AI Technical Summary
The unstable positioning of the pad in traditional early-stage concrete crack resistance testing devices leads to poor repeatability of test results, affecting the reliability of crack resistance performance assessment.
A combined concrete early crack resistance test device is designed. By setting pad grooves and guide slides on the side plates, the pads are ensured to be placed stably on the curved surface structure to avoid displacement. Upper and lower pads and guide sliders are used for limiting the position.
This improved the accuracy and repeatability of the test results, ensuring the reliability of the crack resistance performance assessment.
