The invention discloses a two-box asynchronous concrete freezing-thawing test device and a test method. The device comprises two freezing-thawing test boxes, an anti-freeze liquid cyclic exchange system between the two boxes, a respective two-box heating and cooling system, an automatic control system and a storage system, wherein the anti-freeze liquid cyclic exchange system between the two boxes is connected with the two freezing-thawing test boxes respectively through exchange pipelines; the respective two-box heating and cooling system is connected with the two freezing-thawing test boxes respectively through heating and cooling pipelines; temperature sensors are arranged in the two freezing-thawing test devices; the automatic control system controls connection or disconnection between the exchange pipelines, the heating and cooling pipelines and the two freezing-thawing test boxes respectively according to received temperatures. By the automatic control system, the two freezing-thawing text boxes are respectively in freezing and thawing running states in a cyclic reciprocating manner for asynchronous operation; in the same test amount, the energy consumption is about 30-35 percent of a single text box device; the two-box asynchronous concrete freezing-thawing test device has the characteristics of low energy consumption and low noise.
Description
technical field [0001] The invention relates to a concrete freeze-thaw test device, in particular to a double-box asynchronous concrete freeze-thaw test device and a test method. Background technique [0002] The antifreeze performance of concrete is an important content to evaluate the long-term durability index of concrete. In important concrete projects, almost every concrete proportion that requires antifreeze needs to be tested for antifreeze performance (including proportion design and Construction sampling inspection), so there are a lot of frost resistance tests to be done every year. Concrete antifreeze test equipment is the test equipment used to test the antifreeze performance of concrete, mainly including concrete rapid freeze-thaw test equipment, concrete slow freeze-thaw test equipment and concrete unilateral freeze-thaw test equipment, the most commonly used is concrete rapid Freeze-thaw test equipment. [0003] The existing concrete rapid freeze-thaw test e...
