Problems solved by technology

[0005] Concrete is the most commonly used material for artificial fish reef construction. It is durable, non-toxic, and has good ecological benefits. At present, concrete technology is gradually mature. With the vigorous development of the global construction industry, the demand for concrete is huge. In addition The continuous increase of transportation costs has led to an increase in the price of concrete year by year. At the same time, many environmental problems have arisen, including the incision of the river bed caused by the disorderly mining of natural sand, and the instability of the river regime endangers the safety of flood discharge; the mining of natural stone has caused local landslides, water and soil. Churn etc.
my country is a big country for shellfish farming, but the utilization rate of shellfish is very low, resulting in a large amount of discarded shells accumulating land and causing environmental problems due to aging and decomposition; there is a surplus of fly ash in concentrated coal and electricity production areas, occupying a large amount of land resources

preparation example Construction

[0029] The present application also provides a preparation method for a biogel material for marine fish reefs, comprising the following steps:

[0030] mixing fly ash, shell powder and steel slag to obtain a first mixture;

[0031] mixing the alkali activator and water to obtain a second mixture;

[0032] The first mixture and the second mixture are mixed, molded and solidified, and cured to obtain a biological gel material for marine fish reefs.

[0033] combine figure 1 , the preparation process of the biogel material used for marine fish reefs in the present application is specifically: fly ash, steel slag, and shell powder are weighed and measured by the weighing bin respectively, and then added to the mixer for stirring, and the alkali stimulant from the alkali stimulator tank and Clean water (tap water) is measured and mixed in the stirring and dissolving tank. During the dissolving and mixing process, a large amount of heat is released. After the dissolution is comple...

Embodiment 1

[0038] Fully mix 100 parts of primary fly ash, 150 parts of 10mm discarded oyster shell particles, 150 parts of 4.5mm discarded oyster shell particles and 30 parts of steel slag, and then mix Na 2 O SiO 2 20 parts, 10 parts of NaOH and 50 parts of water; then fully mix the above two mixed materials; after mixing, molding and curing are carried out, and microwave curing is carried out first. The output power of the microwave generator for microwave curing is 800-900W, and the control temperature is 40~60℃, heat for 20min at intervals of 1h, repeat 6 times, then maintain for 16h naturally, and finally pass CO 2 conservation, to obtain biogel materials for marine reefs.

Embodiment 2

[0040] Fully mix 80 parts of primary fly ash, 120 parts of 15mm discarded oyster shell particles, 120 parts of 3.5mm discarded oyster shell particles and 25 parts of steel slag, then K 2 CO 3 5 parts, 20 parts of NaOH and 45 parts of water; then fully mix the above two mixed materials; after mixing, they are molded and solidified, and then microwave curing is performed first. The output power of the microwave generator for microwave curing is 800-900W, and the control temperature is 40~60℃, heat for 20min at intervals of 1h, repeat 6 times, then maintain for 16h naturally, and finally pass CO 2 conservation, to obtain biogel materials for marine reefs.

Abstract

The invention provides a bio-gel material for a marine fish reef. The bio-gel material is prepared from fly ash, shell powder, an alkali activator, steel slag and water. The invention further provides a preparation method of the bio-gel material for the marine fish reef. The artificial fish reef is prepared from industrial solid wastes such as marine waste shells and fly ash, so that the marine ecological environment is improved, and a favorable place is provided for the diversity of marine organisms.

Description

technical field [0001] The invention relates to the technical field of artificial fish reef construction, in particular to a biological gel material used for marine fish reefs and a preparation method thereof. Background technique [0002] The ocean is rich in resources, which provide many favorable conditions for the birth and reproduction of life. However, due to factors such as environmental pollution in coastal waters, overfishing, and global climate change, the self-purification capacity of the ocean is limited, and coastal biological resources have declined significantly. The decline of marine fishery resources is obvious, and it is imminent to manage and restore the marine environment. Marine ecologists and fishery experts from various countries believe that building marine ranches is an important means to achieve sustainable development of fisheries and restore the marine ecological environment. [0003] Marine ranching is an artificial fishery that uses artificial ...
