Product Description
SINTA® FDS2219 is a fluid delivery system that contains SINTA® M2219—a synthetic micro-monofilament polypropylene fiber for concrete plastic shrinkage control. It allows automated dispensing of fibers into concrete. An accurate and recordable dosage of fibers can be delivered in an efficient and safe manner. The product is engineered specifically for rapid and uniform dispersion of fibers in concrete during batching.
Compliance and Certification
- ASTM C1116 / C1116M, Standard Specification for Fiber-Reinforced Concrete, Type III Synthetic Fiber-Reinforced Concrete
- Meets ICC ES AC32 criteria for Plastic Shrinkage Crack Reduction
Product Advantages
SINTA® FDS2219 uniformly distributes multi-dimensionally through-out the concrete mixture. The extremely high number of fibers in the fresh concrete matrix protects the concrete when its tensile strength is lowest, reducing the formation of plastic shrinkage cracking. The reinforcement reduces the formation of all types of early age cracking. This cracking caused by plastic shrinkage, settlement and other internal stresses would otherwise permanently weaken the resultant concrete. This cracking and other internal stresses would otherwise permanently weaken the resulting concrete. The concrete permeability is decreased, while surface characteristics, impact and toughness properties are improved.
When tested in accordance with ICC ES AC32 criteria for plastic shrinkage crack reduction, the SINTA® M2219 fibers contained within the SINTA® FDS2219 provided a 78% reduction in plastic shrinkage cracking over a control sample when dosed at 0.5 pcy.
Technically advanced production techniques make SINTA® FDS2219 a highly durable fiber that is virtually invisible in fresh concrete. This minimizes fiber-reinforced concrete finishing concerns while providing the highest level of crack protection available.
- Protects concrete when tensile strength is at its lowest, reducing the formation of plastic shrinkage cracking.
- Enhances impact and toughness properties.
- Easy to mix and fast to disperse.
- Minimizes fiber-reinforced concrete finishing concerns.
- Reduces plastic shrinkage cracking and improves durability.
- Protects concrete from stresses that cause cracking.
- Provides cost effective control of plastic shrinkage.
- Provides overall higher quality of concrete.
Uses
SINTA® FDS2219 fluid delivery system is used in the concrete batching plant for automated addition of fibers into concrete. The fluid delivery system is used in any application where SINTA® M2219 can be used as an alternative to light-gage welded-wire reinforcement to reduce cracking due to plastic shrinkage and improve durability.
Specifically, such applications include but are not limited to, slabs on grade, pavements, overlays, sloped walls, pools, shotcrete, stucco, precast and prestressed products. It is suggested that this product be used in conjunction with properly compacted base materials and jointing in accordance with ACI guidelines and standards.
Addition Rates
SINTA® FDS2219 fluid delivery system may be added to the mixer any time during the batching process.
The standard range of addition of SINTA® FDS2219 is 0.3 to 0.6 gal/yd3 (equivalent of 0.5 to 1.0 lbs of SINTA® M2219 per cubic yard) as shown in the table below. When tested in accordance with ICC ES AC32 criteria for plastic shrinkage crack reduction, the SINTA® M2219 fibers contained within the SINTA® FDS2219 provided a 78% reduction in plastic shrinkage cracking over a control sample when dosed at 0.5 pcy, corresponding to a SINTA® FDS dosage rate of 0.30 gpy. One gallon of SINTA® FDS2219 contains 0.8 gallons of water.

| 0.50 | 0.30 |
| 0.75 | 0.45 |
| 1.00 | 0.60 |
| 1.50 | 0.90 |
Compatibility with Other Admixtures
SINTA® FDS2219 is compatible with all admixtures. Its action in concrete is purely mechanical and will not affect the hydration process. Each admixture should be added separately.
