INTRODUCTION

What is polymer concrete???Polymer concrete is a material made up of different

types of aggregates adhered by polyester resins.

This material is a lightweight in nature, and its

practically zero percentage of water absorption

guarantees complete watertightness.

Furthermore, its stability toward the freezing

-thawing cycles, its high resistance to most

chemicals and shock, and its minimum wear

from abrasion are other characteristics that

make polymer concrete a high quality

material.

TYPES OF POLYMERS

Latex base rubber polymer.

Acrylic base polymer.

SBR (styrene butadiene rubber).

Epoxy polymer.

DECORATIVE CONCRETE

Scope of work

Polymer concrete may be used for new construction or

repairing of old concrete.

The adhesion properties of polymer concrete allow

patching for both polymer and cementitious concretes.

It can also be used as a replacement for asphalt

pavement, for higher durability and higher strength.

The low permeability of polymer concrete allows it to

be used in swimming pools, sewer pipes, drainage

channels, electrolytic cells , and other structures that

contain liquids

ADVANTAGES1) Rapid curing at ambient temperatures.

High tensile, flexural, and compressive

strengths.

2) Good adhesion to most surfaces.

Good long-term durability with respect to freeze

and thaw cycles.

3) Low permeability to water and aggressive

solutions.

4) Good chemical resistance.

5) Good resistance against corrosion.

6) Lightweight.

7) May be used in regular wood and steel

formwork.

CONCLUSIONS

There is an increase in the workability of concrete

without adversely affected on strength of concrete.

There is an improvement in the strength of

concrete as the increase in strengths due to the

addition of polymer at a optimum W/C ratio.

Tensile strength increases up to 21.32 %.

Compressive Strength increases up to 37.31%
