Mortar for inducing sessile organisms on underwater oceanographic engineering surface and preparation method

Abstract

The invention relates to a cement mortar technology for inducing adhesion of marine sessile organism, in particular to mortar for inducing sessile organisms on an underwater oceanographic engineeringsurface and a preparation method, belonging to the crossing field of the marine sessile organisms and ocean engineering mortar. The mortar comprises the following components: a cementing material, sand, water, a dark pigment, biological calcium powder, calcium carbonate powder, trace elements, a flocculating agent, a micro-expanding agent and a superplasticizer. The mortar for inducing the sessileorganisms on the underwater oceanographic engineering surface has the characteristics of capability of rapidly inducing the adhesion and metamorphosis of the sessile organisms and promoting the long-term growth of the sessile organisms, and also has the effect of solving engineering problem under seawater through land construction. The mortar can be applied to newly-built marine protects, especially a large number of projects in service in the ocean. Therefore, the corrosion prevention application of the marine sessile organisms in the served reinforced concrete structure is greatly expanded,and the marine sessile organisms can be widely applied to marine ecological environment restoration engineering.

Description

technical field [0001] The invention relates to a cement mortar technology for inducing sessile organisms to adhere to, in particular to a mortar used for inducing sessile organisms on the surface of marine engineering and a preparation method thereof, which belongs to the cross field of marine sessile organisms and marine engineering mortar. Background technique [0002] In the anti-corrosion technology of marine concrete structures, surface coating protection has become the most commonly used marine anti-corrosion technology because of its economy and practicability. However, for the marine concrete structures in the tidal range area and the full immersion area, the general mortar cannot meet the requirements because the tide is in a wet state or is always submerged in water. Therefore need a kind of mortar that can directly pour directly in seawater. Currently, underwater mortars such as polyester resin systems, vinyl resin systems, and epoxy resin systems have been deve...

Problems solved by technology

Marine ecological restoration is urgently needed to solve ecological deterioration, and the anti-corrosion measures in the tidal range area and underwater area of ​​marine concrete projects have limited effects, short service time, and high cost.
