Microcast 200

PDFPrint
MICRO-CAST 200 fibers are very small diameter, fibrillated fibers manufactured from 100% virgin polypropylene resin and exceed the requirements of ASTM C 1116 “Standard Specification for Fiber-Reinforced Concrete and Shotcrete”, Type III Synthetic Fiber-Reinforced Concrete. They are specifically engineered for use in concrete as secondary reinforcement and controlling plastic shrinkage and settlement cracking. MICRO-CAST 200 fibrillated fibers are extremely small diameter that makes them perfect for precast, stucco, shotcrete, and architec- tural concrete. MICRO-CAST 200 fibers are manufactured to the requirements of the International Building Codes. MICRO-CAST 200 fibers are designed for early crack-control but they also do an excellent job of increasing the impact, shatter, and abrasion resistance of the concrete.

Description

 

MICRO-CAST 200

 

FIBRILLATED MICRO-SYNTHETIC

Guidelines

MICRO-CAST 200 fibers are specifically engineered for use in concrete as secondary reinforcement, and for the purpose of controlling plastic shrinkage and settlement cracking. The minimum dosage rate for MICRO-CAST 200 fibers is 1.5 lbs. per cubic yard of concrete, unless otherwise specified. We recommend following ACI guidelines for control joint locations and details. Please consult DE Fiberworks for dosage rates for your application, design information, or more details when using MICRO-CAST 200 fibers..

 

Applications

 

MICRO-CAST 200 fibers may be used in all types of concrete and are ideal for the following applications:

Precast

Decorative Concrete

Architectural Concrete

Stucco

Non-magnetic applications

Mixing, Placing & Finishing

 

Mixing – MICRO-CAST 200 fibers are packaged in pre-measured water soluble bags designed to be introduced into the concrete mix before, during, or after batching other concrete materials. Care should be taken to make sure the fibers are not added to the tail end of a high slump mix. Mixing should conform to ASTM C 94 with a minimum of 75 revolutions of the drum at full mixing speed to ensure uniform distribution of the fibers.

 

Reinforcement Objective

 

To inhibit plastic and settlement shrinkage cracking prior to the initial set, and to reduce hardened concrete shrinkage cracking, improve impact and abrasion resistance, and enhance concrete toughness and durability. Provide entry level reinforcement used for shrinkage & temperature reinforcement.

Placing – MICRO-CAST 200 fibers can be pumped and placed using conventional equipment.

Finishing -Standard finishing equipment and techniques can be used when working with MICRO-CAST 200 fibers.

Fiber reinforcement makes good concrete better?

 

Fiber reinforcement makes good concrete better, in short because fiber reduces cracking and adds long-term durability to a wide variety of concrete applications.  Fiber reinforcement provides an alternative construction method to traditional welded wire fabric and rebar reinforcement and provides additional benefits, including guaranteed 3-dimensional reinforcement, safer installation and more economical.  DE Fiberworks supply a full range of fiber reinforcement products to meet challenging demands and provide the best fiber reinforcement solution for the specific application.   Fiber technology has advanced over the last decade to improve mixing, finishing and performance in fresh and hardened concrete.
