Polymer concrete, also known as polyconcrete, is a composite material that consists of aggregates bound together with a polymer resin instead of Portland cement.

Beyond Cement: Exploring the Superiority of Polymer Concrete

Polymer concrete has emerged as a versatile construction material that promises to transform the building industry. With its unique properties, polymer concrete addresses many limitations of conventional concrete. This new material heralds a new era of sustainable and durable infrastructure development.

What is Polymer Concrete?

The polymer resin used can be epoxy, vinyl ester or latex and provides properties that are superior to conventional concrete. By combining aggregates with polymer resins, polymer concrete gains the durability and strength of concrete along with flexibility, corrosion resistance and waterproofing of polymers.

Different Types of Polymer Concrete

There are various types of polymer concrete available in the market based on the polymer resin used:

Epoxy Polymer Concrete: Epoxy resin is the most commonly used binding agent for polymer concrete. It provides high compressive and flexural strength along with excellent adhesion and chemical resistance. Epoxy polymer concrete is ideal for applications where corrosion resistance is critical.

Vinyl Ester Polymer Concrete: Vinyl ester resin is similar to epoxy but has better resistance to thermal cycling. It is suitable for environments with extreme temperature fluctuations.

Polyester Polymer Concrete: Polyester resin based concrete has good mechanical properties and is more economical compared to epoxy. It finds use in industrial flooring and containment structures.

Latexacrylic Polymer Concrete: Using latex or acrylic emulsion as binder results in concrete with outstanding flexibility and impact resistance. It is preferred for overlay applications on existing concrete substrates.

Unmatched Durability of Polymer Concrete

One of the key advantages of polymer concrete is its incredible durability even under harsh environmental conditions:

- Resistance to Chemicals: Polymer concrete does not deteriorate when exposed to industrial and agricultural chemicals, de-icing salts, acids, alkalis that can damage ordinary concrete.

- Impermeability: Polymer resins make the concrete dense and impermeable to liquids and gases. It prevents corrosion of reinforcement.

-Freeze-Thaw resistance: Polymer concrete withstands repetitive freezing and thawing without cracking or degradation. It retains over 95% of its original strength even after hundreds of cycles.

- Abrasion Resistance: The polymer matrix protects aggregate particles from wearing away. Polymer concrete has 50 times higher abrasion resistance than conventional concrete.

-Long Lifespan: With proper maintenance, the lifespan of polymer concrete structures can exceed 50-100 years, reducing need for repair and replacement.

Varied Applications of Polymer Concrete

Due to its unique combination of properties, Polymer Concrete finds diverse applications across sectors:

Containments: Commonly used in waste water treatment plants, sewage works for lining tanks, channels handling corrosive/toxic materials.

Industrial Flooring: Suitable for areas with heavy vehicular traffic, chemical spillage. Used in manufacturing plants, warehouses, hangars etc.

Prestressed Components: Used to manufacture poles, pipes, tanks, manholes requiring high strength. Offers dimensional stability.

Repair and Overlays: Can be applied as thin overlay or topping on old concrete surfaces to refurbish and protect them.

Precast Products: Manufacture of precast products like utility vaults, utility boxes with impacted strength and shape retention.

Other Uses: Pavements, polymer-modified overlays, bridge decks, hydraulic structures, seawalls, marine applications.

Sustainable and Eco-friendly Material

Polymer concrete scores high on sustainability too:

- Uses locally available aggregates and requires less cement. Helps reduce cement carbon footprint.

- Durability means longer lifespan and less frequent repairs/replacements reducing carbon impact over time.

- Impervious nature prevents leaching of chemicals into soil and seepage losses.

- Can be easily recycled at end-of-life by removing polymer binder for future use as base material.

Thus, polymer concrete offers a viable alternative to conventional construction materials. With unmatched properties and sustainability, it is set to revolutionize infrastructure projects globally and help build resilient communities. Polymer concrete truly represents the concrete of the future.
