownia wood grain solid wood formwork after pouring the concrete is ensured to present the effect of imitating rammed earth texture, and express the fault effect of imitating rammed earth deposition in different ages; the wall texture shows the fault profile after the imitating rammed earth layer deposition in different ages in archaeological excavation is similar, and the appearance is slightly rough; the paulownia wood grain solid wood formwork is installed on the lining board, so as to reduce the cost under the premise of ensuring the structural strength of the customized formwork, so that the customized formwork can support the concrete poured in the middle after forming the mold.
[0021] It should be noted that protective measures must be taken at all times when assembling customized formwork, and timely cover and protect in rainy, snowy and frosty weather to prevent the paulownia grain solid wood formwork from warping and deforming due to exposure to water. When installing the paulownia grain solid wood formwork, construction workers must all wear shoe covers to prevent contamination of the paulownia grain solid wood formwork.
[0022] The above method is characterized in that the height, thickness and length of the paulownia wood formwork in step 1 are 80 mm to 120 mm, 10 mm and 4 m respectively, and the thickness of the lining board is 12 mm. The present invention simulates the disorderly natural soil layers of different thicknesses by controlling the height of the paulownia wood formwork to form an irregular rammed earth texture, and performs an abstract simulation of the natural soil layer. The texture of each paulownia wood formwork will also be different, so that the simulation effect of the finally prepared loess-colored imitation rammed earth texture decorative plain concrete wall is more realistic.
[0023] The above method is characterized in that the paulownia wood grain solid wood templates of different heights on the customized template described in step 2 need to have consistent board seams at the same horizontal height, and the seams at the yin and yang corners are interlaced and not staggered, and are randomly disrupted in the vertical direction and do not form an I-shaped seam pattern. The reason why the board seams at the same horizontal height in the present invention need to be consistent is that the rammed earth is filled up layer by layer, and the height of each layer is consistent. Therefore, the board seams at the same height need to be consistent in level and also need to be interlaced at the yang corner position. The advantage of this method is that it simulates the rammed earth effect more realistically and the customized template installation is more convenient and quick. It is randomly disrupted in the vertical direction and does not form an I-shaped seam pattern to express an irregular effect. The role of irregularity is to express the irregularity of rammed earth, so that the simulation effect of the final prepared loess-colored imitation rammed earth texture decorative plain concrete wall is more realistic.
[0024] The above method is characterized in that the joints of the paulownia grain solid wood template in the customized template in step 2 are sealed with glass glue. The present invention ensures that the joints on the loess-colored imitation rammed earth texture decorative plain concrete wall are tight and the overall aesthetics of the loess-colored imitation rammed earth texture decorative plain concrete wall is ensured by sealing the joints of the paulownia grain solid wood template with glass glue.
[0025] The above method is characterized in that the paulownia grain solid wood template and the lining board in the customized template described in step 2 are stapled by slat nails, and the nailing spacing of the slat nails is 200mm-300mm, and the distance from the edge of the paulownia grain solid wood template is 20mm-30mm. The present invention ensures the connection effect of the paulownia grain solid wood template and the lining board by slat nailing and controlling the parameters of the slat nailing, ensures that the paulownia grain solid wood template does not dislocate during subsequent construction, and ensures the overall aesthetics of the loess-colored imitation rammed earth texture decorative plain concrete wall.
[0026] Compared with the prior art, the present invention has the following advantages:
[0027] 1. The concrete controls its ingredients to ensure stable performance, which facilitates the subsequent formation of loess color and rammed earth texture. By controlling the specific ingredients and dosage of the dye, the dye and concrete are stably combined, and the covering and tinting power are strong, so that the concrete has loess color and thus has the color tone of the Loess Plateau. The final molding effect is dark yellow-brown, with the best loess color simulation effect.
[0028] 2. The present invention removes moisture and lipids in the paulownia wood board by degreasing and drying to prevent the paulownia wood board from warping and cracking and affecting the concrete. The paulownia wood board is made to have no obvious wood grain texture by frosting, which is close to the required rammed earth texture effect. The surface UV paint coating is used to prevent the paulownia wood grain solid wood formwork from absorbing the glossiness of the concrete surface, making the concrete surface very rough, preventing the insufficiency of the sensory effect of clear water concrete from being achieved. It is ensured that the surface of the clear water concrete wall obtained by the mold prepared by the paulownia wood grain solid wood formwork after pouring concrete presents the effect of imitating rammed earth texture, expressing the fault effect of imitating rammed earth deposition in different ages. The wall texture shows a fault profile similar to that after the imitating rammed earth layer deposition in different ages in archaeological excavations, and the appearance is slightly rough.
[0029] 3. The present invention reduces the cost while ensuring the structural strength of the customized formwork by installing the Paulownia wood grain solid wood formwork on the lining board, so that the customized formwork can support the concrete poured in the middle after forming the mold.
[0030] 4. The reason why the plate joints at the same horizontal height in the present invention need to be consistent is that the rammed earth is filled up layer by layer, and the height of each layer is consistent. Therefore, the plate joints at the same height need to be consistent in level and also need to be intersected at the positive corners. The advantage of this method is that it simulates the rammed earth effect more realistically and the customized template installation is more convenient and quick. The random vertical disruption and the lack of I-shaped joint pattern are to express an irregular effect. The role of the irregularity is to express the irregularity of the rammed earth, so that the simulation effect of the final prepared loess-colored imitation rammed earth texture decorative plain concrete wall is more realistic.
