ASTM C1116 – Standard Specification for Fiber-Reinforced Concrete
This specification covers all forms of fiber-reinforced concrete that are delivered to a purchaser with the ingredients uniformly mixed. This specification may also apply to fiber-reinforced concrete intended for shotcreting by the dry-mix process when sampling and testing is possible at the point of placement. It, however, does not cover the placement, consolidation, curing, or protection of the fiber-reinforced concrete after delivery to the purchaser. Materials are classified according to the type of fiber incorporated, which are: Type I, steel fiber-reinforced concrete that contains stainless, alloy, or carbon steel fibers; Type II, glass fiber-reinforced concrete that contains alkali-resistant glass fibers; Type III, synthetic fiber-reinforced concrete that contains synthetic fibers; and Type IV, natural fiber-reinforced concrete that contains cellulose fibers. The fiber-reinforced concretes shall be furnish either by batch mixing or continuous mixing, and shall be free of fiber balls when delivered to the point designated by the purchaser. Tolerances, acceptance criteria, and performance requirements for workability and air content are discussed thoroughly.
1.1 This specification covers most forms of fiber-reinforced concrete manufactured in accordance with Specification C94/C94M or Specification C685/C685M as modified herein. It does not cover the placement, consolidation, curing, or protection of the fiber-reinforced concrete after delivery to the purchaser.
1.2 Certain sections of this specification are also applicable to fiber-reinforced concrete intended for shotcreting by the dry-mix or to zero-slump, and fiber-reinforced concrete used to manufacture precast elements. In these cases, the sections dealing with batching plant, mixing equipment, mixing and delivery, and measurement of workability and air content, are not applicable.
1.3 This specification does not cover thin-section glass fiber-reinforced concrete manufactured by the spray-up process that is under the jurisdiction of ASTM Subcommittee C27.40.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.5 If required results obtained from another standard are not reported in the same system of units as used by this standard, it is permitted to convert those results using the conversion factors found in the SI Quick Reference Guide.
