SINTA® Microfibers

SINTA® F Fibers may be used in any application where designers, contractors or producers want decreased cracking due to plastic settlement. These microfibers help to lower permeability. In addition, SINTA® F, SINTA® M or SINTA® FDS microfibers increase concrete cohesiveness, which enables contractors to place concrete on steep inclines and in slipform without tremendous difficulty. Applications where synthetic microfibers can be used include slabs on grade, overlays, sloped walls, pools, shotcrete, stucco, tunnels, precast and prestressed products.

Use of SINTA® F Fibers reinforces a fresh concrete mixture while its tensile strength is weakest by mechanically locking into the concrete matrix. Plastic shrinkage cracking and permeability are both reduced. At the same time, SINTA™ F Fibers increase impact, abrasion, shatter and fire-spalling resistance of the concrete. Taken together, these improvements produce higher-quality and higher-durability concrete over the lifetime of a structure.

The SINTA® FDS is a fluid delivery system containing microfibers that automates their dispensation into concrete. SINTA® FDS guarantees both a measured dose of MicroFibers and a uniform dispersion throughout the concrete matrix. By treating MicroFibers like an admixture, it can be assured and documented in the batch like any other material. Automating dispensation improves productivity and safety at the ready mix plant, and in hands-on trials results in both easier concrete handling during a pour and a smoother finish.

SINTA® F Fibers and SINTA® FDS are compatible with all other our admixtures. Producers can achieve amazing strength, flexibility, and finishability by using SINTA® F Fibers products in combination with superplasticizers such as ADVA®.
