In Peru, where seismic activity and diverse climatic conditions pose significant challenges to infrastructure, the durability of concrete is a primary concern for engineers and
contractors. Standard concrete often suffers from shrinkage cracks and reduced structural integrity over time. To address these issues, professional builders are increasingly turning to high-performance fiber reinforcement to enhance the tensile strength and impact resistance of their cementitious materials.
Recently, a prominent construction group in Peru collaborated with YUNIU to upgrade their concrete mix design for a series of industrial flooring and residential foundation projects.
The client needed a solution that could be easily dispersed in the concrete mix without clumping, providing uniform 3D reinforcement. After rigorous testing for workability and post-crack strength, the client selected our 12mm E-Glass Chopped Strands, specifically designed for cement and mortar reinforcement.
To meet the specific requirements of the Peruvian construction standard, the following technical specifications were provided:
Product Type: E-Glass / Alkali-Resistant (AR) Fiberglass Chopped Strands
Chop Length: 12mm
Filament Diameter: 13μm
Sizing Type: Silane (High compatibility with cementitious binders)
Moisture Content: ≤ 0.10%
Loss on Ignition (LOI): 0.40% - 0.80%
Packaging: 25kg Kraft paper bags / Jumbo bags for industrial use
The 12mm length is the "golden standard" for preventing micro-cracks in concrete and mortar. Unlike shorter fibers, the 12mm strands provide sufficient anchorage within the cement matrix to effectively bridge cracks during the early stages of drying and curing.
Furthermore, our fibers feature a specialized sizing agent that ensures excellent dispersion. This means every cubic meter of concrete is reinforced with millions of individual glass filaments, creating a high-strength internal support network that significantly reduces water permeability and increases freeze-thaw resistance.
With over 24 years of expertise in fiberglass manufacturing, YUNIU has become a preferred supplier for the South American market. We understand the logistical complexities of shipping to ports like Callao and Paita and provide the documentation needed for smooth customs entry.
Integrated Quality Control: We monitor everything from glass furnace temperatures to the precision of the chopping process.
South American Market Expertise: We offer tailored packaging and labeling to meet local Peruvian regulatory requirements.
Capacity & Stability: Our large-scale production ensures that even for infrastructure projects requiring hundreds of tons, we maintain stable lead times and consistent quality.
For construction professionals in Peru, 12mm fiberglass chopped strands offer a cost-effective, high-performance alternative to traditional steel mesh reinforcement. By choosing YUNIU’s precision-engineered fibers, you are investing in the long-term safety and durability of your structures.
