polymeerilitteitä

Polymeerilitteitä, known in English as polymer concrete, is a composite material that uses polymers as a binder instead of traditional cement. It is created by mixing a polymer resin with aggregates, such as sand, gravel, or crushed stone, and then curing the mixture. The specific properties of polymer concrete depend on the type of polymer used, the aggregate composition, and the curing process. Common polymer binders include epoxy resins, polyesters, and methacrylates.

Polymer concrete offers several advantages over conventional concrete. It exhibits high strength, excellent resistance to chemicals and corrosion, and low permeability, making it suitable for demanding environments. Its rapid curing time can significantly reduce construction schedules. Furthermore, it can be formulated to have a wide range of properties, including high abrasion resistance, electrical insulation, and aesthetic finishes.

Applications for polymer concrete are diverse. It is used in industrial flooring, bridge decks, repair materials for concrete structures, decorative elements, and precast components. Its resistance to aggressive substances makes it valuable in chemical plants and wastewater treatment facilities. In marine environments, its durability and corrosion resistance are highly beneficial. The development of polymer concrete continues to focus on improving cost-effectiveness, sustainability, and performance characteristics for new and existing applications.
