今天由上海壓印地坪的小編給大家分享一下壓印混凝土的施工工藝！希望通過小編的分享能對您有所幫助。
壓印混凝土：
在未硬化的現澆混凝土基層上，通過著色、硬化、壓印、脫模、養護、密封保護等多道工藝制成的較具藝術韻味的地坪或墻面。適用于室內、外地坪裝飾，也可用于建筑物立面的裝飾。
物理性能：
壓印混凝土是由美國Bomanite公司創立，經過多年發展與完善，該產品在工藝的合理性、專用化學材料的穩定性與環保性以及裝飾效果方面已達成了很成熟的水平。適用范圍從室外發展到室內，從園林造景發展到娛樂、市政、商業和文化設施領域，并且以擅長承制具有較強藝術性和特殊裝飾要求的地面工程而聞名。像美國的眾多豪華酒店的室內外地坪，迪斯尼在世界各地的藝術地坪，還有主題公園如環球影視城和海洋世界的藝術地坪等等。
壓印混凝土藝術地坪技術系統因其極強的藝術性、色彩和款式方面廣泛的選擇性，低成本和綠色環保性在中國有了迅速發展。在受到領導人充分肯定的上海市城市綠地發展項目中，彩色壓印混凝土藝術地坪大面積推廣和采用，實現了很好的社會效益和市場認可度。
壓印混凝土是在攤鋪好的砼表面上，在砼表面析水消失后用干撒彩色強化劑(干粉)的方法對砼表面進行上色和強化，并使用專用工具將彩色強化劑抹入砼表層使其融為一體;待表面水分光澤消失時，即均勻施撒彩色脫膜養護劑(干粉)，并馬上用事先選定的模具在砼表面進行壓印，實現各種設計款式、紋理和色彩。待砼經過適當的清理和養護之后，在表面施涂密封劑(液體)，使藝術地坪表面防污染防滑并再次強化。完成后的壓印混凝土地坪除了具有很好的裝飾性以外，其物理性能也非常穩定。
施工工藝：
1. 鋪筑砼前按圖規定和標高支模.人行道基層砼為50mm以上,行車道基層砼為80mm以上;
2. 攤鋪標準砼.推薦配合比為:32.5水泥424KG,粗沙400KG,細沙400KG,石子(瓜子片)1100KG,水185-195KG;
3. 進行平板震動機交叉震動后用鐵輥交叉提漿.100mm以下砼使用平板震動機作業, 100mm以上砼使用插入式振搗作業;
4. 用抄平尺進行找平后進行泌水處理，在表面初凝前用手工鐵板將砼表面光平;
5. 將標準用量(4.5kg/㎡)的1/2歐進彩色硬化劑均勻播撒在初凝階段的混凝土表面;
6. 待硬化劑蔭濕后用手工鐵板或大抹刀進行一次找平收光,不要過分鏟抹混凝土表層，這樣會導致表面出水并減弱色彩;
7. 將剩下的硬化劑補撒在一次未撒勻的地方, 待蔭濕后第二次收光;
8. 在硬化劑初凝后, 表面干燥無明顯水份的情況下,播撒歐進著色脫模粉(標準用量為0.15kg/m2)后壓模. 壓模時要用力應均勻一致, 保持模具固定平整, 壓制圖案要一次成型, 不能反復壓印;
9. 待混凝土壓花地坪完全干燥凝固成型至少3-7天后,進行修邊及伸縮縫的切割, 割縫時及時用水沖洗割縫時產生的水泥漿;
10. 用水或去污劑清洗表面, 清洗擦刷表面必須要保證整個地坪清洗程度一致，否則會造成地面顏色深淺不一;
11. 沖洗的地坪表面干燥后,涂刷歐進亮光養護劑. 使壓模地坪表面防污染防滑性能再次加強. 完成后的硬化壓模地坪除了很好的裝飾性以外，其物理性能也非常穩定.
Today, by the Small series of Shanghai floor to share the construction technology of concrete imprint!Hope to share through small make up can be helpful to you.
Imprinted concrete:
In unhardened cast-in-place concrete base, through coloring, hardening, embossing, stripping, curing, sealing protection and other processes made of more artistic charm of the floor or wall.Suitable for interior, exterior floor decoration, also can be used for building facade decoration.
Physical properties:
Founded by Bomanite corporation of The United States, imprinted concrete has reached a mature level in terms of rationality of process, stability and environmental protection of special chemical materials and decorative effect after years of development and improvement.The scope of application extends from outdoor to indoor, from garden construction to entertainment, municipal, commercial and cultural facilities, and is famous for undertaking ground works with strong artistic and special decorative requirements.The indoor and outdoor floors of many luxury hotels in the United States, Disney's art floors around the world, and theme parks like Universal Studios and SeaWorld's art floors.
Embossed concrete art floor technology system because of its strong artistic quality, color and style of extensive selection, low cost and green environmental protection in China has a rapid development.In the urban green space development project of Shanghai, which has been fully recognized by the leaders, the colored imprinted concrete artistic floor has been widely promoted and adopted, which has achieved good social benefits and market recognition.
The embossed concrete is painted and strengthened on the surface of the paved concrete by means of dry sprinkling color intensifier (dry powder) after the water evaporates on the surface of the concrete. Special tools are used to rub the color intensifier into the surface of the concrete to make it into a whole.When the surface moisture gloss disappear, that is, evenly sprinkle color off the film maintenance agent (dry powder), and immediately with the mold selected in advance on the concrete surface for imprinting, to achieve a variety of design styles, textures and colors.After proper cleaning and maintenance of concrete, sealant (liquid) will be applied on the surface to prevent pollution and skid on the artistic floor surface and strengthen it again.The finished embossed concrete floor is not only very decorative, but also very stable in physical properties.
Construction technology:
1. Before concrete paving, the concrete at the pavement base shall be above 50mm and the concrete at the carriageway base shall be above 80mm;
2. Paving standard concrete. Recommended mix ratio :32.5 424KG cement, 400KG coarse sand, 400KG fine sand, 1100KG gravel (melon seed pieces), 185-195kg water;
3. After the cross vibration of the plate vibrator, cross pulping shall be carried out with iron rollers.
4. Leveling with a leveling ruler and bleeding treatment, and leveling the concrete surface with manual iron plate before the initial setting;
5. Evenly spread 1/2 of the standard dosage (4.5kg/㎡) of the euro color hardener on the surface of the concrete in the initial setting stage;
6. After the hardening agent is dampened and wet, make a leveling and finishing with a manual iron plate or a large spatula. Do not overshovel and wipe the concrete surface, which will lead to the surface water and weaken the color;
7. Apply the remaining hardener to the unevenly spread area for the first time, and wait for the second time after the shade is wet;
8. In the case that the surface is dry without obvious moisture after the initial setting of the hardener, it is necessary to spread the Eolinized demodulation powder (standard dosage is 0.15kg/m2) after pressing the die.
9. After the concrete embossed floor is completely dried and solidified for at least 3-7 days, trim the edges and cut the expansion joints, and wash the cement slurry generated during the cutting;
10. Clean the surface with water or detergent. The cleaning and brushing surface must ensure the same level of cleaning throughout the floor, or it will cause different shades of color on the floor;
11. After the surface of the washed floor is dried, it is coated with a glossy curing agent to enhance the anti-pollution and anti-skid performance of the pressed floor surface. The finished hardened and pressed floor surface is not only very decorative, but also very stable in physical properties.
