Problems solved by technology

The disadvantage of the artificial reef prepared by this method is that it must be cured at high temperature, the process is complicated, the cost is high, and the strength is about 40MPa.
The strength levels of the two patents are also not suitable for the preparation of artificial reefs with low cost, large volume, large porosity and complex structure

Abstract

The invention relates to the technical field of slag machining, the field of marine environmental protection, and the field of fishery industry basic facilities, in particular to a preparation method for an artificial fish reef concrete material with slag as a main raw material. The preparation method for the artificial fish reef concrete material with the slag as the main raw material is characterized in that the slag which is machined through a tightly-closed method technology is respectively used in rough aggregate, fine aggregate and binding material raw materials, and mineral waste residues, cement clinker, and flue gas desulfurization gypsum are mixed into binding materials. Compared with the prior art, the preparation method has the advantages that infiltration quantity of the slag is not lower than 75% and the slag is suitable for construction of an artificial fish reef with a large volume, a large hole rate and a complex structure, the strength of the slag can reach to 54-82MPa so that construction of the artificial fish reef can be satisfied and compact of sea tide and sea waves is resisted; the difficulties that the slag is deposited in a bulk mode, land is occupied and environment is polluted are resolved; solid waste such as the mineral waste residues and the desulfurization gypsum are further applied, and the use ratio of the solid waste can reach above 97%, and the preparation method for the artificial fish reef concrete material with slag as the main raw material has obvious resource benefits, environmental benefits, economical benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of steel slag treatment, the field of marine environment protection and the field of fishery infrastructure, in particular to a preparation method of an artificial fish reef concrete material with steel slag as the main raw material. Background technique [0002] Steel slag is the main waste slag in the metallurgical industry, and its production accounts for 10%-25% of steel output. At present, the annual discharge of steel slag in my country reaches 19 million tons, and the existing accumulation exceeds 300 million tons, but the utilization rate of steel slag is at a low level. level, about 20%. With the development of the steel industry, the discharge of steel slag will continue to increase. The low utilization rate causes a large amount of steel slag to accumulate, occupies land, pollutes the environment, and reduces the economic benefits of iron and steel enterprises. It is urgent to use the existing ste...
