ASTM D5860-95 (R2022) PDF Download

The ASTM D5860-95 (R2022) standard is a test method that evaluates the effect of water repellent treatments on the freeze-thaw resistance of hydraulic cement mortar specimens. The purpose of this standard is to compare the effectiveness of various water repellent treatments under freezing and thawing conditions. It is intended as a laboratory screening method for treatment selection and may not accurately represent the performance of treated and untreated specimens in real-world conditions.

The procedure involves treating mortar specimens with a water repellent material and allowing them to cure. After air drying, the treated specimens are weighed and subjected to cycles of freezing and thawing. Throughout the testing process, observations are made to determine weight loss and any deleterious effects such as spalling and cracking.

It is important to note that this test method does not attempt to replicate field conditions and should be used as a preliminary screening tool for treatment selection. Therefore, the results obtained from this standard may not be directly applicable to the performance of water repellent treatments in actual field applications.
