ASTM C192/C192M-19 PDF Download

ASTM C192/C192M-19 is a standard practice that provides standardized requirements for the preparation of materials, mixing of concrete, and making and curing of concrete test specimens in the laboratory. The practice emphasizes the need for careful and knowledgeable handling of materials, as well as precise control of test conditions to ensure accurate results.

The standard outlines the purposes for which the specimens may be used, including mixture proportioning for project concrete, evaluation of different mixtures and materials, correlation with nondestructive tests, and providing specimens for research purposes. It also highlights the importance of the results obtained from the specimens, as they are widely used for acceptance testing in projects, research evaluations, and other studies.

The practice describes the procedures for making and curing test specimens of concrete, including the use of rodding or vibration for proper consolidation. It emphasizes the need for accurate control of materials and test conditions to ensure the reliability and reproducibility of test results.
