Ecological concrete for repairing river pollution and preparation method thereof

Abstract

The invention discloses ecological concrete for repairing river pollution and a preparation method of the ecological concrete. The ecological concrete is prepared from the following components in parts by weight: 270 parts of river bottom mud, 120-230 parts of a gel material, 65-70 parts of water, 3-5 parts of a water reducing agent, 6-10 parts of a foaming agent and 2-4 parts of nano manganese dioxide. Based on a waste recycling concept, the river sediment is used for the ecological concrete, so that the mechanical property of the concrete can be guaranteed, the environmental harmfulness of the river sediment is reduced, the production cost is reduced, the nano-manganese dioxide has a good catalytic characteristic, the compressive strength of the ecological concrete can be improved, and the removal effect on heavy metals and organic matters can be improved; finally, the adsorption performance of the concrete-plant-microorganism system on pollutants is enhanced. The ecological concrete provided by the invention realizes resource sustainability, and has excellent environmental adaptability and enhanced river pollutant reduction performance.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to ecological concrete used for river pollution restoration and a preparation method thereof. Background technique [0002] In recent years, with the development of social economy and urbanization, the pollution of rivers, lakes and reservoirs in my country has become increasingly serious. How to prevent and control water pollution and the research on the restoration technology of polluted water has become the focus of water environment protection research. To find solutions to water pollution problems, on the one hand, control point source pollution and non-point source pollution; ecosystem. The former can be promoted through mandatory policies and regulations, while the latter can be realized through ecological water treatment technology and in-situ water ecological restoration projects. [0003] Ecological concrete is a kind of concrete with special structure and function, sma...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there is little use of river sediments to prepare concrete, and at the same time, the ecological benefits of concrete have not been increased, and the effect of ecological concrete to purify water quality has not been achieved.
