Are you tired of using cement as a binding material for your concrete? Well, the good news is that there’s an alternative. A more durable and safer option to go for.
Polymer concrete has been in existence since the late ’50s. Its use gained traction by the end of the ’70s. However, some people still don’t understand the working mechanisms of this concrete in the contemporary world.
If you are among those people then worry no more. This article will help you get a grip on polymer concrete in terms of its features, applications, and benefits. Dive in to learn more.
The materials for preparing polymer concrete are almost similar to those you use for precast concrete. The major difference arises from the type of binder that you’ll use. Polymer concrete utilizes polymer resin as a binder, unlike ordinary concrete which uses cement.
Common aggregates for polymer concrete include silica, granite, limestone gravels, and quartz. The common resins for binding these aggregates are methacrylate, vinyl ester resin, polyester resin, and epoxy resin. Polyester resin is the most common binder because of its ease of availability and excellent mechanical properties.
It’s important to note that mixing these aggregates and the resins requires precision and thoroughness. This is because it’s impossible to mix polymer concrete beforehand like the case of conventional concrete. The curing process will proceed anyway if you try this polymer concrete.
This concrete has unique characteristics that make it attractive. Polymer concrete cures rapidly and takes a single day to develop a substantial amount of strength under room temperature.
This is unlike conventional concrete which takes 28 days to develop its strength. Polymer concrete has better strength and adhesion properties because of the resins. This concrete is more structurally sound than ordinary concrete with similar characteristics.
The resins in polymer concrete reduce the number of pores. This enables the concrete to develop low permeability properties. It’s, therefore, able to prevent water and other chemicals from infiltrating into it.
This makes it more durable as it is less susceptible to chemical attacks. It’s also able to withstand the adverse effects of the freezing and thawing actions of water.
The many polymer concrete benefits make it have diverse applications. Most of these applications fall under specialized construction projects. These are the kinds of projects that require durable and corrosion-resistant materials.
Some of the applications are:
- Construction of nuclear power plants
- Construction of electrical and industrial structures
- Desalination plants and sewage works
- Prefabrication of acid tanks, highway median barriers, drains, and manholes
- In marine works
There are 3 common types of polymer concrete. The first one is the polymer impregnated concrete; it’s produced from Portland cement and polymerized in situ. The other two are polymer cement concrete and polymer concrete.
Try substituting ordinary concrete with polymer concrete. You’ll enjoy a superior structural performance that will last for a longer time.
Besides, polymer concrete applications are diverse. You can use this concrete in a variety of fields.
