Low Concrete Cylinder Strength — What, why, & how

Cylinders are molded from a sample of fresh concrete, cured in standard conditions and tested at a particular age, as indicated in the specification, usually at 28 days. Procedures must be in accordance with ASTM standards. The average strength of a set of 2 or 3 cylinders made from the same concrete sample and tested at 28 days constitutes one

Transporting Concrete Cylinders - The Special Inspector

Feb 27, 2020 · Too many times we have seen concrete cylinders rolling back and forth in the back of a pickup truck, which can be very costly to the developer. In fact, on average, improperly transported cylinders can break up to 15 percent lower than properly transported cylinders. This the percentage could be the determinant of a passing or failing compressive strength, which […]
