ASTM C671-94 PDF Download

ASTM C671-94 is a standard test method that focuses on determining the frost immunity of concrete specimens. It specifically measures the length of time that the specimens can endure water immersion before experiencing critical dilation when subjected to a prescribed slow-freezing procedure. In other words, this test method helps determine the resistance of the concrete to freezing conditions and the potential damage that may occur as a result. The test involves immersing the concrete specimens in water and subjecting them to controlled freezing, observing the time it takes for critical dilation to occur. This standard provides a systematic approach for assessing the durability and performance of concrete under freezing conditions, helping engineers and construction professionals make informed decisions regarding concrete selection and design.
