ASTM D1632-17e1 PDF Download

ASTM D1632-17e1 is a standard practice that provides instructions for making and curing soil-cement compression and flexure test specimens in the laboratory. The purpose of this practice is to ensure accurate control of quantities of materials and test conditions during specimen preparation.

This practice is specifically designed for soil-cement specimens that are to be tested for compressive and flexural strength. It references other ASTM test methods (D1633, D1634, D1635) for conducting these strength tests.

It should be noted that this practice does not apply to soil-cement specimens prepared in commonly available molds of specific dimensions. In such cases, other ASTM test methods (D559 or D560) should be used for sample preparation, and compressive strength testing should be conducted in accordance with Method A of Test Method D1633.

The standard emphasizes the importance of professional judgment and the consideration of unique project circumstances. It states that the standard is not intended to replace the standard of care by which the adequacy of a given professional service must be judged. It also includes a note highlighting that the quality of test results depends on the competence of personnel, equipment suitability, and compliance with other applicable ASTM practices.

Furthermore, the standard provides guidance on the use of units of measurement. It specifies the use of the gravitational system of inch-pound units and states that the pound (lbf) represents a unit of force (weight) while the unit for mass is slugs. However, it acknowledges that the use of pounds to represent both mass and force is common in the engineering/construction profession. It also addresses significant digits and rounding guidelines for observed and calculated values, referencing Practice D6026.
