Polymer Concrete

Definition - What does Polymer Concrete mean?

Polymer concrete is an alternative to portland cement that is used to bond a mixture of aggregates together with epoxy binders. It is used in construction projects to provide added strength and can be modified with a range of resins. Polymer concrete provides very good resistance against corrosion and minimal chemical reactivity.

Corrosionpedia explains Polymer Concrete

A polyester, vinyl resin or epoxy resin is often used to manufacture polymer concrete. This allows the concrete to be poured, then hardened. Polymer concrete cures through a chemical reaction with the polymer material. This type concrete is ideal for reaching areas that are not easily accessible.

Polymer concrete offers a range of benefits depending on the resin used to make it. Acrylic resins set quickly and offer resistance to harsh weather conditions, while epoxies create a strong material with little curing shrinkage. Furan resins can withstand high temperatures, and polyurea resins can replace formaldehydes or other hazardous compounds for construction purposes.
