Embodiment 1

[0020] Add 30kg of fly ash, 24kg of calcium sulfate, and 15kg of silica fume to 80kg of Portland cement, add 90kg of water, stir evenly, use it as cement, and then use the cement to make cement modules, each with a capacity of 2m 3 , respectively fitted with 0.5m 3 Glutinous rice slurry water (mix 50 catties of glutinous rice flour and 450L of fresh water evenly) and 0.5m 3 In small pools of oxalic acid (concentration 5%), each soaked for 24 hours and dried for use, combined with building materials such as bricks to make a cement pool for cultivating Penaeus vannamei.

Embodiment 2

[0022] Add 3kg of fly ash, 2.4kg of calcium sulfate, and 1.5kg of silica fume to 8kg of Portland cement, add 9kg of water, stir evenly, use it as cement material, and then use the cement to make cement modules, each with a capacity of 2m 3 , respectively fitted with 0.5m 3 Glutinous rice slurry water (mix 50 catties of glutinous rice flour and 450L of fresh water evenly) and 0.5m 3 In small pools of oxalic acid (concentration 5%), each soaked for 24 hours and then dried to make a seaweed attachment frame, which is used for seaweed attachment in seaweed ecosystem restoration.

Embodiment 3

[0024] Add 30kg of fly ash, 24kg of calcium sulfate, and 15kg of silica fume to 80kg of Portland cement, add 90kg of water, stir evenly, use it as cement, and then use the cement to make cement modules, each with a capacity of 2m 3 , respectively fitted with 0.5m 3 Glutinous rice slurry water (mix 50 catties of glutinous rice flour and 450L of fresh water evenly) and 0.5m 3 In the small pools of oxalic acid (concentration 5%), dry after each soaking for 24 hours, and install on the surface of mangrove ecosystem coastal buildings.

[0025] (1) Optimum formula ratio

[0026] In order to verify the optimal ratio of the formula of the present invention, several experimental groups of cement compositions with different ratios of ingredients were set up for seawater-proof building surfaces, and the anti-seawater erosion ability of different experimental groups was tested.

Abstract

The invention discloses a preparation method of seawater corrosion-preventive cement for marine multiplication and cultivation and marine ecological engineering. The preparation method comprises the following steps: mixing silicate cement with pulverized fuel ash, calcium sulfate and silicone powder according to specific proportion to obtain cement, then producing a cement block by utilizing the cement, sequentially soaking the cement block in sticky rice pulp water and oxalic acid respectively for 24 hours, and then drying to obtain corrosive cement. According to the seawater corrosion-preventive cement for marine multiplication and cultivation and marine ecological engineering, the service life of equipment can be effectively prolonged, and the multiplication and cultivation facilities can be protected.

Description

technical field [0001] The invention provides a preparation method of seawater erosion-proof cement for aquaculture enhancement and marine ecological engineering, which can effectively prolong the service life of seawater aquaculture enhancement equipment and ecosystem restoration materials, and protect the aquaculture enhancement facilities and ecological engineering. Background technique [0002] Seawater aquaculture is developing rapidly. A large number of aquaculture aquaculture and marine ecological engineering cement facilities are severely damaged due to seawater erosion, which affects the benefits of aquaculture aquaculture and the ecological restoration effect of marine ecological engineering. Ordinary waterproof cement equipment cannot resist long-term immersion and erosion of seawater, which reduces the service life and use effect of the facility. In order to improve the service life of seawater aquaculture and marine ecological engineering cement facilities and e...
