Shengtuo Testing announced on February 13, 2017: The company has recently won an invention patent and a patent certificate issued by the State Intellectual Property Office of the People's Republic of China. No .: ZL 2014 1 0078642.3.
The invention discloses a method for detecting the elastic modulus of a concrete material in a reinforced concrete component, which includes the following steps:
1. Wave speed detection step: Use one of the single-surface reflection method, single-surface propagation method, double-side transmission method, or surface wave method to detect the propagation speed of impact elastic waves in reinforced concrete members;
2. Elastic modulus calculation steps: Calculate the dynamic tangent elastic modulus of the reinforced concrete member according to the propagation velocity of the impact elastic wave in the reinforced concrete member;
3. Correction step: Correct the dynamic tangent elastic modulus of the reinforced concrete member to obtain the static elastic modulus of the concrete material in the reinforced concrete member.
The advantage of the present invention is that a correction step is added. The correction step is used to eliminate the influence of the reinforcing bar on the elastic modulus detection to obtain the elastic modulus of the concrete material, thereby more accurately evaluating the safety of civil and building structures.
