SINTA FDS2219 is a fluid delivery system that contains SINTA M2219—a synthetic 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.
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 are used to reduce cracking due to plastic shrinkage and improve durability.
Specifically, applications include but are not limited to, slab on grade, elevated slabs, pavements, overlays, sloped walls, pools, shotcrete, stucco, precast and prestressed concrete products.
SINTA FDS2219 fluid delivery system offers an easy, efficient and safe process for batching a measured dose of SINTA M2219. It allows uniform multi-dimensional dispersion throughout the concrete matrix. The dosage into concrete is assured and can be documented on the batch ticket just like other admixtures. Since the product batching in concrete is automated through a GCP dispenser system, it presents an opportunity for improving productivity and safety at a ready mix plant.
Additionally, in several tests conducted with SINTA FDS2219 fluid delivery system, contractors have experienced flexibility in handling concrete during the pour, and an easier and smoother finish.
- Automated dispensing of fiber reinforcement into concrete
- Assured fiber dosage
- Batch ticket confirmation
- Process efficiency improvement
- Improved productivity
- Same quality as MicroFiber
Mixing Requirements and 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 0.9 gal/yd3 (equivalent of 0.5 to 1.5 lbs of SINTA M2219 per cubic yard) as shown in the accompanying “Addition Rates” table. One gallon of SINTA FDS2219 contains 0.8 gallons of water.
Compatibility with Other Admixtures
SINTA FDS2219 fluid delivery system is compatible with all admixtures. Each admixture should be added separately to the concrete mix.
U.S. Patent No. 6,569,233
Packaging and Dispensing
SINTA FDS2219 fluid delivery system is available in totes and is added directly to the mixer during batching using a SINTA FDS2219 Dispensing System.
SINTA FDS2219 fluid delivery system will freeze and must be kept at temperatures above 40°F (4°C). If freezing does occur, allow product to completely thaw prior to using.
Do not use mechanical agitation.
