Concrete early-stage crack resistance testing device and using method thereof

Abstract

The invention discloses a concrete early-stage crack resistance testing device and a using method thereof.The concrete early-stage crack resistance testing device comprises a fixed base directly arranged on the ground, a concrete testing bin, a protection cover, a fixing mechanism and a supporting seat, the concrete testing bin is fixedly connected to the middle of the upper end of the fixed base, and the upper end of the protection cover is fixedly connected with a connecting column; the protective cover is arranged above the concrete test bin and is limited above the concrete test bin through the connecting column, the fixed block, the connecting block and the movable block, the fixing mechanism is used for limiting detected concrete in the concrete test bin, and the supporting seat is fixedly connected to the middle of the upper end of the supporting plate in a horizontal state. According to the concrete early-stage crack resistance testing device and the using method thereof, limiting of tested and detected concrete is facilitated, concrete caving during detection is prevented through arrangement of the protection cover, and the concrete in the concrete testing bin can be cleaned very conveniently after the test is finished.

Description

technical field [0001] The invention relates to the related technical field of concrete crack resistance test, in particular to a concrete early crack resistance test device and a use method thereof. Background technique [0002] Concrete refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. Usually, concrete mostly refers to the use of cement as cementitious material, sand and stone as aggregates, and water in a certain proportion. Mixing, the cement concrete obtained by mixing is widely used. However, before the concrete is put into use, it is necessary to test the early cracking resistance of the concrete, so as to ensure the correctness of the ratio of the various components of the concrete in the actual use process. Reasonable analysis provides a basis, so it is necessary to use an early crack resistance test device and its use method; [0003] However, the commonly used concrete early-stage ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a concrete early-stage crack resistance test device and its use method, in order to solve the above-mentioned background technology proposed in the actual use process, in the test, the effect of limiting the concrete is not good, it is easy to cause the concrete to crack During the test, shaking occurs, which affects the accuracy of the actual test results, and the test process is likely to cause dust, and the concrete is prone to collapse. The collapsed concrete slag is likely to cause injury to the testers and affect the health of the testers. After the test is completed, the concrete is cleaned up in time, causing pollution to the inside of the device, and the display of the test results is not intuitive enough.
