1、Designation: C 1666/C 1666M 07Standard Specification forAlkali Resistant (AR) Glass Fiber for GFRC and Fiber-Reinforced Concrete and Cement1This standard is issued under the fixed designation C 1666/C 1666M; the number immediately following the designation indicates theyear of original adoption or,

2、in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers minimum requirements foralkali resistant (AR) glass fi

3、bers intended for use in glassfiber-reinforced concrete (GFRC) by spray-up, glass fiber-reinforced concrete premix, fiber-reinforced concrete, andother cementitious based products.1.2 This specification provides for AR glass fiber types andconfigurations that can be readily incorporated into concret

4、emixes, typical physical properties, minimum zirconia content,and prescribes testing procedures to establish conformance tothese requirements.1.3 This specification does not address the types of coatingsor lubricants used in the manufacturing process of the fibers.1.4 In the case of conflict between

5、 a more stringent require-ment of a product specification and a requirement of thisspecification, the product specification shall prevail. In the caseof a conflict between a requirement of the product specificationor a requirement of this specification and a more stringentrequirement of the purchase

6、 order, the purchase order shallprevail. The purchase order requirements shall not take prece-dence if they, in any way, violate the requirements of theproduct specification or this specification; for example, by thewaiving of a test requirement or by making a test requirementless stringent.1.5 The

7、values stated in either SI units or inch-pound unitsare to be regarded separately as standard. Within the text, theinch-pound units are shown in brackets. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues fro
