Placing, Finishing & Jointing Tips for Fiber Reinforced Concrete
August 10, 2017
PLACING: Synthetic, steel and blended fiber reinforced concrete can be placed using conventional methods such as concrete chutes, buckets, conveyors and pumps. Whereas, fiber reinforced shotcrete can be placed using standard shotcrete equipment. WORKABILITY: The slump of concrete is NOT an indicator of workability. Slump is used to measure the consistency of the concrete from load […]
A Fiber-reinforced Concrete Testing Primer for Ready Mixers (Part 1)
March 18, 2015
In this and the next issue of Ready Mixer News Memo we will provide a general primer for ready mixers as well as engineers, contractors and commercial laboratory personnel. Part 1 in this issue includes: Sampling of Fiber Reinforced Concrete (FRC)/Fiber Reinforced Shotcrete (FRS) Fabrication of FRC/FRS test specimens. Part 2 in the next issue will cover: […]
What Are the Differences Between Types A, B, C and D FIBC Fabrics?
December 10, 2014
Bulk bag fabric types are all about controlling static electricity, which is an imbalance of electric charges within or on the surface of a material. When bulk bags are rapidly filled and discharged, the flowing movement of finely powdered substances can cause a buildup of static electricity. Removing or preventing an electrical charge is critical […]
How Should Concrete Mixes with High Dosages of Macrosynthetic Fibers Be Adjusted?
December 10, 2014
In this article we will review an acceptable approach to adjusting mix designs when ABC Polymer’s macrosynthetic fibers, FiberForce 650™ (Tuf-Max DOT™), Performance Plus DOT™ and Macro-Pro™, are used as reinforcement in the concrete at dosage levels from 3.0 to 11.0 pcy. The Basics When we talk about a standard concrete mix design there are four principal […]
Increase Project Profitability/Reduce Project Costs
October 24, 2014
Macrosynthetic Fibers Save Owners Money Over Conventional Temperature-Shrinkage Control When using conventional WWF (Welded Wire Fabric) or #3 & #4 rebar for temperature-shrinkage control Structural Engineers sometimes use a one-size-fits-all approach on projects to minimize the potential for the field crew to place the wrong reinforcement system in a cross-section. However, the Structural Engineer may […]
Seven Reasons to Use Bulk Bags Rather Than Drums or Boxes
October 6, 2014
Many cost, convenience and safety factors must be considered when determining the best type container for storing, shipping and protecting your company’s valuable product(s). Drums/barrels do not collapse when empty. Drums take up as much space when shipped to your warehouse and when stored before fill as when they are full. The average unit cost of […]
Macrosynthetic Fibers Save Owners Money Over Conventional Temperature-Shrinkage Steel Reinforcement
July 21, 2014
When using conventional temperature-shrinkage steel reinforcement the Structural Engineer tends to use a one-size-fits-all approach on projects to offset the potential for the field crew to place the wrong reinforcement system in a cross-section. Too often the Structural Engineer determines what temperature-shrinkage reinforcement is needed for the most demanding concrete application and then specifies that […]
Three-Part Master Specification: Macrosynthetic-Fiber Reinforced Concrete
July 20, 2014
This specification is specific to the use of Macrosynthetic Fibers as secondary/temperature-shrinkage reinforcement and post-first crack reinforcement in concrete. The purpose of this document is to assist design professionals in the preparation of project or office master specifications. It follows guidelines established by the Construction Specifications Institute and, therefore, may be used with minor editing […]
Ultra-Thin Whitetopping (UTW) Lasts Three Times Longer than HMA!
August 27, 2013
Ultra-Thin Whitetopping or UTW is a reversal of normal highway maintenance practice. Instead of Hot Mixed Asphalt (HMA) being placed on top of failed concrete, concrete is placed on failed HMA, more specifically, Fiber Reinforced Concrete (FRC). The Federal Highway Administration has approved UTW and has participated in a number of demonstration projects sponsored by […]
Is Fiber Reinforced Concrete Approved and Specified by Government Agencies and Engineers?
May 28, 2013
The synthetic fiber reinforcement approved for use as temperature-shrinkage reinforcement in concrete is described in ASTM C1116, Section 4.1.3 and Note 2. The chemical base of the synthetic fiber resins that are compatible with a cement concrete are listed. International Code Council (ICC) has adopted a performance-based specification for Fiber Reinforced Concrete (FRC) as either […]
