Preparation method of environment-friendly pervious concrete for highway engineering

[0018] Example 1

[0019] An environmentally-friendly water-permeable concrete for highway engineering. The amount of each component of the concrete is 300 parts by weight, 1000 parts of granite gravel, 50 parts of porous silicon carbide ceramic particles, 1 part of polyvinyl acetate, and fiber reinforcement. 50 parts, 30 parts of brightener, 12 parts of coloring agent, 30 parts of water reducing agent and 600 parts of water. Among them, the grain size of granite gravel is 4mm.

[0020] The preparation method of environmentally friendly permeable concrete for highway engineering includes the following steps:

[0021] Firstly, weigh the raw materials according to the mass percentage; secondly, add the emulsion to 10-15 weight multiples of water and stir and mix to obtain an emulsification reagent; then, mix the cement, porous silicon carbide ceramic particles and fiber reinforcement uniformly to form a dry powder , Then add water to the dry powder and stir for 30-60s to obtain a mixtur
