ASTM C672/C672M-12 PDF Download

The ASTM C672/C672M-12 standard is a test method used to determine the resistance to scaling of a horizontal concrete surface that is exposed to freezing-and-thawing cycles in the presence of deicing chemicals. The purpose of this standard is to qualitatively evaluate the surface resistance by visually examining the concrete.

The test method involves subjecting the concrete surface to a series of freezing-and-thawing cycles while also being exposed to deicing chemicals. The cycles are designed to simulate the conditions that the concrete may be exposed to in real-life scenarios, such as winter conditions with frequent freezing and thawing actions and the use of deicing chemicals on roads and surfaces.

The evaluation is carried out through visual examination of the concrete surface after the testing period. The presence and severity of any scaling, which is the loss of surface mortar or concrete due to freeze-thaw damage, is assessed. This provides an indication of how well the concrete surface can withstand the effects of freezing and thawing cycles in the presence of deicing chemicals.
