Polymer Concrete

Over time, conventional reinforced concrete can degrade and corrode due to environmental exposure, which requires costly and disruptive maintenance to repair. Composites not only offer better corrosion resistance than conventional concrete, they can weigh up to 75 percent less while providing comparable or much improved tension and compression strength.

Advantic offers a range of proprietary polymer concrete formulations, so our engineers can design to your specific performance requirements and budget constraints. Our lightest formulations allow us to pre-assemble large sections that can be lifted by crews without expensive and dangerous overhead equipment.  Heavier formulations tend to be more economical. They are a great alternative for underground utility vaults and trenches, as they are not susceptible to corrosion and have no permeability issues.

Process

Continuous or batch mix

Filler (analogous to aggregate) is mixed with polymeric resin (analogous to cement paste) and agitated in a form or mold.

Benefits

The strength of high-performing concrete at up to 75% less weight

Formulation can be tailored to meet cost-performance tradeoff goals.

Conventional, unreinforced cement concrete Advantic polymer concrete Performance comparison of polymer concrete to conventional concrete
Density (lb/ft3) 110 to 150 35 to 150 Up to 75% lighter
Unconfined compressive strength (lb/in2) 500 to >15,000 500 to >17,000 Equally as strong as high-performance and ultra-high-performance conventional concrete
Tensile strength (lb/in2 400 2,000 to 4,500 Up to 11 times greater strength
Flexural strength (lb/in2) 480 3,000 to 5,500  
Modulus of elasticity (lb/in2) 3.650 x 106 .15 to 5.6 x 106 Less stiff with better impact response
Will not leach into environment or crack and wear like coated/treated steel, concrete and wood

Resistant to a broad range of chemical and aqueous environments that cause rust and rot
Inherently RF permeable.
Thermally insulated formulations provide conductivity of 0.089 W/m-K (equivalent to R-1.62 per inch).

Electrically insulated formulations provide:
• Dielectric constant ASTM D150-65T 2.38
• Dielectric strength ASTM D149 >500 KV/in
• Operating temperatures -45 °C to 200 °C
• UL94 flammability V-0
Conventional formulations achieve ASTM E84 Class A fire rating with:
• Flame Spread Index <25
• Smoke Developed Index <450

Product Forms

  • Panels and blocks
  • Trench drains and underground enclosures
  • Column or pile remediation jackets
  • Electrical insulators
  • Thermal insulators
  • Blast and ballistic panels
  • Structural linings for abrasive/erosive environments

The Bottom Line

Polymer concrete is ideal for cast structural elements where:

  • Installed weight affects installation speed
  • Parasitic load is detrimental to existing structures and foundations
  • Corrosion affects conventional reinforced concrete
  • RF permeability is critical
  • Low thermal or electrical conductivity is paramount

With the same strength as high-performing concrete at significantly less weight, polymer concrete allows you to reduce the supporting infrastructure. It also comes in multiple formulations, allowing you to balance performance needs with total cost goals.
