Doplňující informace
| 1. Scope | ||||||||||||||||
|
1.1 This test method covers determination of the density (see Note 0) of freshly mixed concrete and gives formulas for calculating the yield, cement content, and air content of the concrete. Yield is defined as the volume of concrete produced from a mixture of known quantities of the component materials. 1.2 The values stated in either inch-pound or SI units shall be regarded separately as standard. The SI units are shown in brackets. The values stated might not be exact equivalents; therefore each system must be used independently of the other. Note 1--Unit weight was the previous terminology used to describe the property determined by this test method, which is mass per unit volume. 1.3 The text of this test method references notes and footnotes that provide explanatory information. These notes and footnotes (excluding those in tables) shall not be considered as requirements of this test method. |
