Problems solved by technology

The current concrete unilateral rapid freeze-thaw test chamber usually puts the concrete specimen soaked in the solution into the test chamber, and the time is refrigerated through the refrigeration cycle system. However, the existing concrete unilateral rapid freeze-thaw test chamber The temperature of the cooling water is not uniform, and the temperature difference between the upper and lower sides is large, so the temperature of the solution in the test piece box cannot be guaranteed to be consistent.

Abstract

The invention provides a concrete unilateral rapid freeze-thaw test box, which includes a box body, a box cover and a control panel. A partition is horizontally arranged in the middle of the box. The top of the partition is a test chamber, and the bottom is an equipment chamber. There is a support frame for placing concrete test blocks inside, and a water inlet and a water outlet are respectively opened on the partition. The water inlet and water outlet are respectively located on both sides of the support frame, and a water barrier is set between the support frame and the liquid outlet. , a condenser, a compressor, a heat exchanger and a circulating water pump are arranged in the equipment cavity, a number of magnetic stirrers are arranged on the upper surface of the partition, and a base for rotating the magnetic stirrer is arranged under the partition. The concrete unilateral rapid freezing-thawing test chamber of the invention has a high degree of automation, reduces errors caused by man-made links, and makes the test results more scientific and accurate.

Description

technical field [0001] The invention belongs to the technical field of detection, in particular to a concrete unilateral rapid freeze-thaw test chamber. Background technique [0002] Experts from the Chinese Academy of Engineering have pointed out through a large number of investigations and studies that the average life span of construction projects in my country is less than 30 years. The main reason is that the durability design standards of engineering structures and buildings in my country are too low. Sulfate mainly interacts with concrete physically and chemically to guide the corrosion of concrete materials; sulfate corrosion is one of the important factors affecting the durability of concrete structures. [0003] Concrete unilateral rapid freeze-thaw test chamber is mainly used for the durability design of various concrete projects such as marine engineering, hydraulic engineering, bridges, tunnels, industrial and civil buildings, and to test the frost resistance of...
