This document compares polymer concrete to normal concrete. Polymer concrete contains aggregates bonded together with polyester resins, making it lightweight and highly resistant to water absorption, freezing/thawing cycles, chemicals, and abrasion. It has higher compressive and tensile strengths than normal concrete, with compressive strength increasing up to 37% and tensile strength up to 21%. A case study examines how polymer concrete was used to repair basement coat failures at a hotel in Singapore. The document concludes polymer concrete has improved workability and strength properties over normal concrete.

2. 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.

3. 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.

4. TYPES OF POLYMERS
 Latex base rubber polymer.
 Acrylic base polymer.
 SBR (styrene butadiene rubber).
 Epoxy polymer.

5. DECORATIVE CONCRETE

8. 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

9. ADVANTAGES
1) 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.
8) DECORATIVE CONCRETE

15. 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%
