Water Absorption (Sorptivity) Testing of Concrete (ASTM C

Molded cylinder specimens are cast from a concrete mixture and moist cured for 28 days (or in accordance with a project specification). A 2-inch (50-mm) slice is taken from the cylinder and placed into an evaporation chamber at 122 °F (50 °C) and 80% relative humidity for three days, then sealed in a container for a minimum of 15 days.

ASTM C39 Concrete Cylinder Compression Testing

ASTM C39 determines the compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a unit weight in excess of 50 lb/ft3 (800 kg/m3). A compressive axial load is applied to molded cylinders or cores until failure occurs. The compressive strength of the specimen is

All COV value preparation methods are lower than the COV of 3.2%, given in ASTM C39 for a 4x8 inch standard cylinder with the exception of the Sulphur Preparation Method. This means the concrete cylinders used in this investigation have constant and high quality in terms of compaction, curing, capping & grinding and crushing.

Overview. Neoprene Pads or Pad Caps are ideal for tests between 1,500 and 7,000psi, but can also be used for concrete strengths up to 12,000psi with proper verification by the user as noted in ASTM C1231. These pads spread the compressive force evenly across specimen surfaces. Durometer hardness of neoprene pads must be matched to the design

Grout 'cubes' vs. Concrete 'cylinders'

As an example, for masonry grout, the ASTM spec for testing requires a 2:1 ration because there was little correlation between cubes and cylinders, but the mold material (absorbent vs. impervious also had a large effect. When you crush a 2:1 cylinder you open up the possibility for a flexural failure rather a compressive failure.
