polymerized monomer acts as binder for the aggregates and the resulting composite is called Concrete. Addition of various types of fibers like glass fibers, steel fibers, and carbon fibers in polymer concrete enhances its mechanical properties such as toughness, compressive strength, flexural strength, and fatigue strength. Normally, the binder content ranges from 5 to 15 of the total weight but if the aggregate mix is fine, it may even require up to 20 binder. The microfiller is a fine powder with a particle size less than 80 microns. Normal Portland cement concrete, on the other hand, usually achieves about 20 of its 28-day strength in one day. The use of steel, glass, polypropylene, and nylon fibres has been reported in the literature.
Davidovits proposed that binders could be produced by a polymeric reaction of alkaline liquids with the silicon and the aluminum in source materials. PDF Polymer concrete is a composite material realized with resin and aggregates. In the present study the epoxy resin was used for binding the aggregates. In the composition were introduced near the fly ash, used as filler, the cellulose fibers. As Polymer Concrete is finding new applications in addition to their basic use in civil application.e.

MMA has got a limited application because of its higher flammability and disagreeable odour; however, it has received some attention because of its good workability and low temperature curability. Thorotop HCR cement based worn off in high traffic areas transverse and alligator cracking limited skid resistance, silica fume concrete in use for only a year, incomparable data. Enhancement in compressive strength up to 30 has been reported with addition of 15 fly ash in polymer concrete. Various methods of application of silane agents like integral blend method and surface treatment method have been compared 24, 51,. Testing, examples of Failures, why Use Overlays? It was observed that silane treatment of fibers before addition into polymer concrete further enhances its mechanical properties. Variation of compressive strength of polymer concrete for various types of resins and their dosage has been reported in the literature. Fatigue behaviour of polymer concrete has been described based upon - relationships. It has been reported that when using integral blend method of silane addition, 1 silane by the weight of resin gives optimum results 53,.
