6 Ways to Test Concrete Strength Measurement and 1 You

2021-6-11  The most common method for monitoring the strength of in-situ concrete is the use of field-cured cylinders. This practice has remained generally unchanged since the early 19 th century. These samples are casted and cured according to ASTM C31 and tested for compressive strength by a third-party lab at various stages.
