Problems solved by technology

Although the patent is innovative in terms of low alkalinity, due to the strength limitation of the obtained reef concrete, it cannot be used to prepare artificial reefs with both large volume and large void rate and complex shape
[0007] The patent with the publication number CN101475348 describes a method for preparing artificial fish reefs with metallurgical slag as the main raw material, but the artificial fish reefs prepared by this method need to be cured at high temperature, the process is complicated, and the cost is high
Due to the limitation of strength, it is about 40MPa, and it cannot be used to prepare complex artificial reefs with large volume and large void ratio.

Embodiment 1

[0017] (1) The granite slag powder is classified with a 2.5mm square-hole screen, the coarser part on the screen is sifted out and sold as construction sand, and the lower part is dried to a moisture content of 0.4%. The dried gravel powder is classified with a 0.315mm square hole sieve, the upper part of the sieve is used as the fine aggregate of artificial reef concrete for use, and the lower part is ground in a mill to a specific surface area of ​​3000cm 2 / g.

[0018] (2) Mix the ground stone powder in step 1 with the dried water quenched blast furnace slag to a specific surface area of ​​4000 cm 2 / g, where the water-quenched blast furnace slag entering the mill has a moisture content of 0.6%. During the mixing and grinding process, the proportions of stone powder and slag on a dry basis are as follows: stone powder accounts for 60% and blast furnace water quenched slag accounts for 40%.

[0019] (3) The above-mentioned mixed fine powder of stone powder and water-quenched blas...

Abstract

The invention relates to a method for preparing a fish reef material by utilizing granite ballast powder, which belongs to the field of environmental protection and the technical field of fishery infrastructure, and aims to solve the difficulty that the granite ballast powder can not be utilized in the production process of stone materials. The invention takes ballast powder produced during the processing of natural granite as a main raw material, and prepares coarse aggregate concrete with the compressive strength of more than 70Mpa, the additive amount of ballast powder reaches 70%, and theoverall utilization rate of solid waste reaches over 80%; and the invention can be suitable for building artificial fish reels with high height, large volume, large hole ratio and complex structures.the invention utilizes the waste granite ballast powder to make the artificial fish reels, not only adds a new way to comprehensively utilize the granite ballast powder, but also solves the difficulty of the lack of raw materials in the building of artificial fish reefs, and has obvious economic and social benefits.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection and fishery infrastructure, and provides a method for preparing artificial reef materials by using waste granite gravel powder. Background technique [0002] my country has abundant granite resources, among which Quanzhou, Fujian is one of the largest stone processing and distribution centers in China, and Quanzhou alone produces 54 million square meters of stone slabs each year. 2 , Producing 540,000 m of blocks 3 . In the two items of stone slab and concrete aggregate, hundreds of thousands of tons of gravel and stone powder are discarded every year. These wastes accumulate in large quantities or are discharged to the coast, becoming a new source of pollution and seriously polluting the environment. Effective measures are urgently needed for comprehensive utilization. [0003] On the other hand, my country’s coastal areas put a large amount of cement concrete artificial reefs into the...
