Sea sand recycled mixed concrete member

Abstract

The invention provides a sea sand recycled mixed concrete member, and belongs to the technical field of concrete members. The member comprises a base and a top plate arranged above the base, the edgeof the upper portion of the base is connected with the top plate through a first side plate and a second side plate, two first baffles and two second baffles are movably arranged at the upper portionof the base, and a rectangular pouring cavity is defined by the two first baffles and the two second baffles. The embodiment has the advantage that the sea sand concrete prefabricating efficiency is high, rust-proof liquid storage parts are arranged on the outer side of the first baffles and the upper portion of a cover plate, and rust-proof liquid can be automatically smeared on the outer surfaces of transverse bars and the outer surfaces of longitudinal bars in the process of inserting the transverse bars and the longitudinal bars into the pouring cavity, so that rust-proof layers are formedoutside the transverse bars and outside the longitudinal bars, chloride ions in the sea sand concrete are prevented from making contact with the transverse bars and the longitudinal bars, the transverse bars and the longitudinal bars are prevented from being rusted, the strength of the sea sand concrete member is improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of concrete components, in particular to a sea-sand recycled mixed concrete component. Background technique [0002] Sea sand is a natural resource with wide distribution and huge reserves. At present, how to use sea sand rationally has attracted widespread attention and research all over the world. Using sea sand as a raw material for preparing concrete can greatly promote the development and utilization of marine resources, alleviate the shortage of river sand, and avoid ecological and environmental problems caused by over-exploitation of river sand, but the chloride ions carried in sea sand will destroy The "passive film" on the surface of the steel reinforcement inside the concrete causes corrosion of the steel reinforcement, which leads to the deterioration of the concrete structure.

Using sea sand as a raw material for preparing concrete can greatly promote the development and utilization of marine resources, alleviate the shortage of river sand, and avoid ecological and environmental problems caused by over-exploitation of river sand, but the chloride ions carried in sea sand will destroy The "passive film" on the surface of the steel reinforcement inside the concrete causes corrosion of the steel reinforcement, which leads to the deterioration of the concrete structure

[0003] In the prior art, most of the anti-corrosion operations for steel bars are manually painted with a layer of anti-rust film on the surface of the steel bars to prevent the chloride ions in the sea sand from directly contacting the steel bars, thereby avoiding corrosion of the steel bars and ensuring the strength of the steel bars inside the concrete , to ensure the strength of sea-sand concrete components. However, the efficiency of artificial anti-rust film is relatively low. After the anti-rust film is applied, it needs to be dried naturally, so it cannot meet the large-scale prefabrication requirements of sea-sand concrete.
