Problems solved by technology

[0005] The technical problem to be solved by the present invention: after the hardening of the traditional concrete artificial reef, minerals with coarse crystallization and poor cohesion such as calcium hydroxide and ettringite will be enriched between the coarse aggregate and the matrix, resulting in the strength of the artificial reef. It provides a method of using cinder and kaolin calcined as aggregate, mixed with gypsum, cement, etc., and carbonized in the cave environment to obtain concrete artificial reef materials.

example 1

[0017] First weigh 1 kg of coal cinder, add it to a pulverizer and pulverize it for 1 hour, pass through a 50-mesh sieve, collect the sieved material, add the sieved material to a beaker filled with 2L deionized water, soak for 2 days, filter, and collect the filter residue. Then put the filter residue in an oven, dry at 95°C for 1 hour, take out the dried filter residue and put it into a beaker, then add 600g of kaolin, stir and mix for 3 minutes to obtain a mixed powder; then put the above mixed powder in a muffle furnace In the process, the temperature was raised to 1000°C at a rate of 10°C / min, calcined for 2 hours, and the calcined was completed. After the material in the muffle furnace was cooled to room temperature with the furnace, the material was taken out and moved into a ball mill for ball milling for 1 hour, and then passed through a 80-mesh sieve. Collect the sieved material to obtain the calcined material; in parts by weight, weigh 40 parts of the above calcined ...

[0020] First weigh 2kg of coal cinder, add it to the pulverizer and pulverize it for 2 hours, pass through a 55-mesh sieve, collect the sieved material, add the sieved material to a beaker filled with 3L deionized water, soak for 3 days, filter, collect the filter residue, Then put the filter residue in an oven, dry at 100°C for 2 hours, take out the dried filter residue and put it into a beaker, then add 650g of kaolin, stir and mix for 4 minutes to obtain a mixed powder; then put the above mixed powder in a muffle furnace In the process, the temperature was raised to 1050°C at a rate of 13°C / min, calcined for 3 hours, and the calcined was completed. After the material in the muffle furnace was cooled to room temperature with the furnace, the material was taken out and moved into a ball mill for ball milling for 2 hours, and then passed through a 90-mesh sieve. Collect the sieved material to obtain calcined material; in parts by weight, weigh 45 parts of the above calcined mat...

[0023] First weigh 2kg of coal cinder, add it to a pulverizer and pulverize it for 2 hours, pass through a 60-mesh sieve, collect the sieved material, add the sieved material to a beaker filled with 3L deionized water, soak for 3 days, filter, and collect the filter residue. Then put the filter residue in an oven, dry at 105°C for 2 hours, take out the dried filter residue and put it into a beaker, then add 700g of kaolin, stir and mix for 5 minutes to obtain a mixed powder; then put the above mixed powder in a muffle furnace In the process, the temperature was raised to 1100°C at a rate of 15°C / min, calcined for 3 hours, and the calcined was completed. After the material in the muffle furnace was cooled to room temperature with the furnace, the material was taken out and moved into a ball mill for ball milling for 2 hours, and then passed through a 100-mesh sieve. Collect the sieved material to obtain the calcined material; weigh 50 parts of the above calcined material, 4 part...

Abstract

The invention discloses a preparation method of a concrete artificial fish reef material, and belongs to the technical field of artificial fish reef preparation. The preparation method comprises the steps that firstly, pretreated coal slag and clay are mixed and calcined; then, obtained materials are mixed with gypsum and the like; then, the mixture is added into a mold and is subjected to primary maintenance in solution cavity environment; carbon dioxide in a solution cavity takes a reaction with sodium hydroxide generated in the materials to generate calcium carbonate, so that the alkalinity is reduced; calcium hydroxide and ettringite are reduced; the materials are demolded to obtain fish reef concrete; then, a mixed solution prepared by chitosan and the like is sprayed and coated on the surface of the concrete; maintenance is performed again to obtain the concrete artificial fish reef material. The preparation method solves the problems of low artificial fish reef intensity, poor durability, short service life and the like. The obtained concrete artificial fish reef material has high intensity and higher durability; the hardened concrete artificial fish reef material has good compactness; the finally coated chitosan and mussel mucoprotein can be used as microorganism growth nutrient substances; the microorganism attachment quantity is increased.

Description

technical field [0001] The invention relates to a method for preparing a concrete artificial fish reef material, and belongs to the technical field of artificial fish reef preparation. Background technique [0002] Artificial fish reefs are structures artificially set up in the sea. The purpose is to improve the ecological environment of the sea area, create a good environment for marine organisms to inhabit, and provide places for fish to reproduce, grow, feed and shelter enemies, so as to achieve protection, multiplication and The purpose of increasing catches. At present, the construction of artificial reefs has been widely carried out at home and abroad, and the restoration of offshore marine habitats and fisheries has been carried out, and good results have been achieved. [0003] Artificial fish reefs are mostly built with natural stones, bricks, plants and other raw materials. Later, waste cars, tires, ships, oil tanks, etc. were widely used in the construction of ar...
