AI Technical Summary

Technical Problem

Existing concrete block compressive strength testing devices suffer from inaccurate measurement results due to stress concentration and changes in ambient temperature and humidity, especially on uneven bearing surfaces and non-parallel upper and lower surfaces. Furthermore, the temperature and humidity conditions of the specimens are easily altered during transfer.

Method used

A flexible interface layer and a spherical bearing structure are used to distribute the load evenly. Combined with temperature and humidity control components, a constant environment is created at the test station to ensure that the test specimens are tested under the same conditions.

Benefits of technology

It eliminates stress concentration, improves the accuracy and consistency of measurement results, avoids the influence of temperature and humidity changes on test results, and adapts to different block surface shapes and heights.
