Standard Test Method for Determining Density of Structural Lightweight Concrete
SCOPE
1.1 This test method provides procedures to determine the oven-dry and equilibrium densities of structural lightweight 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.
1.3This 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.
