Standard Test Method for Determining Density of Structural Lightweight Concrete

SIGNIFICANCE AND USE
The measured or calculated equilibrium density of structural lightweight concrete determines whether specified density requirements have been met. Unless otherwise specified, determine equilibrium density by calculation using the procedures in 9.2.
Test Method C 138/C 138M shall be used to determine the density of freshly mixed lightweight concrete for compliance with concrete placement specifications.
Note 1—The fresh density of lightweight aggregate concrete is a function of mixture proportions, air content, water demand, and the specific density and moisture content of the lightweight aggregate. Decrease in density of a specific lightweight concrete is due to moisture loss that, in turn, is a function of aggregate moisture content, ambient conditions, and the ratio of the surface area to the volume of the concrete member. For most structural lightweight concretes, equilibrium density is approached at about 90 days. For most high-strength lightweight concretes, equilibrium density is approached at about 180 days. Extensive tests demonstrate that despite variations in the initial moisture content of lightweight aggregate, the equilibrium density will be approximately 50 kg/m3  (3.0 lb/ft3) greater than the oven-dry density.
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.
