Concrete specimen curing room and its humidity adjustment method

Abstract

The invention discloses a concrete sample curing room and a humidity adjusting method thereof, and solves the problem that the humidity in a large-sized curing room is non-uniform. The key points of the technical scheme lie in that a spray pipe encircles the periphery of the curing room and the interiors of the spray pipe on the periphery are communicated with each other; a plurality of air outlets are formed in the spray pipe; a plurality of humidifying devices and a plurality of dehumidifying devices are arranged in a one-to-one correspondence manner and positioned on the periphery of the curing room; each of the humidifying devices and the corresponding dehumidifying device are defined as a humidity adjusting component; a plurality of humidity detection elements are arranged to be in one-to-one correspondence with the humidity adjusting components; a control terminal controls the start and stop of the humidity adjusting components corresponding to the humidity detection elements at all positions according to humidity conditions detected by the humidity detection elements. According to the concrete sample curing room and the humidity adjusting method thereof, the humidity in the curing room can be adjusted adaptively, so that the humidity in the large-sized curing room can be in a more uniform state, and the test on a concrete sample can be facilitated.

Description

technical field [0001] The invention relates to the control of the test environment of concrete specimens, in particular to a concrete specimen curing chamber and a humidity adjustment method thereof. Background technique [0002] With the continuous development of concrete technology and the use of high-performance concrete and admixtures, people's attention to the long-term deformation performance of concrete materials has gradually increased, and many test indicators for the long-term performance of concrete have gradually become familiar to people, such as: concrete shrinkage performance , Concrete plastic shrinkage performance, concrete dry shrinkage performance, concrete creep performance and so on. [0003] The effective testing of these indicators plays a decisive role in the accurate judgment of concrete performance. In the process of testing concrete deformation performance indicators, the problem of the test environment should be solved first. Whether the relativ...

Problems solved by technology

[0005] In order to improve the efficiency of the test, the curing room will be set larger to facilitate the placement of more concrete specimens. At the same time, concrete specimens are placed in the entire curing room, and the above-mentioned scheme can be used in a large curing room. Humidity can be controlled, but it can only be roughly controlled. The overall control accuracy is low, and it is easy to have humidity differences in different areas of the room. In addition, the environment of the concrete specimens in the same curing room still has certain deviations, resulting in inaccurate detection of various performance indicators, so there is a certain room for improvement
