| Significance and Use | ||||||
|
5.1 This test method is used to determine the amount of sand by volume in bentonitic slurry. The significance of this test method mainly relates to bentonitic slurries used for concrete wall construction. The range of measurement is too limited for use in cement bentonite wall construction. 1.1 This test method covers the
determination of the sand content of bentonitic slurries used in
slurry construction techniques. This test method has been modified
from API Recommended Practice 13B.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The SI units are given in brackets. 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. |
