Mechanical properties

Mechanical properties Imerys minerals for improved mechanical properties in concrete and fiber board


Used as a reinforcing agent in concrete, metakaolin provides:

  • Higher cured compressive strength

Where high strength concrete is required, Imerys metakaolin increases cured compressive strength of concrete and speed up curing and early strength development, making it ideal for applications where high strength is required quickly such as airport aprons.

  • Improved mechanical properties in Portland cement-based concrete

Premium pozzolanic metakaolin products provide improved strength, durability, workability and finish in Portland cement-based concrete. We recommend our Argical-M product range for concrete.

Fiber board

Imerys wollastonite and mica can be used to control dimensional stability, thermal shrinkage and board integrity in fiber cement and silicate board enabling boards to meet strict dimensional stability performance criteria for use in wet rooms and fire-resistant applications.

We recommend our Nyad® wollastonite and Suzorite® mica ranges for fiber board.

We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
