Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] The method for measuring the damage-resistivity correlation relationship of carbon fiber concrete materials under static loads includes the following specific steps:

[0031]1) Fabrication of standard specimens of carbon fiber concrete: According to the mix ratio design of carbon fiber concrete, the standard specimens of this type of concrete are produced. The size of the standard specimens is 150mm×150mm×150mm. Two pieces of electrode material 4 are inserted opposite to each other at 25mm from one of the pieces. The size of the electrode material is required to be 150mm×175mm. The distance between the electrode material 4 in the carbon fiber concrete specimen is 100mm. The material of the electrode material 4 is 304 stainless steel mesh. , you can also choose stainless steel sheets or carbon fiber cloth; then carry out standard curing on the finished concrete s...

Abstract

The invention provides a measuring method for destruction-resistivity incidence relation of carbon fiber concrete. The measuring method comprises the following steps: manufacturing a standard sample of the carbon fiber concrete, marking a measuring point, measuring ultrasonic wave speed and resistance, measuring the destruction-resistivity incidence relation of the carbon fiber concrete and the like. The method uses normal measuring devices, the operation is simple and convenient, the destruction-resistivity incidence relation of the carbon fiber concrete under the condition of different loadings can be measured, the measuring result is relatively accurate, and a foundation for nondestructive testing of concrete can be laid. Therefore, the measuring method provided by the invention has the comprehensive applicability and the theoretical value during practical engineering.

Description

technical field [0001] The invention relates to a method for measuring the damage-resistivity correlation relationship of concrete materials under load, in particular to a method for measuring the damage-resistivity correlation relationship of carbon fiber concrete materials under static load. Background technique [0002] Filling concrete with a small amount of carbon fiber can improve the durability, tensile strength and flexural performance of concrete materials. Carbon fiber concrete is a multifunctional, intelligent and excellent material with a very broad application prospect. In terms of metal protection, this material can be used as a cathodic protection material; in building structures, this material can be used for heating or building safety monitoring; on some special roads and airport runways, this material can be used to melt ice and snow; in military bunkers And in some communication facilities, the material can be used for electromagnetic shielding, etc. Dur...
