Concrete surface coating single-sided freeze-thaw test device

Abstract

The invention discloses a concrete surface coating single-sided freeze-thaw test device, which comprises: a freeze-thaw box, wherein the freeze-thaw box is internally provided with a water cavity andan anti-freezing solution cavity which are not communicated with each other; a water control system communicated with the water cavity; a freezing and thawing circulation system communicated with theanti-freezing solution cavity; a pressure applying system pressed on the upper end surface of the freeze-thaw box; and a base and a spherical seat, wherein a spherical groove is formed in the upper end surface of the base, the lower end of the spherical seat is spherical, the upper end of the spherical seat is a plane, one end of the spherical surface is arranged in the spherical groove of the base in an attached mode, a sample is placed on the plane at the upper end of the spherical seat, wherein a sealing groove is formed in the lower end face of the freeze-thaw box, a sealing ring is installed in the sealing groove, the lower end face of the freeze-thaw box is pressed on a coating on the upper end face of a sample, an open opening is formed in the bottom of the water cavity and directlyfaces the coating, and the sealing ring is located on the periphery of the open opening. A freeze-thaw cycle test is carried out, the frost resistance of the concrete coating is detected, the effectis remarkable, and the concrete surface coating single-sided freeze-thaw test device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of concrete surface coating tests, in particular to a single-sided freeze-thaw test device for concrete surface coatings. Background technique [0002] Considering that there is currently no single-sided freeze-thaw test device for concrete coatings, and the current requirements for the anti-freeze performance of physical buildings are getting higher and higher, especially in the northern coastal areas, for new coatings of physical buildings or projects that have been in operation for decades There is no good equipment to assist in the detection of antifreeze performance of coatings. [0003] Application number: 201710733142.2, application date: 2017-08-24 discloses a concrete freeze-thaw test device and test method, including a test box, the test box includes an upper storage room and a lower storage room; the isolation plate is fixed with a third hydraulic cylinder; the telescopic end of the third hydraul...
