Concrete seawater environment dry-wet cycle test device

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.
