Polymer Concrete - A durable and highly resistant construction material

Comments ยท 1 Views

Polyester concrete is a composite material that is different from conventional Portland cement concrete. It consists of aggregate (sand and gravel), resin monomer and hardener. The polymer component acts as the binding agent and replaces the Portland cement used in normal concrete. Polyest

Advantages of Polymer Concrete
The main advantages of using polyester concrete are:

Superior Strength and Durability
Polyester concrete has a tensile strength 2-5 times greater than Portland cement concrete. Its compressive strength is around 10 times more than ordinary concrete. Due to the polymer matrix, it can withstand severe environmental conditions such as wet/dry cycling, freeze/thaw action, deicing salts, chemicals and is highly durable.

Rapid Setting and Early Strength Gain
Polymer Concrete
develops working strength in 1-3 hours compared to days for normal concrete. This allows quick restart of operations where it is used. It achieves 80-90% of its designed strength within 24 hours of placement.

Superior Abrasion and Impact Resistance
The polymeric matrix makes it 50-1000 times more abrasion resistant than cement concrete. It is highly impact resistant and rarely cracks or fractures. This makes it suitable for applications requiring long lasting wearing surfaces.

Reduced Permeability
Polyester concrete is virtually impermeable as the resin fills all voids and pores. Water, chloride ions, chemicals or dirt cannot penetrate it, ensuring corrosion protection of embedded metal. This gives it an extremely long service life.

Wide Service Temperature Range
Its service temperature range is from -50°C to 120°C depending on resin type used. This is much wider than cement concrete which limits its applications.

Shrinkage Resistance
Polyester concrete undergoes very little shrinkage during curing and long term use, unlike cement concrete. This prevents cracking and improves dimensional stability.
