Historical (view previous versions of standard)
Significance and Use
This practice is used for making test cylinders or prisms of PA concrete. Cylinders are used for determining compressive strength and approximate density. Prisms, cut from cylinders, eliminate the surface effect and thus more accurately represent the actual density of PA concrete in place.
1.1 This practice covers procedures for making standard test cylinders used to determine the compressive strength and density of preplaced-aggregate (PA) concrete.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
