Construction Chemical In Bhopal
Details of Construction Chemical
Construction chemicals are specialized chemical formulations used in the construction industry to enhance the performance, workability, longevity, and sustainability of construction materials. They play a critical role in modern construction practices, including buildings, infrastructure, and industrial projects.
Main Categories of Construction Chemicals
Concrete Admixtures
Purpose: Modify and improve the properties of fresh or hardened concrete.
Types:
Plasticizers/Superplasticizers: Increase workability without extra water.
Accelerators: Speed up setting time (e.g., calcium chloride).
Retarders: Slow down setting time in hot weather.
Air-entraining agents: Introduce micro-air bubbles to improve freeze-thaw resistance.
Water-reducing agents: Reduce water content while maintaining workability.
Waterproofing Chemicals
Purpose: Prevent water penetration and dampness.
Types:
Cementitious waterproofing: Applied on internal wet areas like bathrooms.
Bituminous coatings/membranes: Used on foundations and roofs.
Polyurethane or acrylic-based membranes: Flexible and UV resistant.
Crystalline waterproofing: Penetrates concrete and blocks water paths via crystal growth.
Grouts and Anchors
Purpose: Fill gaps, cracks, or anchor structures.
Types:
Cementitious grouts: For general crack and void filling.
Epoxy grouts: Chemical resistant and high strength for industrial use.
Polyester/chemical anchors: Used to fix bolts or rods in concrete.
Repair and Rehabilitation Products
Purpose: Restore and protect damaged structures.
Examples:
Polymer-modified mortars: For patching and surface repairs.
Epoxy mortars/resins: High bond strength for structural repair.
Rust removers and corrosion inhibitors: For reinforcing steel protection.
Sealants
Purpose: Seal joints and gaps against moisture, air, and other elements.
Types:
Silicone-based: For expansion joints in buildings.
Polyurethane-based: For movement joints in concrete.
Acrylic-based: For lower-movement applications.
Flooring Compounds
Purpose: Prepare, level, and protect industrial and commercial floors.
Examples:
Self-leveling compounds
Eoxy and polyurethane floor coatings
Anti-static coatings for electronic industries
Curing Compounds
