Description
SINTA® M2219 is a synthetic fiber for concrete, manufactured from 100% virgin polypropylene in a micro-monofilament form. SINTA® M2219 is produced on a state-of-the-art production line which is specifically designed to yield an ultrathin concrete reinforcing fiber able to achieve superior performance at a lower dosage rate compared to conventional monofilament fibers. SINTA® M2219 contains over 70 million individual fibers for each 1.0 lb/yd3 dosed. Engineered specifically for use in concrete, they are alkali resistant, non-absorptive and completely non-corrosive. SINTA® M2219 protects concrete from stresses which cause cracking while the concrete is most vulnerable during the first 24 hours after placement. SINTA® M2219 complies with ASTM Designation C1116, Standard Specification for Fiber-Reinforced Concrete and Shotcrete, Type III Synthetic Fiber-Reinforced Concrete or Shotcrete. SINTA® M2219 is available in 19 mm (0.75 in.) length.
SINTA® M2219 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, SINTA® M2219 fibers provided a 78% reduction in plastic shrinkage cracking over a control sample when dosed at 0.5 pcy.
Technically advanced production techniques make SINTA® M2219 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.
