The invention discloses a water-permeable concrete
brick loaded with a
metal-organic framework material and a preparation method of the water-permeable concrete
brick. The method comprises the following steps: mixing a
silicon-aluminum material and an alkali activator to prepare
geopolymer slurry, adding an organic amine
reagent, mixing, and uniformly stirring to obtain modified
geopolymer slurry; aggregate is added into the modified
geopolymer slurry, the mixture is uniformly stirred and then loaded into a test mold, the test mold is demolded after standing for 1-2 days, a geopolymer water-permeable concrete
brick is obtained, a
metal salt solution is uniformly sprayed to the geopolymer water-permeable concrete brick, and the geopolymer water-permeable concrete brick is taken out after being subjected to steam curing for 3-5 h; and uniformly spraying the organic ligand solution on the cured geopolymer water-permeable concrete brick, performing steam curing for 18-22 hours, taking out the geopolymer water-permeable concrete brick after curing, and
drying the geopolymer water-permeable concrete brick in a
drying oven at 80-120 DEG C for 20-30 hours to obtain the water-permeable concrete brick loaded with the
metal-organic framework material. The
pervious concrete brick prepared by the invention has better adsorption efficiency, and can play an excellent water purification function in practical application.
