SINTA® FDS2219

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.

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.
