Maturity Method A Guide to Concrete Strength Giatec

The most common method for monitoring the strength of in-situ concrete is the use of field-cured cylinders. These samples are cast and cured according to ASTM C31, before being tested for compressive strength at various stages, usually by a third-party lab. Typically, if the slab has reached 75% of its designed strength, engineers will give the 'go-ahead' to their team to move on to the
