This specification covers polyolefin chopped strands (fibers) for use in concrete. Tensile and tenacity properties are calculated by determining the breaking force, the breaking tenacity, and the elongation of adequately conditioned polyolefin filaments using Practice D1776. Conformance requirements for chopped strands for use in concrete include compliance with Specification C1116/C1116M, Type III as well as denier, finish content, tensile strength, and cut length.

Область применения

1.1 This specification covers polyolefin chopped strands (fibers) for use in concrete.

1.2 The values stated in either SI units or inch-pound 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 non-conformance with the standard.

1.3 The following safety hazards caveat pertains only to the test methods described in this specification: 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.
