Embodiment 1

[0042] Example 1: The proportion of ordinary Portland cement concrete, the weight ratio of ordinary Portland cement, gravel, sand, water and polycarboxylate superplasticizer powder is: 17.1%, 46.67%, 29.0%, 7.2% , 0.03%.

[0043] The parent rock of the crushed stone is one of basalt and diabase, and its maximum particle size is no more than 50mm, and the gradation is good; the sand is river sand and machine-made sand (the parent rock is granite, basalt, one) or one or several types of desalinated sea sand with good gradation. The water mentioned should meet the concrete water standard (JGJ63-2006), Cl - Content4.5, little effect on cement initial setting time difference and final setting time, strength and permeability. And the above materials selected in Examples 1-18 are the same.

Embodiment 2

[0044] Embodiment 2: benchmark concrete proportioning, the proportioning by weight of sulphoaluminate cement, crushed stone, sand, water and polycarboxylate superplasticizer powder is successively: 17.1%, 46.67%, 29.0%, 7.2%, 0.03%.

[0045]

[0046] By comparing the above implementations, it can be seen that under the same dosage, the electric flux of sulphoaluminate cement concrete is smaller, indicating that the concrete has good impermeability, and compared with ordinary silicate, its oyster larvae are less likely to adhere to rate increased significantly.

Embodiment 3

[0047] Example 3: The weight proportions of unmodified dark pigment, sulphoaluminate cement, gravel, sand, water and polycarboxylate water reducer powder are: 0.51%, 16.59%, 46.67%, 29.0%, 7.2% %, 0.03%.

Abstract

The invention relates to a technology for inducing adhesion of marine attaching organisms, particularly to environmentally-friendly concrete for inducing adhesion of marine attaching organisms, and apreparation method thereof, and belongs to the field of crossing of marine attaching organisms and marine concrete. The environmentally-friendly concrete comprises the following components: a cementing material, gravels, sand, water, a dark pigment, biological calcium powder, biological calcium carbonate particles, carbonate and a superplasticizer. According to the invention, rapid construction ofengineering can be realized, and the environmentally-friendlyconcrete has high impermeability and high corrosion resistance, especially has high sulfate corrosion resistance, and has significant advantages in ocean engineering and engineering needing rapid repair.

Description

technical field [0001] The invention relates to a technique for inducing marine sessile organisms to adhere, in particular to a green concrete and a preparation method for inducing marine sessile organisms to adhere, and belongs to the cross field of marine sessile organisms and marine concrete. Background technique [0002] Reinforced concrete is widely used in marine infrastructure construction, such as harbor terminals, sea-crossing bridges, ocean platforms and subsea tunnels, etc. However, the corrosion of steel bars caused by chloride ion corrosion greatly shortens the service life of reinforced concrete structures and brings a huge economic burden to society. So far, for reinforced concrete projects in marine environments, representative anti-corrosion technologies mainly include high-performance concrete, surface coatings, FRP bars, steel bar rust inhibitors, and electrochemical protection technologies. These anti-corrosion technologies have some shortcomings or defi...
