Description

3.503J concrete resiliometer

Technical Field

The invention belongs to the technical field of concrete resiliometers, and particularly relates to a 3.503J concrete resiliometer.

Background

The existing concrete resiliometer has several types of 2.207J, 4.5J, 5.5J and the like, the intensity of the 2.207J resiliometer under 40Mpa is accurate, the whole test value of the 4.5J is high, the whole test value is inaccurate, and the intensity of the 5.5J resiliometer under 60Mpa-100 Mpa is accurate, so that the existing concrete resiliometer has a certain inaccurate test area, and a resiliometer with a new specification needs to be developed to improve the test accuracy.
