In addition, several samples should be obtained daily and tested at different ages to ensure conformance to the specifications. This testing should include measurements of the grout density to ensure that adequate densities have been achieved (based on preconstruction laboratory studies).</p><p><strong>Accuracy and Precision</strong></p><p>This method is accurate and precise.</p><p><strong> </strong><strong>Adequacy of Coverage</strong></p><p>Each mix only needs to be sampled once to determine whether the grout is adequate.</p><p><strong> </strong><strong>Implementation Requirements </strong></p><p>Grout slurry samples are not difficult to obtain.</p><p><strong> </strong><strong>General Comments</strong></p><p>Grout slurry samples should be taken during all jet grouting operations.</p></p>
