Macrofibras sintéticas: reforço estrutural para pisos industriais de concreto
Entenda como as macrofibras sintéticas contribuem para o controle de fissuras, a durabilidade e o desempenho de pisos industriais de concreto.
FG Fibras
High Performance Engineering in Fibers and Concrete Floors
Replace steel meshes, control plastic shrinkage cracks, and maximize structural durability with FG Fibras synthetic macrofibers and admixtures.
Integrated Solutions for Concrete & Industrial Floors
Combining advanced fibers and admixtures to improve concrete performance.
Structural Macrofibers
Three-dimensional continuous reinforcement, post-crack energy absorption, and direct replacement for steel welded wire mesh.
Anti-Shrinkage Microfibers
Millions of monofilaments per cubic meter blocking plastic shrinkage cracks during early concrete hydration.
Admixtures and Sealants
Polycarboxylate superplasticizers for water reduction and high-modulus polyurethane sealants for industrial floor joints.
Product Catalog
Structural fibers and chemical solutions compliant with ASTM and international standards.
aditivosABNT / ASTM
Shrinkage Compensator – FG Compensator
Solid, alkaline admixture composed of Calcium Carbonate, Magnesium Carbonate, and Calcium Oxide. High technology that compensates shrinkage, waterproofs, reduces hydration temperature, reduces cracks and microcracks, assists in expansion joints, and increases strength in cement-based mortars.
aditivosABNT / ASTM
Chemical Curing Agent - FG CURE
Formulated for fresh cementitious surfaces, creating a low-permeability film that prevents water evaporation and minimizes drying shrinkage cracking.
aditivosABNT / ASTM
Surface Hardener – FG Formula
Engineered for concrete floors, acting as a crystallization agent that seals pores in concrete and mortar, increasing waterproofing, abrasion resistance, and dustproofing with a subtle sheen.
