Polymer Concrete - What is it?
The incredible and unique physical properties of polymer concrete give rise to an infinite number of design and adaption possibilities.
In brief the material is a silica based concrete that uses epoxy resin as a binding agent rather than cement. This gives it far superior and desirable properties to the cement based product:
- As strong as fully cured standard concrete but cures to full hardness and has structural integrity within [12] hours.
- Is impervious to oil, dust, grease and grime.
- Uses all forms of sand (eg local desert sand etc) with no loss of strength
- The plant that produces it is transportable and operational on site. This allows the local production to work in a JIT methodology whilst at the same time being to react immediately to local changes/needs.
- It can be formed/molded into practically any component shape/size whilst still maintaining its integrity and strength.
- Can produce highly attractive finishes in the mould process (e.g. high gloss, colored, sparkling, luminescent etc) thus removing the need/cost of a separate decoration stage(s).
- Hence it is an incredibly flexible building product, one day the plant can produce easily interlocking building blocks, whilst the next producing attractive floor and wall tiles or roof tiles.
Raw materials for production are:
- nonsaturated polyester resin (epoxy resin) as a binder
- Fillers (free-flowing mineral substances)
- reagent such as curing agents, accelerators
- Additives / Inhibitors
- color pigments, finish effect materials
Because the production of Polymer Concrete will vary according to the to the type of resin and other materials and quantities used (e.g. type of sand/filler etc). Hence the products produced will have varying properties both physical and mechanical. For instance the polyester resin functions as the bonding agent between the individual components and encapsulates all of the composite materials completely. Therefore the corrosion resistance of the overall material is directly related to the resistance of the resin used. So the exact characteristics of the eventual product will vary according to the resin/binder; the type and grain size of the filler; the type of glass fibers and the compression and curing mold used to shape the final product.
By the very precise control of curing agents and accelerators, and various additives/inhibitors the polymerization process can be accurately controlled to produce the characteristics required for each individual job. The final product being visually enhanced by the addition of color pigments, gelcoats and effect materials if required.
