High-temperature-resistance and freezing-resistance test device for concrete

Abstract

The invention discloses a high-temperature-resistance and freezing-resistance test device for concrete. The high-temperature-resistance and freezing-resistance test device comprises a closed box body, wherein a heat preservation layer is arranged on the inner surface of the closed box body; a controller, a refrigeration air supply mechanism and a mounting frame are arranged at the top of the closed box body; an air volume rotary adjustment mechanism and at least four freeze-thawing test systems uniformly arranged at the periphery of the air volume rotary adjustment mechanism are arranged in the closed box body. The high-temperature-resistance and freezing-resistance test device can automatically finish a test on the high-temperature resistance and the freezing resistance of the concrete and simulate the bearing conditions of the concrete under various temperature conditions, has the advantages of automatic operation, energy conservation, environment friendliness, precise test data and the like, and can provide precise data for high-temperature resistance and freezing resistance of the concrete in research and detection processes, so that different types of concrete with high performance can be provided for different districts for civil engineering construction.

Description

Technical field [0001] The invention relates to a building material test instrument, in particular to a test device for high temperature resistance and frost resistance of concrete. Background technique [0002] As we all know, concrete is the building structure material with the largest amount and the widest application range, and it is widely used in buildings, subways, bridges, highways and pipelines. As concrete is used more and more widely, higher requirements are put forward on concrete. Concrete will be damaged by various factors during use. Concrete determines the service life of the project. Therefore, more and more people pay more attention to the performance of concrete. High temperature resistance and frost resistance are important indicators of concrete performance. In order to test the durability of concrete specimens, it is necessary to simulate the changing environment of cold and warm throughout the year to test the concrete specimens. This is called a freeze-th...

Problems solved by technology

At present, the equipment used in the freeze-thaw test in the laboratory cannot ensure uniform temperature, and the temperature adjustment is relatively cumbersome, so it is difficult to obtain accurate test data
