ASTM C567/C567M-11 pdf free.Standard Test Method for Determining Density of Structural Lightweight Concrete.
This test method provides procedures to determine the oven-dry and equilibrium densities of structural lightweight concrete.
4. Summary of Test Method
4.1 This test method provides procedures for detennining the oven-dry and equilibrium densities of structural lightweight concrete, by calculation or measurement. The calculated ovendry density is determined from batch quantities and volume of a given hatch of concrete. The calculated equilibrium density is approximated by adding a fixed quantity to the oven-dry density. Measured densities are obtained from determinations of the mass of cylindrical specimens after specified treatments.
11. Precision and Bias
11. 1 Precision—The precision of this test method has not yet been determined, but an industry-wide multilaboratory testing program is being coordinated. The precision statements will be included when the data is compiled and reviewed.
11.2 Bias—Bias for this test method cannot be determined since there is no reference standard available for comparison.
12. Keywords
12. I equilibrium density; lightweight concrete; oven-dry density.
