Standard Test Method for Abrasion Resistance of Concrete or Mortar Surfaces by the Rotating-Cutter Method — 4 стр.
Значение и использование

This test method gives an indication of the relative wear resistance of mortar and concrete based on testing of cored or fabricated specimens. This test method has been successfully used in the quality control of highway and bridge concrete subject to traffic. Primarily intended for use on the top ends of 152-mm [6-in.] diameter concrete cores, mortar specimens, or other samples of concrete of insufficient test area to permit the conduct of tests by Test Method C 418 or C 779/C 779M, this test method is also applicable on concrete surfaces in place by measuring the abrasion loss as described in Section 9, Procedure B, of Test Method C 779/C 779M.

Реферат

This test method covers the procedure for determining the abrasion resistance of either concrete or mortar surfaces using the rotating-cutter method. The method involves an abrasion device, a rotating cutter, a balance and a leveling plate. The surface description, size, and finish type of the specimen, as well as the concrete compaction, age, and strength; applied surface treatment; abrasion time; load used; depth of wear; mass loss; and abrasion time are reported. This test method has been successfully used in the quality control of highway and bridge concrete subject to traffic.

Область применения

1.1 This test method covers a procedure for determining the resistance of either concrete or mortar to abrasion. This test method is similar to Procedure B of Test Method C 779/C 779M.

1.2 The values stated in SI units or inchpound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

1.3 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.
