ASTM D4832-16e1 PDF Download

ASTM D4832-16e1 is a standard test method that provides guidelines for the preparation, curing, transporting, and testing of controlled low-strength material (CLSM) test cylinders. This test method aims to replicate the "field cure" conditions of CLSM under field conditions. The resulting compressive strength test data obtained from the cylinders can be used for acceptance testing, checking mixture proportions for strength, quality control, determining the suitability of CLSM for service, and evaluating the adequacy of curing.

CLSM is commonly used as backfill material around structures, especially in confined or limited spaces. Compressive strength testing is performed during the mix design process and as a quality control measure during construction. The test age and compressive strength values may vary depending on the specific requirements of the end product. The standard also mentions other quality control tests that can be used in conjunction with this test method, such as Practice D5971 and Test Methods D6023, D6024, and D6103.

It is worth noting that this test method can be applied to various mixtures of soil, cement, fly ash, admixtures, and other materials, depending on the intended use, material availability, and placement requirements. The reliability and accuracy of the results obtained from this standard depend on the competency of personnel conducting the test and the suitability of the equipment and facilities used.

Lastly, the standard provides additional information on the significance of the results, compliance criteria, and the use of significant digits and rounding as outlined in related ASTM practices. It also states that the standard uses inch-pound units based on the gravitational system of measurement.
