Geopolymer water-permeable concrete brick containing biomass charcoal

The geopolymer permeable concrete brick comprises the following raw materials: 250-350kg/m < 3 > of geopolymer cementing material, 1200-1500kg/m < 3 > of fine aggregate (containing primary aggregate and recycled aggregate, the volume ratio of the recycled aggregate is 35%-100%), and 300-500kg/m < 3 > of recycled coarse aggregate, and the main mixing ratio design parameter value ranges are as follows: the water-binder ratio is 0.24-0.42, the slurry-to-bone ratio is 1: 3.8-1: 4.7, the water-to-bone ratio is 1: 3.8-1: 4.7, and the water-to-bone ratio is 1: 1. The maximum nominal particle size of the fine aggregate is 1-5 mm, the maximum nominal particle size of the coarse aggregate is 5-10 mm, and the recycled aggregate completely has physical and mechanical properties required by pavement, is high in strength, good in wear resistance, appropriate in friction coefficient and good in durability, has multiple functions of water permeability, air permeability, permeation, sound absorption, heat preservation, moistu
