Abstract

The invention belongs to the technical field of concrete test piece performance tests, and particularly relates to a concrete test piece side length measuring method and device. The method for measuring the side length of the concrete test piece comprises the following steps: taking three reference planes, namely an X plane, a Y plane and a Z plane; taking a reference point A, a reference point B and a reference point C; respectively measuring the distance between the point A and the X plane, the distance between the point B and the Y plane, and the distance between the point C and the Z plane; placing the concrete test piece on the Z plane; attaching the two side walls of the concrete test piece to the X plane and the Y plane, the side face, opposite to the X plane, of the concrete test piece is set as an X' face, the side face, opposite to the Y plane, of the concrete test piece is set as a Y' face, and the side face, opposite to the Z plane, of the concrete test piece is set as a Z' face; respectively measuring the distance between the point A and the X' face, the distance between the point B and the Y' face, and the distance between the point C and the Z' face, subtracting the distances between the reference points and the reference planes from the distances between the reference points and the side faces of the concrete test piece, and averaging to obtain the side length size of the concrete test piece.

Description

technical field [0001] The invention belongs to the technical field of concrete test piece performance test, and more specifically relates to a method for measuring the side length of a concrete test piece and a measuring device. Background technique [0002] The compressive strength index of concrete is the most important strength index. It is generally stipulated that the compressive strength of concrete shall be measured with cube-shaped concrete specimens, and it shall be used as the basis for evaluating the strength grade of concrete. Due to the influence of the size and height of the test piece, the maximum force value for crushing the test piece is different, and the calculated compressive strength value is also different. Therefore, before performing the compressive strength test on the concrete test piece, it is necessary to accurately measure the concrete test piece. size. At present, vernier calipers are mostly used to measure the side length and height of concr...
