ASTM D5860-95 (R2013) PDF Download

The ASTM D5860-95 (R2013) standard is a test method used to evaluate the effect of water repellent treatments on the freeze-thaw resistance of hydraulic cement mortar specimens. It is designed to compare the effectiveness of water repellent treatments under freezing and thawing conditions.

The standard requires the use of specific equipment such as a balance, corrosion-resistant aluminum metal pan, weight per liter (gallon) cup, freezing chamber, forced draft oven, and a stiff-nylon-bristled brush.

The test procedure involves treating or immersing the mortar specimens with a water repellent material, allowing them to cure, and then subjecting them to multiple cycles of freezing and thawing.

Periodic weighing and 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 serves as a laboratory screening method for treatment selection and may not accurately reflect the performance of treated and untreated specimens in the field. Additionally, it is not intended to replicate field conditions.
