Canada require routine sampling of concrete and fabrication of standard molded cylinders. These cylinders are usually cast from a concrete sample taken from the discharge of a truck or a batch of concrete. They are molded and cured following the standard procedures of ASTM C31/C31M and tested as required by ASTM C39/C39M. If the concrete is so

ASTM C39 section 6 goes more into depth about the specifications of the machine's individual parts. Calipers or Ruler - Measuring the diameter of each cylinder is vital to the test results, as you will need to calculate the area of the cylinder to find the strength. Keeping a daily record of your cylinder diameters is recommended.

A.: According to ASTM C 192, "Making and Curing Concrete Test Cylinders in the Laboratory," test cylinders for structural lightweight concrete can be moist cured from the time of molding until the time of testing, or the procedures of ASTM C 567, "Unit Weight of Structural Lightweight Concrete," can be followed.

The cylinders are immediately placed where they are going to stay until the concrete sets up. During this phase, what C 31 calls initial curing, the cylinders can stay in this location for up to 48 hours, but must be kept at a temperature between 60° and 80° F and in a moist environment. C 31 gives us several ideas on ways to achieve this ...
