ASTM C426-16 PDF Download

ASTM C426-16 is a standard test method that aims to evaluate the drying shrinkage characteristics of concrete masonry units. The results obtained from this laboratory method are utilized in determining crack control provisions for concrete masonry. It is important that the testing laboratory conducting this test method complies with Practice C1093 to ensure accurate and reliable results.

This test method is designed to determine the linear drying shrinkage of concrete masonry units or related concrete units under specific accelerated drying conditions. It provides a standardized procedure for conducting the test in a routine manner. The standard references notes and footnotes that offer additional explanatory information, but these notes and footnotes, except for those in tables and figures, are not considered mandatory requirements.
