Cement content can be determined based on the heat produced when the soil-cement sample is neutralized with a buffering solution consisting of sodium acetate and glacial acetic acid. The measured temperature of the soil sample after neutralization is compared to charts found in Kauschiger et al. (1992) to determine the cement content.</p><p><strong>Accuracy and Precision</strong></p><p>Samples of soilcrete spoil can be used to accurately determine the cement content, water content, and clay content of the soilcrete.</p><p><strong> </strong><strong>Adequacy of Coverage</strong></p><p>The number of measurements required to assess the soilcrete spoil are not too expensive or time‑consuming. However, it is recognized that only a very small fraction of the soilcrete is actually tested.</p><p><strong> </strong><strong>Implementation Requirements </strong></p><p>This method is easy to implement, requiring little additional time or equipment.</p><p><strong> </strong><strong>General Comments</strong></p><p>Soilcrete samples can be taken during any jet grouting operations.<strong> </strong></p></p>
