Embodiment Construction

[0026] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the examples.

[0027] Such as figure 1 As shown, a device for measuring the temperature and humidity of concrete specimens under constant axial compression load, including: a loading frame for placing concrete specimens and loading equipment; System; a strain acquisition system used to monitor the screw strain in the pressurized zone and reflect the load maintenance situation.

[0028] The loading frame includes a pressurized base plate 1, a pressurized backing plate 2, a reaction force support plate 3, a screw rod 4 and a nut 5, and the pressurized base plate 1, the pressurized backing plate 2 and the reaction force support plate 3 are all supported by the screw rod 4, and are supported by the screw rod 4. The supporting nut 5 of corresponding position is fixed.

[0029] The concrete specimen to be tested is placed between the

Abstract

The invention discloses a method for measuring the temperature and humidity of a concrete test piece under a constant axial pressure load. According to the method, measurement is carried out under theeffect of a constant axial pressure load. The method has clear steps and is based on the simple principle; and the measurement process is easy to operate. The result demonstrates that the axial pressure load has the obvious impact on the relative humidity of the concrete; and at the moment of load application, the relative humidity increases instantaneously and then decreases slowly.
