BASF announces first-of-its-kind macrosynthetic fiber with integral chemistry for superior bonding
MasterFiber® MAC 2200 CB provides improved concrete performance, lower fiber dosage and better handling
CLEVELAND, February 3, 2015 – BASF Corporation’s Admixture Systems business today announced the introduction of MasterFiber® MAC 2200 CB, a first-of-its-kind macrosynthetic fiber that chemically bonds to concrete, providing enhanced post-crack flexural performance, as compared to typical high-performing macrosynthetic fibers. This superior performance enables lower dosages of fibers to achieve desired shrinkage and temperature cracking control.
The benefits of lower fiber dosage include greater concrete workability and easier placement, improved fiber dispersion and mix design optimization.
“Unlike a typical inert macrofiber, MasterFiber MAC 2200 CB creates a chemical bond with the concrete that allows the fiber to perform more effectively,” said Kirk DeCapite, Product Manager. “Through a breakthrough polymer resin technology and a highly engineered fiber architecture, MasterFiber MAC 2200 CB bonds to the cementitious matrices within the concrete to provide enhanced residual strength.”
MasterFiber MAC 2200 CB product was created to replace welded-wire reinforcement and No. 3 and No. 4 (10 mm and 13 mm) reinforcing bars that are typically used as temperature and shrinkage reinforcement. It is recommended for use in cast-in-place and wet precast concrete, slabs-on-ground, bridge decks, concrete pavements, and white topping and overlays.
“More and more concrete professionals are using macrofibers in place of traditional secondary reinforcement due to their ability to provide consistent reinforcement throughout the concrete matrix,” DeCapite said. “We were able to leverage BASF’s superior expertise in chemistry to create a truly unique and performance-enhancing macro fiber to make life easier for concrete producers and contractors.”
Another recent enhancement to BASF’s macrofiber portfolio is an advanced packaging system that aligns the fibers to improve their dispersion in a concrete mixture compared to traditional loose fiber packaging.
