Standard Test Method for Cement Content of Hardened Soil-Cement Mixtures

Importancia y uso:

5.1 This test method determines cement content in mixtures of cement with soil or aggregate by chemical analysis. It was developed primarily for testing samples for which a significant degree of cement hydration or hardening has taken place. Test Methods D2901 or D5982 may be used for determining cement content of freshly mixed soil-cement mixtures.

5.2 This test method is based on determination by chemical analysis of the calcium oxide (CaO) content of the sample. The method may not be applicable to soil-cement materials containing soils or aggregates which yield significant amounts of dissolved calcium oxide (CaO) under the conditions of the test.

Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing and sampling. Users of this standard are cautioned the compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors: Practice D3740 provides a means of evaluating some of these factors.

Note 2: Analysis using X-ray fluorescence in accordance with C114 may also be used for determination of calcium oxide (CaO) content of hardened soil-cement.
