Technical field

The present invention relates to solid waste environmental protection and artificial marine habitat preparation technical field, a kind of ecological artificial marine habitat and its manufacture are provided Method, in particular to a kind of energy-saving and environment-friendly durable ecological type artificial fish shelter and its system based on magnesium phosphate cement concrete material Preparation Method.

Background technique

Portland cement concrete manufacture of intraocular fish shelter is mostly used greatly at present, on the one hand as resource is increasingly deficient, industry is secondary Product is largely stored up and Global climate change, and energy consumption is high for ordinary cement, has been not suitable with the hair of green low-carbon circular economy instantly Exhibition；On the other hand, portland cement concrete artificial marine habitat basicity is strong, and pH value is generally greater than 13.0, and the basicity of seawater generally exists 8.3 or so, portland cement concrete artificial marine habitat easily influences the stability of marine environment, with the compatibilities of marine organisms compared with Difference, in addition the chloride ion in marine environment and sulfate ion are huge to the erosion damage of portland cement concrete, it is difficult to guarantee The stability and durability of artificial marine habitat structure, this is all that it hides some dangers in being used for a long time for aquafarm.

Summary of the invention

The object of the present invention is to provide a kind of manufacturing methods of durable ecological type artificial fish shelter, especially a kind of to be based on phosphoric acid The durable ecological type artificial fish shelter preparation method of magnesium cement concrete, can not only efficiently use flyash solid waste, show The dosage for reducing ordinary cement is write, artificial marine habitat can also be extended in the service life of marine environment, guarantee its structural strength, and And the artificial marine habitat basicity is generally 8.5-11, substantially less than ordinary portland cement, can be the growth of marine organisms and attached Provide good ecological environment, while the material can effectively solidify the harmful heavy metal ions in raw material, raw to ocean State is environmentally friendly.

In order to achieve the above object, The technical solution adopted by the invention is as follows:

A kind of durable ecological type artificial fish shelter based on magnesium phosphate cement concrete, the durable ecological type artificial fish shelter Raw material component and its content it is as follows: 1m³In cement mortar contain 200~500 parts of magnesium phosphate cement, SILICA FUME 30~ It is 100 parts, 20~250 parts of flyash, 400~950 parts of fine aggregate, 700~1300 parts of coarse aggregate, 120~400 parts of mixing water, high 5~20 parts of waterproofing agent of effect.The durable ecological type artificial fish shelter basicity is 8.5-11, and compression strength 20-70MPa, anti-folding is by force 2-7Mpa, artificial marine habitat corrosion resistance of chloride ion and sulfate resistance ion erosion better performances are spent, it can be extended in marine environment In service life and guarantee its structural stability.

Further, the SILICA FUME is not H system silicon powder, and silicone content is generally 80~92%, and average grain diameter is 0.1 ~0.3 μm.

Further, the fine aggregate is middle sand, and fineness modulus is 2.3~3.0.

Further, the coarse aggregate size is 5~35mm.

Further, the high-effect water-proof agent is silica solution.

A kind of preparation method of the durable ecological type artificial fish shelter based on magnesium phosphate cement concrete, comprising the following steps:

(1) under room temperature, a certain proportion of magnesium phosphate cement, SILICA FUME, flyash and fine aggregate are uniformly mixed；

(2) under room temperature, corresponding mixing water and silica solution is added, stirs 3-6min, until slurry stirs evenly；

(3) under room temperature, coarse aggregate is added and continues to stir 2-5min, the concrete mortar stirred evenly is injected into artificial marine habitat Mold, maintenance 1-3d is stood under room temperature, and durable ecological type artificial fish shelter green body is made in demoulding.

Compared with prior art, the invention has the benefit that by magnesium phosphate cement and ordinary portland cement original washing powder coal Ash is used in combination, and manufactures artificial marine habitat, and the recycling that flyash not only may be implemented recycles, and guarantees that the artificial marine habitat has Standby excellent mechanical property, the heavy metal ion in effective curing materials, significantly improves its stable structure in marine environment Property and durability, can also greatly improve biology artificial marine habitat surface compatibility and adhesion, artificial marine habitat system is effectively reduced This is caused, there is significant innovative significance and engineering practical value, market prospects are boundless.
