Power Gel Microsilica Z1
Mechanism of Action
-
Silica Fume:
The silica fume used in Power Gel Microsilica Z1 acts as a pozzolanic material, reacting with water and calcium hydroxide to produce calcium silicate. This process increases concrete hardness and durability.
-
Polycarboxylate Ether:
Serves as a superplasticizer. It coats cement particles, preventing their agglomeration and eliminating voids between them. By imparting similar electrical charges to the particles, it creates repulsive forces that improve concrete flowability.
-
Polypropylene Fibers:
These fibers enhance the mechanical properties and abrasion resistance of the concrete.
Overall, these components combine to improve the hardness, durability, workability, and wear resistance of concrete.
Properties and Effects
- Produces high‑strength concrete at both early and final curing stages.
- Densifies the concrete structure, blocking penetration of harmful ions.
- Increases structural durability by reducing cracking and environmental damage.
- Improves pumpability, reduces segregation, and makes concrete placement easier.
- Prevents surface cracks by controlling undesirable reactions and refining microstructure.
- Free from harmful chloride ions, making it suitable for corrosion‑sensitive reinforced structures.
- Enhances resistance to freeze–thaw cycles.
- Provides all key mechanical and durability benefits without the need for multiple other additives.
Applications
- High‑performance and ultra‑high‑performance concrete (HPC, UHPC).
- Major civil projects: bridges, dams, tunnels.
- Structures exposed to chemical attack (e.g., water and wastewater treatment plants).
- Marine or corrosive environments.
- Industrial floors, parking lots, production halls.
- Concreting in extreme cold or hot climates.
- High‑rise buildings requiring exceptional stability.
- Infrastructure projects such as metros and transport systems.
- Precast elements, beams, slabs, columns.
- Thin or heavily reinforced sections requiring easy pumping.
- Pools, water tanks, channels, and hydraulic structures.
Safety Guidelines
- Avoid direct contact with skin and eyes.
- In case of contact, rinse with plenty of water.
- Wear gloves, mask, and safety goggles.
- Use in well‑ventilated areas.
- Do not ingest or inhale.
- If swallowed or adverse symptoms occur, seek medical attention immediately.
Storage Guidelines
- Store in its original, tightly closed container.
- Keep in a dry, cool place away from direct sunlight.
- Storage temperature: 5°C to 35°C.
- Protect from freezing.
- Keep out of reach of children and animals.
- Shelf life: up to 12 months from production under proper storage conditions.
Dosage
The required quantity depends on concrete application, desired mechanical properties, environmental conditions, and water‑to‑cement ratio.
- Typical usage: 3% to 5% of cement weight per m³ of concrete.
- Example: For 400 kg cement/m³, use 12–20 kg Power Gel.
- Exact dosage should follow project requirements, lab results, and manufacturer recommendations.
- Over‑ or under‑dosing may affect workability, setting time, and final properties. Standard dosing ensures higher cohesion, durability, and reduced permeability.
Key Role in Durability and Quality
Power Gel Microsilica Z1, with its advanced blend of microsilica and chemical activators, is recognized as one of the most effective concrete sealing and performance‑enhancing additives in construction. It significantly boosts compressive strength, durability, water tightness, and crack resistance, making it ideal for demanding technical projects.
