3. Polymer concrete(PC)
Polymer concrete is a versatile, durable, composite material produced by
mixing a variety of mineral fillers with a synthetic or natural resin binding
agent.
It is also known as “ Resin Concrete ”
4.
5. latex-modified concrete (LMC): also known as polymer Portland
cement concrete. Conventional concrete made by replacing part of
mixing water with a latex.
Polymer-impregnated concrete (PIC):produced by impregnating or
infiltrating a hardened concrete with a monomer and subsequently
polymerizing the monomer in situ.
Polymer concrete (PC): formed by polymerizing a mixture of a
monomer and aggregate (no other bonding material)
Types of PC:
6. • Depending on the materials employed, PC can develop compressive
strengths of the order of 140 MPa (20,000 psi) within hours or even
minutes .
• LMC possess excellent bonding ability to old concrete, and high
durability to aggressive solutions; it has therefore been used mainly for
overlays in industrial floors, and for rehabilitation of deteriorated bridge
decks.
• In the case of PIC, by effectively sealing the micro cracks and capillary
pores.
Significance
7. • Commercial products are available with a variety of
formulations, some capable of hardening to 105 MPa(15,000
psi) within a few minutes without thermal treatment.
• Epoxy resins are higher in cost but offer advantages such as
adhesion to wet surfaces.
• Styrene monomer, and methyl methacrylate (MMA) with
benzoyl peroxide catalyst and an amine promoter are often
used.
Properties of PC:
12. Material Features:
High resistance to chemical and biological attack
Lightweight compared to cement concrete products
Excellent noise and vibration absorption
Excellent dielectric properties
Good weathering and UV resistance
Zero water absorption
Can be cut with masonry drills and grinders
Can be recycled as rubble or crushed for use as road foundation
Approximately 4 times the flexural strength of cement concrete
Good thermal properties and stability
Ultra smooth finish which encourages efficient hydraulic flow

14. Applications:
• Used for pump bases, flooring blocks, chemical containment,
trench drains and more.
• Solid surface countertops for modern kitchens and baths.
• With its decorative finishes and excellent resilience, polymer
concrete is ideal for many ornamental applications including park
benches, outdoor furniture, and waste containers.
• Commonly used in areas subject to heavy wear and high
loadings such as car parks, roadways and industrial areas.
