Abstract

The invention discloses coal gasification slag all-component pervious concrete. Ground coal gasification slag is taken as a silicon-aluminum raw material to prepare a coal gasification slag geopolymerwith good mechanical properties as a cementing material; and screened coal gasification slag is used as aggregate to prepare the pervious concrete which have adaptive mechanical properties and waterpermeability and has good wear resistance and water purification performance. The aggregate and the silicon-aluminum raw material used in the invention are both the coal gasification slag, so that theindustrial solid waste coal gasification slag is fully utilized, and the purpose of resource utilization is achieved. Meanwhile, the coal gasification slag contains a certain amount of activated carbon, so that the adsorption performance of the pervious concrete can be improved, and the pervious concrete which has adaptive mechanical properties and water permeability and has good wear resistanceand water purification performance is obtained.

Description

technical field

[0001] The invention belongs to the technical field of materials, and in particular relates to a permeable concrete with full components of coal gasification slag. Background technique

[0002] Coal gasification slag is the solid waste produced in the process of coal gasification. Since coal is the most important energy source in our country and the coal gasification process is one of the important technologies in the coal industry, a large amount of coal gasification slag is discharged every year in our country, and the large amount of coal gasification slag is seriously harmful to the environment. Therefore, the coal gasification slag The utilization of resources is an urgent problem to be solved.

[0003] At present, the country has put forward the requirement of building a "sponge city", through the application of a large number of permeable materials, to realize the natural accumulation, natural infiltration and natural purification of rainwater in the ...
