The design and construction of all infrastructures in urbanization have the requirements on materials that the materials are compact and waterproof, so that natural ground surfaces are hardened by waterproof materials such as asphalt, bricks and cement, vegetation coverage rate is continuously reduced, water permeability and water storage capacity of soil are lost, and pressure of urban drainage pipelines is increased. In addition, the impermeable material is difficult to exchange heat with the atmosphere, and the surface temperature and humidity cannot be adjusted according to the environment, so that the urban heat island effect is aggravated. In order to overcome and improve such problems, scholars and specialists have studied pervious concrete, which is a lightweight porous material and has lower strength than general concrete, so that it is mainly used for construction facilities such as squares, gymnasiums, shoulders, revetments, etc. which have not very high strength requirements at present, and cannot be widely used for main road surfaces. Therefore, the problem of improving the strength of pervious concrete is urgent.
In addition, pervious concrete generally has the problem of single color, so that the pervious concrete is not attractive enough in use and can not play a role in marking through different colors. Even if a small amount of color concrete is used in the related technology, the color durability is not enough, and the color is easy to fade after long-term use, so that the practical application of the color concrete is affected.
Therefore, how to prepare a color pervious concrete with both strength and color durability is a technical problem to be solved at present.
