Cement concrete oyster attachment substrate with rough surface and preparation method thereof

Abstract

The invention relates to an oyster attachment substrate technology, in particular to a cement concrete oyster attachment substrate with a rough surface and a preparation method, and belongs to the crossing field of marine sessile organisms and marine concrete. The attachment substrate comprises the following components: a cementing material, a light coarse aggregate, a light fine aggregate, water,dark pigment, biological calcium powder, calcium carbonate powder, trace elements, chopped fibers and a superplasticizer. According to the invention, dilute acid modification and composite grinding technologies are adopted; the inducibility of bovine bone meal is fully exerted, the mixing amount of the bovine bone meal is greatly reduced, anti-corrosion treatment and modification are carried out,a composite inducer with the bovine bone meal as the main component is achieved, the mixing amount is small, the strength and permeability of concrete are hardly affected, meanwhile, the oyster larvaadhesion capacity is very high, and the mildewing problem of the concrete is solved. Compared with concrete without an inducer, the concrete doped with the inducer has the advantage that the attachment number of oyster larvae is obviously increased.

Description

technical field [0001] The invention relates to an oyster attachment base technology, in particular to a rough-surfaced cement concrete oyster attachment base and a preparation method thereof, which belong to the cross field of marine sessile organisms and marine concrete. Background technique [0002] With the improvement of people's living standards, oysters, as a healthy delicacy on the table, have an increasing demand for consumption. Traditional small-scale farming and farming methods can no longer meet the growing demand for oysters. At the same time, with the increase in the restoration of oyster reefs and the upcoming construction of marine ecological engineering for oyster reefs, the demand for oyster attachment substrates is increasing. Common culture methods include bamboo planting culture, bottom sowing culture, strip stone and standing stone culture, hanging culture, etc., but the problem is that it takes a long time for oysters to achieve a satisfactory attach...

AI Technical Summary

Problems solved by technology

[0024] The purpose of the present invention is to solve the problem of the release of a large amount of alkali contained in the attachment base due to the lack of water consumption control and maintenance (the water-cement ratio and the maintenance determine the permeability of the concrete), so that the alkalinity of the seawater in contact with it increase, inhibit the attachment of marine sessile larvae, and at the same time, due to the large amount of shell powder mixed in, the color of the cement attachment base will change from dark gray to light, which is not conducive to the problem of oyster attachment. Lightweight concrete adhesive base that adheres densely to the concrete surface and has good durability
