River sediment adsorption brick and preparation method thereof
The invention provides a river sediment adsorption brick comprising following components: 40-50 parts of river sediment, 15-20 parts of cements, 10-15 parts of zeolite powder, 5-10 parts of zeolite, and 2.5-5 parts of gypsum; water accounts for 32-36% of total of solid materials, and a foaming agent accounts for 0.1-0.2% of total water amount. The invention also provides a preparation method for the river sediment adsorption brick, comprising steps: mixing the river sediment, cement, zeolite powder, and gypsum uniformly to make a mixture, adding the foaming agent in water and stirring until foams occur; adding the solution in the mixture; laying the zeolite evenly and uniformly on the bottom of a standard mold, pouring the mixed slurry in the standard mold, maintaining and demolding, and maintaining for the second time, thereby obtaining the river sediment adsorption brick. In the invention, the river sediment content amounts to 45-65%, the river sediment has a high utilization rate, and the river sediment adsorption brick has a high compressive strength which is no less than MU7.5 grade, and can substitute for the traditional solid chamotte brick.
