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 […]
Fiber-Reinforced Pervious Concrete – Increase Your Paving Business with This New Winner
May 15, 2014
Recently, the National Ready Mixed Concrete Association’s (NRMCA) Concrete INFOCUS publication discussed some opportunities and challenges in its NRMCA Services and Tools article about increased cooperation between concrete producers and contractors. According to NRMCA, each year parking lots and local roads present a paving market of more than 400 million cubic yards of concrete – a market of which […]
Fiber Reinforced Pervious Concrete Specification
May 14, 2014
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 5184.108.40.206 Opening to Traffic reads: Do not open the pavement to vehicular traffic until concrete has cured at least 7 uninterrupted days … ADDENDUM […]
The Benefits of Value Engineering: Ultra-Thin Whitetopping (UTW) Lasts Three Times Longer
November 1, 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, more specifically Fiber Reinforced Concrete (FRC), is placed on failed HMA. The Federal Highway Administration has approved UTW and actually was instrumental in its initial field research and […]
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 […]
Which Products Require Bulk Bags Made with Coated Fabric and Why?
August 12, 2013
Among the many varied characteristics of bulk bags, such as size, style and fabric, one of the most important is whether the bag is uncoated or coated. Just when and why is a coated bulk bag essential rather than an uncoated one? Bulk bags are made of “breathable” woven polypropylene. Air and water will flow through an […]
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 […]
Value Engineering Supports Fiber Reinforced Concrete
May 6, 2013
In school, engineers are trained to use three elements to solve a technical problem: Given, To Find and The Solutions. In the real world, the civil/structural engineer is faced with a number of additional parameters to consider. Another engineering concept, Value Engineering (VE), provides a technical solution linked with economic benefits that add definitive value for all project participants. Fiber Reinforced […]
Which Products Require Bulk Bags Made with Uncoated Fabric and Why?
April 26, 2013
Manufacturers and shippers use ABC Polymer bulk bags to efficiently and economically transport and store a wide variety of products. Bulk bags come in many different sizes, styles and fabrics with varied tops, bottoms, loops and other features. Various types of bulk bags are ideal for transporting and storing a wide variety of powders, granules, […]
