JBS ULTRAFINE 92

Product Description

JBS ULTRAFINE 92 is a densified silica fume, an ultrafine powder co-product from the silicon or ferrosilicon industry, rich in silicon dioxide (SiO₂). It enhances concrete performance by chemically reacting with calcium hydroxide to form additional calcium silicate hydrate (C-S-H) gel and by filling voids between cement particles, resulting in denser, more durable, and impermeable concrete.

Uses

JBS ULTRAFINE 92 is ideal for:

• High Strength Concrete
• High Performance Concrete
• Ready Mix Concrete
• Precast and Cast-in-Situ Concrete
• Dry and Wet Shotcrete
• Underwater Concrete
• Self-Compacting Concrete (SCC)

Features and Benefits

• Improved Strength and Density: Achieves ultra-high compressive strength and better flexural strength.
• Reduced Permeability: Enhances water tightness and limits the ingress of water, chlorides, sulphates, and chemicals.
• Chemical Resistance: Provides resistance against chlorides, sulphates, acids, and other aggressive chemicals.
• Corrosion Protection: Minimizes reinforcement corrosion.
• Durability: Offers excellent freeze/thaw, abrasion, and erosion resistance.
• Prevents Bleeding and Segregation: Ensures consistent concrete mix quality.
• Structural Efficiency: Reduces member size and increases span lengths for improved structural economics.

Applications

• Basement structures, parking decks, and bridge decks.
• Marine and underwater structures.
• High-performance and prestressed concrete applications.
• Concrete with low cement content or requiring impermeability and chemical resistance.

Advantages

• Enhances durability and compressive strength.
• Ideal for challenging environments requiring high chemical and corrosion resistance.
• Reduces accelerator dosage for shotcrete applications.
• Provides design flexibility and improved structural economics.
