Abstract

The invention relates to the field of civil and architectural engineering, and discloses a pit sand concrete compressive strength detection method and an apparatus thereof. The method comprises the following steps: selecting at least three detection zones, and drilling a core sample with the diameter of 70mm on the structural concrete of each of the detection zones; cutting, rubbing, and carrying out compressive strength test by using a universal material testing machine to obtain the average compressive strength fcor.j of the core samples in the detection zones; and calculating the concrete standard compressive strength equivalent value fcu.j by using a correction coefficient formula. The method and the apparatus enhance the detection adaptability of the compressive strength and improve the detection precision.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a method and device for detecting the compressive strength of mountain sand concrete. Background technique [0002] Concrete strength is the basic basis for evaluating the quality of construction projects. Under normal circumstances, the concrete structure should be in accordance with the requirements of the Reinforced Concrete Engineering Construction and Acceptance Code, and the cubic standard curing test block should be made for the evaluation and acceptance of the concrete strength, but in some special cases (the test of the compressive strength of the test block When the result is doubtful, when there is a concrete quality problem due to poor material, construction or maintenance, when the concrete is subjected to freezing damage, fire, chemical erosion or other damage, when it is necessary to test the strength of the building structure or the concrete in the building that h...
