Abstract

The invention discloses a testing device and method for an absorption coefficient of a concrete type material. The testing device comprises a digital display dynamometer, a rope, a hook, a water inlet pipe, a computer, a test piece and a water container; the upper part of the rope is connected with the digital display dynamometer, the digital display dynamometer is connected with the computer, and the lower part of the rope is connected with the upper part of the test piece via the hook; when the test piece is lifted via the hook and the rope, the surface of the lower part of the test piece and the upper edge of the water container are located on the same height, or the surface of the lower part of the test piece is slightly lower than the upper edge of the water container. The testing device disclosed by the invention is simple in structure, all the parts are easy and feasible to assemble. In the invention, the computer is used for monitoring and obtaining a value of tensile force borne in real time by the test piece, absorption heights corresponding a continuous time can be obtained through calculation, and thus, a more accurate absorption coefficient is obtained. By using the method, a plurality of test pieces can be tested at the same time, the computer is used for monitoring the change of a value of the force in real time, and more accurate experimental data can be obtained while time and labor are saved.

Description

technical field

[0001] The invention belongs to the technical field of civil engineering material testing, and relates to a testing device and method for the water absorption coefficient of concrete materials. Background technique

[0002] High-performance concrete has gradually become a civil engineering material that has attracted much attention, and durability is one of the most important characteristics of high-performance concrete. As an important index to characterize the material transport performance inside concrete, the water absorption coefficient has scientific significance and necessity for the durability evaluation of materials and the research of materials science.

[0003] When there are many test samples, it is difficult to accurately obtain the test data corresponding to the continuous time by using the existing water absorption coefficient test method, and it is time-consuming and labor-intensive, resulting in large measurement errors.
