Significance and Use
5.1 This test method is used to determine the density of bentonitic slurries in the laboratory and field. For freshly mixed slurry, this test method may be used as an indicator of mix proportions. For in-trench slurry, a certain value may be specified for maintaining trench stability.
1.1 This test method covers the determination of the density of slurries used in slurry construction techniques, such as those used for barriers to control the horizontal movement of liquids. This test method is modified from API Recommended Practice 13B.
1.2 Units—The values stated in SI units are to be regarded as standard, unless other units are also specified, such as density in lbm/ft3 or lbm/gal. No other units of measurement are included in this standard.
