Product Description

Factory supply E type chopped glass fiber for dry wet mix molding

E Glass Fiber Depiction

E-type chopped glass fiber is used in GRC (glass fiber–reinforced concrete) because it disperses evenly in both dry and wet mixes, making molding much easier. Plus, E glass has strong strands and good flow, so it’s easy to work with — products made with it are tough and have smooth, high-quality surfaces.

E Glass Fiber Application

Here are some practical tips for incorporating chopped-strand E-glass fiber into common concrete mixes. Dosages are shown in kg/m3 and fiber lengths in mm — tweak them within the ranges to hit your goals (shrinkage control, impact resistance/toughness, or residual strength).

◆ Slab on grade (floor slabs, industrial slab)

Fiber length: 6–12 mm Dosage: 0.5–2.0 kg/m3

Use-case:

0.5–1.0 kg/m3: control plastic/shrinkage cracking and reduce microcracks.

1.0–2.0 kg/m3: improved post-crack toughness, abrasion resistance for heavy traffic.

◆ Exterior pavements & overlays (driveways, thin overlays)

Fiber length: 12–25 mm Dosage: 1.0–3.0 kg/m3

◆ Precast elements (panels, blocks, non‑structural panels)

Fiber length: 12–25 mm Dosage: 1.0–4.0 kg/m3

Use-case:

1.0–2.0 kg/m3: reduce shrinkage cracking and aid handling.

2.0–4.0 kg/m3: partial replacement of light secondary reinforcement for improved post‑crack behavior—must be

validated by testing and design codes.

◆ Shotcrete (tunnel, repair)

Fiber length: 25–50 mm Dosage: 4.0–10.0 kg/m3

◆ Fiber-reinforced thin sections (stucco, mortar, GFRC)

Fiber length: 3–12 mm Dosage: 0.5–2.5 kg/m3

Use case: reduce cracking and improve tensile/flexural toughness in thin composites.

E Glass Fiber Storage

E Glass Fiber should be stocked in dry places. The best conditions are a temperature between 15 and 35 °C and a relative humidity between 30% and 70%. Please keep the product in its original packaging before use to prevent exposure to moisture.
