Do not pour test solution directly onto the specimen. In the case of a unit with an exposed architectural or other nonplanar surface, cut the coupon from another flat molded surface ideally as far as possible from the architectural or other nonplanar face and in no case less than 2 in. Remove the specimen from the container, pourthe rinse water or saline solution through the filter paper, and rinse the specimen container until all residue spall in the specimen container is collected on the filter paper.
Some values have only SI units 1c262 the inch-pound equivalents are not used in practice.
Work Item s – proposed revisions of this standard. Do not saw-cut test specimens from units that have been previously oven dried. Note 6 – Split-faced surfaces are cc1262 most common surfaces used to provide an architectural appearance asmt segmental retaining walls. Report these values for each specimen as well as the average of the specimens tested. This summary attempts to provide the information which is most commonly used, but Allan Block does not claim that all information contained in the standard is represented.
The testing laboratory performing this test method should be evaluated in accordance with Practice C Replace the specimen in the container. Pour the test solution from the specimen container through the filter paper to collect the astj spall from the test specimen. This does not provide a comparison to x1262 performance but a systematic approach to testing.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Immediately following saw-cutting, remove loose particles and residue from the coupon by rinsing in tap water and brushing with a soft bristle brush.
Where the coupon thickness is less than 1. A copy of the full standard is available upon request. Historical Version s – view previous versions of standard. Related concrete units include units such as hollow and solid concrete masonry units, concrete brick, and concrete roof pavers. The following summarizes the contents of ASTM C and key components of the test methods used to determine relative freeze thaw durability.
Each specimen shall bemarked with a unique identification number on the non-molded surface of the specimen. Open containers to visually inspect the condition of the specimens and to adjust the test solution level to comply with 7. Do not subject test specimens to oven-drying prior to completion of freeze-thaw testing. Cut the coupon from the exposed surface of the unit as the unit is used in service unless the exposed surface is an architectural or other nonplanar surface see Note 6.
It is the responsibility of the user of this standard to establish appropriate safety, qstm, and environmental practices and determine the applicability of regulatory limitations prior to use.
Do not fully immerse coupons in water. Remove a single specimen from ast container. Using fingertips and a squeeze bottle, remove loose particles from all surfaces of the specimen, again being careful to collect all rinse water or saline solution and loose particles in the specimen container. Consider any pieces that separated from the specimen as part of the residue.
Immediately rinse the specimen with water if the specimen is tested in saline solution, use saline solutiontorinse the specimen usinga squeeze bottle,being careful to collect in the specimen container the rinse water or saline solution and all loose particles from the specimen.
Related concrete units include units such as d1262 and solid concrete masonry units, concrete brick, and concrete roof pavers. Close the container lid tightly and store the container on f1262 level surface in laboratory air as defined in 6.
Combining values from the two systems may result in non-conformance with this standard. However, other means could be used ast, obtain similar architectural effects like tumbling, grinding, and slumping. Rinse the residue from specimens tested in saline solution three times with water to remove any soluble salt.
Link to Active This link will always route to the current Active atm of the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
The units shall be free from visible cracks or structural defects.
