Example Embodiment

[0020] The present invention will be further described below in conjunction with specific embodiments:

[0021] As an example, the manufacturing method of the artificial reef in this embodiment includes the following steps:

[0022] Step 1. The cement is 86% (wt) of ordinary Portland cement with the label of 42.5R, the admixture is 14% (wt) of fly ash, and the ratio of water to material is 0.43. The additives include water reducer and foam stabilizer. , The content of which accounts for 1.48% (wt) and 0.013% (wt) of the mass of cement cementing materials, respectively. The chemical foaming agent uses hydrogen peroxide, and its content accounts for 7% (wt) of the mass of cement cementing materials. Cement, admixtures, admixtures, and water are mixed and stirred at high speed until uniform, and the stirring time is controlled within 4min-5min; then the above chemical foaming agent is added to the slurry to continue stirring, and the stirring time is preferably controlled at about 10s...

Abstract

The invention discloses a method for making an artificial fishing reef, comprising the following steps: S1, stirring and mixing cement, an admixture, an additive and water in a specific proportion evenly, then adding a chemical foaming agent, stirring and mixing; S2, pouring a semi-finished product obtained in S1 into a mold for moulding, waiting for foaming, and then curing for a required periodafter demoulding; S3, punching the semi-finished product obtained from S2, thus obtaining the artificial fishing reef. By using the simple and feasible preparation method, the prepared finished product has a larger surface area, internal and external micro-holes and lower self-weight through the selection of raw materials, chemical foaming and punching treatment, being conducive to the habitat, reproduction and growth of fish and other marine organisms, conducive to the increase of biological density, and conducive to the efficient use of marine resources.

Description

technical field [0001] The invention relates to the field of artificial fish reefs, in particular to a method for making artificial fish reefs. Background technique [0002] Granite powder is the powder waste generated during the cutting process of granite. In the slate industry area, a large amount of granite powder waste cannot be disposed of in time, and a large amount of granite powder will occupy land due to long-term accumulation. Moreover, the granite powder is fine in texture and difficult to handle. It is easy to fly all over the ground in strong winds, and it will flow into rivers with rainwater in rainy days, which will not only pollute the environment but also cause great harm to the human body. [0003] A natural fish reef is a kind of reef formed by accumulation of fish bones or waste discharged by fish over many years. The rough surface of the reef formed by long-term accumulation in nature is suitable for the attachment of fish eggs, thereby protecting the ...
