In the last article, we introduced what is color concrete, I believe you have a certain understanding of color concrete, have not yet understood the partners can look at the last article through this link http://cementmixs.com/newsinfo1001. Today we will continue to talk about how to make color concrete pavement.
1. After closing the traffic in the construction section, carefully clean the gravel, soil and debris in the water-stabilized layer. Before mixing, asphalt mixing equipment, transportation equipment and construction machinery should be cleaned to avoid contamination by impurities. Waterproof binder and color binder for anti-skid thin pavement should be warned. Take a large capacity mixing barrel, weigh its total weight with the mixing rod, then weigh the component A of the design quantity, and add the component B of the design quantity to mix. The process of manual mixing cementitious materials should be as consistent as possible, and should be strictly controlled according to the design of the laboratory. It is recommended that mechanical stirring cementing material be adopted to control the stirring speed, time and process accurately and ensure the quality of cementing material.
2. The waterproof bonding material can be constructed by manual brushing. The amount of brushing can be controlled evenly, and a layer of film can be formed at the original road surface and joint. The dust and slurry on the original pavement, which may reduce the strength and stability of the pavement structure, are thoroughly cleaned. The designed amount of cementing material is weighed and the reactive waterproof adhesive layer is evenly coated on the clean original pavement.
3. Put the designed amount of stone in the concrete mixer, start the machine and make it run. At the same time, weigh the designed amount of pigments and evenly add them into the mixer. After the basic mixing of pigments and stones, add the designed amount of binder. Finally, in the binder and the basic coated stone table of pigments. The process lasts about 10 to 15 minutes. At the same time, special attention should be paid to the fact that the deviation of concrete mixing process will cause the color difference of ES color pavement. Therefore, each process should be accurately controlled, such as mixing time, mixing speed, etc. Otherwise, some bad problems such as color difference will occur.
The concrete mixer produced by our company has many advantages, such as good quality, high performance, simple operation, easy maintenance and so on.
