Apr 29,2014·It is important to remember the classification in ASTM A820 covers fibers,while the classification in ASTM C1116 covers concrete mixes.Fiber length The steel fibers used in concrete floors range in length from 25 to 65 mm (1 to 2 1/2 in.).While it is usually agreed length matters,there is no consensus as to which length is best.

Concrete Reinforcing Fibers - Sikasp.infoThe main standards for fiber reinforced concrete are ASTM C 116 and EN14889.ASTM C 116,Standard Specification for Fiber Reinforced Concrete,outlines four (4) classifications for fiber reinforced concrete Type I - Steel fiber-reinforced concrete or shotcrete (ASTM A820) Type II - Glass fiber-reinforced concrete or shotcrete (ASTM C1666)ASTM A820 Standard Specification for Steel Fibers for
