Polymer concrete its 5 Components & Benefits
It is not like traditional concrete, although polymer concrete uses some of the same types of materials. It is used for many construction projects in the same manner. Still, the polymer compounds give several concrete characteristics that tend to make it safer or more durable than simple concrete. On the other hand, it tends to be more expensive than the traditional version and is measured more specifically in shrinkage and density.
Definition
It is an aggregate mixture that uses some polymer type of epoxy binder to harden and cure into place. A polyester, standard vinyl ester, or epoxy mixture is often used. Still, It can be made with several polymer resins that allow the concrete to be poured or troweled and then hardened. Polymer concrete cures through a chemical reaction with polymer materials. Like traditional concrete, it also has water, crushed stone or gravel, and sand as primary ingredients.
Uses
It is used for several types of specialized construction projects. Like other kinds of concrete, polymer concrete can join two different components or provide a base or structure. The material is used in industrial construction or electrical where the concrete needs to last a long time and be resistant to many types of corrosion.
Benefits
It offers different benefits depending on the resin used to make it. While epoxies polymer creates a solid material that shrinks very small as polymer cures, Acrylic binders offer resistance to set and weathering very quickly. In addition, furan resins can withstand high temperatures, and polyurea resins can replace phenolics or formaldehyde used in many construction projects.
Considerations
Polymer concrete must be mixed very thoroughly or very precisely. Polymer concrete cannot be mixed simply and beforehand kept turning to avoid curing. The chemical reaction will happen no matter. Also, the chemicals that this type of concrete uses can be hazardous, and everyone nearby must-have skin protection and wear masks.
Polymer Mortar
It is a smoother polymer concrete made only from a fine aggregate and a binder, like sand. Polymer mortar is mixed primarily to join objects, like regular mortar. However, polymer mortar may also be used to coat objects for protection.
Polymer properties:
Polymers’ properties depend on their chemical structure and molecular mass. Polymer concrete properties depend on the molecular mass of a hypothetical polymer. Being cross-links in polymer chains improves their mechanical properties. In thermoplastic polymers with no cross-link, polymer chains slip on one another because of Vendor forces, and heat or power between them disappears.
Crosslink in thermoset polymer concrete restricts polymer chain relative movement, and polymer can be considered under power shapeshift; in this polymer, concrete is like a three-dimensional network under power shapeshift. Polymer chains move a little from each other by electric or heat charge in thermoset polymers. But the crosslink won’t be distinguished. In a chain in thermoplastic polymer, chains split on each other, and the polymer loses its solid state or Heat causes displacement in a part of the chain.
Polymer concrete component
Aggregate:
Aggregates in polymer concrete must have the highest quality. Therefore, aggregates of high-quality limestone, silica, quartz, granite and other fine aggregates with good quality are suitable for polymer concrete.
Polymer splicer:
According to polymer concrete, any polymer splicer used polymer glue in polymer concrete. Usually, thermosets are used as polymer splicers, But according to what features are expected from polymer concrete.
Epoxy:
They are usually contained in one hardener, resin, reaction retardants, and sometimes inorganic Thixotropic or fillers. Epoxies are the most common polymer splicer which is used in polymer concrete.
Polyester:
Polyester features are:
- Shrinking during operation of Relatively.
- Polyesters don’t have good stickiness to humid and wet surfaces. Although recent researches show that a kind of polyester, Vinyl ester, can be used on wet surfaces.
- Some polyesters have low resistance against the soluble and alkali,
- Polyesters are usually flammable at 37 C. The primer (hardener) used for polyesters disintegrates quickly over 31 C and might cause an explosion or fire.
Acrylics:
Acrylics, also known as Methyl methacrylate features are so many like polyesters.
