Problems solved by technology

[0003] At present, in the construction of transportation, water conservancy and other projects, the ordinary concrete used often destroys the original biological habitats of nature, thereby affecting the growth of animals, plants and microorganisms in the area, causing serious ecological environment damage.
For example, the ordinary rubble concrete slope protection usually used on both sides of the river, because the water body is enclosed in the river, cut off the material, energy and information flow of microorganisms, and destroy the distribution balance of algae in the original "symbiosis system", resulting in biological The diversity and self-purification capacity of the river are greatly reduced, the ecosystem becomes very fragile, and once pollutants flow in, it will cause serious pollution

preparation example Construction

[0051] The present invention also provides the preparation method of aforementioned ecological concrete, which comprises the following steps:

[0052] (1) pre-stirring and mixing other materials except graphene or its derivatives in the raw materials to obtain a concrete premix matrix; the amount of water used for pre-mixing is 87.5-97.5% by weight of the water amount of the mixing ratio;

[0053] (2) When the concrete premix matrix still has fluidity, add the dispersion liquid of graphene or its derivatives therein, stir and mix again, obtain concrete mixture; the dispersion liquid of described graphene or its derivatives The solvent is water; the amount of water in the dispersion is: the amount of water in the mix ratio minus the amount of water used for pre-mixing;

[0054] (3) The concrete mixture is injected into a mould, and the ecological concrete is obtained after molding and demoulding.

[0055] It should be noted that the preparation method of the dispersion liquid ...

Abstract

The embodiment of the invention provides ecological concrete and a preparation method thereof. Each cubic metre of the ecological concrete is prepared from the following raw materials in a mixing proportion:200-350kg of cement, 158-203kg of water, 1045-1533kg of coarse aggregate, 296-765kg of fine aggregate, 4.9-6.3kg of a water reducing agent, 0-135kg of ore powder and 0.1-2kg of graphene and / orderivatives thereof. According to the ecological concrete provided by the invention, the concrete and the graphene or the derivatives thereof are compounded, and attachment environment is provided formicroorganisms through the biocompatibility and favorable chemical stability of the graphene or the derivatives thereof; and when the ecological concrete is used as a slope protection material of a watercourse and a water body, or is built into an ecological island in the water body, the attachment environment is provided for the microorganisms, so that propagation of the microorganisms is facilitated, and further purification of water quality is facilitated.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to an ecological concrete and a preparation method thereof. Background technique [0002] The microorganisms in the water play the role of cleaning the sewage, and they use the organic pollutants in the water as their nutritional food. Through adsorption, absorption, oxidation, decomposition and other processes, the organic matter is turned into a simple inorganic matter, which not only meets the needs of the reproduction and life activities of microorganisms, but also purifies the sewage. The "algae-bacteria symbiosis system" refers to the nutrients such as carbon dioxide, phosphate, ammonium salt and other nutrients produced by bacteria in the pond to decompose the organic matter in the wastewater for the growth of algae. The oxygen produced by algal photosynthesis is used for the growth of bacteria, thus forming a symbiotic system. [0003] At present, in the const...
