Abstract

The invention discloses a concrete sample temperature anti-crack test device. The device comprises a temperature expansion loading assembly for shaping concrete samples, a maintenance device for maintaining the concrete samples, and an intelligent detection and monitoring system for detecting anti-crack performance of the concrete samples and monitoring the maintenance device. The temperature expansion loading assembly comprises a temperature expansion annular inner mold, an annular outer mold and a base plate. An annular space is formed between the temperature expansion annular inner mold andthe annular outer die mold. According to the test device, through setting of the temperature expansion loading assembly, the maintenance device and the intelligent detection and monitoring system, aconcrete sample temperature anti-crack test under a temperature effect condition can be carried out effectively and rapidly. The invention also discloses a concrete sample temperature anti-crack testmethod. According to the test method, the anti-crack test of the concrete samples under the effect of the temperature can be carried out accurately and reliably.

Description

technical field

[0001] The invention belongs to the technical field of concrete test piece temperature crack resistance test, in particular to a concrete test piece temperature crack resistance test device and test method. Background technique

[0002] Concrete cracking is a key factor affecting the durability of concrete, and has a very important impact on the service life of concrete structures. Cracking is a common problem in concrete engineering. The traditional test evaluation method can only evaluate the resistance of concrete by single factor test results such as compressive strength, tensile strength, elastic modulus, ultimate tensile value, drying shrinkage, creep, and adiabatic temperature rise. Crack performance, crack resistance performance calculation formula is various, it is difficult to accurately evaluate the crack resistance performance of concrete. Therefore, it is of practical significance to study the evaluation method of concrete crack resistance. [...
