Concrete seawater environment dry-wet cycle test device

Abstract

The invention discloses a concrete seawater environment dry-wet cycle test device. The concrete seawater environment dry-wet cycle test device comprises a dry-wet cycle test box system, a liquid storage system, a master control box and an air compression system. The dry-wet cycle test box system is connected with the liquid storage system through a solution circulation system and connected with the air compression system through a blow pipeline. The master control box controls the dry-wet cycle test box system, the liquid storage system, the air compression system and the solution circulation system. The device is high in automation degree, easy and convenient to operate and convenient to control, solves the problem that solute deposits in existing equipment, and can be widely applied to the concrete dry-wet cycle test in a simulated seawater environment.

Description

technical field [0001] The invention relates to a concrete seawater environment dry-wet cycle test device, which belongs to the technical field of concrete durability research devices. Background technique [0002] Reinforced concrete structures have been widely used in various engineering fields due to their abundant raw materials, low price, and superior mechanical properties: construction engineering, transportation and bridge engineering, seaport and water conservancy engineering, underground engineering, and some special structures. Among them, the marine environment is relatively complex and harsh, and a large amount of ionized salt in seawater will cause serious damage to reinforced concrete structures. Existing studies have shown that the dry-wet cycle process will accelerate the intrusion of harmful media such as chloride salts and sulfates into the concrete, and at the same time cause changes in the water content of the concrete, resulting in premature failure of t...
