Polymer Concrete is a composite made of aggregates (similar to those used in a conventional Portland Cement Concrete) and Unsaturated Polyester Resin – UPR.
No Cement nor Water are used in the manufacturing of Polymer Concrete.
The resin once cured, binds the aggregates together. Giving Polymer Concrete a strength three times greater than conventional Portland Concrete.
Polymer Concrete has been around for over fifty years in one form or another.
Polymer Concrete can be cast into shape, making it ideal for producing prefabricated structures normally produced in Reinforced Concrete particularly where the high strength of Polymer Concrete can be used in the design resulting in much thinner wall sections.
Manufacturing using Polymer Concrete is far more complex than conventional Reinforced Concrete. The resin used is both flammable and toxic as the curing of this resin depends on an organic chemical reaction. The selection of both the base resin and the curing agents is critical.
As the percentage of resin is kept below 15% by weight of the Polymer Concrete the selection and design of the moulds or formwork used is critical. None of the resin, powders or fine sand can be allowed to leak out.
Polymer Concrete cures within two hours and can be extracted at this time. Depending on the ambient temperature, it may be necessary to post cure the finished Polymer Concrete to reach ultimate strength.
Once cured, Polymer Concrete is very strong and is highly corrosion resistant.
