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 ”

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.

 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.
