Embodiment 1

[0016] After cleaning, drying and crushing the oyster shells to 0.5-0.8 cm, mix cement: sand: gravel: mixing water: oyster shell powder: powder ash: mineral powder according to the mass ratio 1: 1.91: 2.89: 0.42: 0.10: 0.17 : 0.08 mixed into the concrete mixer, after mixing, put it on the vibrating table to vibrate and compact evenly, and remove the formwork after 24 hours; after the formwork removal, the concrete artificial fish reef will undergo standard maintenance for 28 days.

Embodiment 2

[0018] Wash the oyster shells, dry them in a desiccator, and crush them to 0.5-0.8 cm. Mix cement: sand: gravel: mixing water: oyster shells: powder ash: mineral powder in a mass ratio of 1: 2.18: 3.31: 0.48: 0.12 : 0.21: 0.21 mixed into the concrete mixer, after mixing, put it on the vibrating table to vibrate and compact evenly, remove the formwork after 24 hours; after the formwork removal, the concrete artificial reef will be maintained for 28 days.

Embodiment 3

[0020] Wash the oyster shells, dry them in a desiccator, and crush them to 0.5-0.8 cm, mix cement: sand: gravel: mixing water: oyster shells: powder ash: mineral powder according to the mass ratio 1: 2.55: 3.86: 0.55: 0.13 : 0.22: 0.44 mixed into the concrete mixer, after mixing, put it on the vibrating table to vibrate and compact evenly, and remove the formwork after 24 hours; after the formwork removal, the concrete artificial reef will be maintained for 28 days.

Abstract

The invention relates to a novel concrete artificial fish reef which is prepared from the following raw materials in proportion: cement, sand, stones, mixing water, oyster shell powder, fly ash and mineral powder, wherein the weight ratio of the raw materials is 1:(1.9-2.6):(2.8-3.9):(0.4-0.6):(0.1-0.2):(0.1-0.3):(0.1-0.5). A preparation method of the novel concrete artificial fish reef comprises the following steps of adding the raw materials to a concrete mixer, stirring, then placing on a vibrating table for vibrating uniform compaction, and splitting a mould after 12-34 hours; and after the mould is split, carrying out standard maintenance for 28 days. The novel concrete artificial fish reef disclosed by the invention can not dissolve out a harmful substance in a using process or influence the biological adhesion, has no pollution on the environment, is more suitable for an ocean environment on property and can be improved in artificial fish reef effect.

Description

technical field [0001] The invention relates to the utilization of waste materials in marine fishery, in particular to a novel concrete artificial fish reef and a preparation method thereof, belonging to the field of environmental protection and the technical field of fishery infrastructure. Background technique [0002] The construction of artificial reefs is a complicated submarine project, often requiring huge investment. At present, concrete artificial reefs are widely used in coastal areas at home and abroad. But concrete is not a once-and-for-all durable material. The shortcomings and limitations in actual engineering are mainly manifested in several aspects: (1) Deterioration phenomena such as cracking and edge collapse of concrete will seriously threaten the durability of concrete structures, resulting in the actual engineering The service life is shorter than the designed service life; (2) Concrete artificial fish reef needs to consume a lot of cement, sand, stone, ...
