Our first article (Ready Mixer News Memo Feb./Mar. 2015 issue) in this important series explained the Fiber-reinforced Concrete (FRC) sampling procedure, including some of the most critical points of test specimen fabrication. This issue’s article continues the series with details of the proper testing process, along with a review of approved fibers from the ABC Polymer stable […]

Which method is best when writing specifications for fiber-reinforced concrete? This article provides the historical, testing and physical property related data — plus more — that leads to the reasoning behind ABC Polymer’s preferred method of writing fiber reinforced concrete specifications. Fiber Reinforced Concrete History — Micro Beginnings Synthetic Fibers as reinforcement for concrete were […]

In this and the next issue of Ready Mixer News Memo, we will provide a Fiber Reinforced Concrete Test Primer for ready mix professionals, engineers, contractors, and commercial laboratory personnel. Part 1 in this issue includes: A sampling of Fiber Reinforced Concrete (FRC)/Fiber Reinforced Shotcrete (FRS) Fabrication of FRC/FRS test specimens. Part 2 in the next […]

This Addendum is to be used in conjunction with ACI 522.1 Specification for Pervious Concrete Pavement ACI 522.2.23 Fibers reads: The use of fibers in pervious concrete is permitted when approved by the Architect/Engineer. Important: ACI 522.3.13.1 Opening to Traffic reads: Do not open the pavement to vehicular traffic until the concrete has cured at least 7 uninterrupted days … […]

As the use of Macrosynthetic Fibers and Macrosynthetic Fiber-Microsynthetic Fiber Blends grows, a more precise understanding of the properties of concrete reinforced with these materials is required. Currently, there are three tests on the books at ASTM that are specific to the testing of fiber reinforced concrete (FRC) post-first crack. These tests methods are C1399, […]

Let’s Talk about defining industry terms and a little about Fiber Reinforced Concrete (FRC) testing. There are some terms being used when we are defining synthetic and/or steel fibers as well as their properties and applications that create some confusion for those that may be considering using FRC. One of the terms that seem to […]
