Abstract
This test method details the standard procedure for evaluating the effect of water repellent treatments on the freeze-thaw resistance of hydraulic cement mortar specimens. This test method is designed to compare the effectiveness of water repellent treatments under conditions of freezing and thawing only, intended as a laboratory screening method for treatment selection and may not accurately reflect the performance of treated and untreated specimens in the field. This procedure requires the use of a balance, corrosion-resistant aluminum metal pan, weight per litre (gallon) cup, freezing chamber, forced draft oven, and stiff-nylon-bristled brush. Mortar specimens are treated with or immersed in a water repellent material, removed, and allowed to cure. After air drying, the treated specimens are weighed then subjected to various cycles of freezing and thawing. Periodic weighing and observations are made to determine weight loss and deleterious effects such as spalling and cracking.
Scope
1.1 This test method covers a procedure for determining the comparative effect of water repellent treatments on the freeze-thaw cycling of hydraulic cement mortar specimens.
1.2 This test method is designed to compare the effectiveness of water repellent treatments under conditions of freezing and thawing only. This test method is intended as a laboratory screening method for treatment selection and may not accurately reflect the performance of treated and untreated specimens in the field. This test method is not intended to duplicate field conditions.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
