Elemix Concrete Additive

Product Overview

Product Description, Applications

Elemix® additive is a new, lightweight synthetic particle (LSP) that contains polymeric spheres specially formulated for use in concrete. With a closed cell inner structure that contains air and a maximum of 5.5% water absorption by weight, Elemix additive allows the creation of lighter weight, durable, energy-efficient concrete with improved performance and enhanced thermal and crack resistance properties.

Available in Type XE (white) and Grey XE (grey), Elemix additive meets applicable compressive strength, flexural strength, consistency, freeze-thaw resistance and scaling-deicing requirements for many commercial concrete applications, including:

  • Structural and non-structural concrete
  • Ready-mix in grouts and fills
  • Poured-in-place concrete
  • Elevated decks and toppings
  • Manufactured concrete products
  • Precast components

Added during the concrete batching process, Elemix additive distributes uniformly in concrete with regular mixing due to its dynamic structure and dispersion characteristics, becoming an integral part of the concrete matrix. It is placed and finished using traditional methods, and because of its lightweight properties, allows builders to consume less material overall, resulting in reduced construction costs.

Environmental Benefits:

  • Improves thermal performance for increased energy-efficiency
  • Reduces building and transportation costs
  • Design flexibility increases the opportunity for a structure to be repurposed, resulting in a longer lifespan
  • Concrete made with Elemix additive can be recycled for use in many applications
  • Eligible to contribute points in up to six LEED® categories


  • Resists cracking
  • Enables architects and engineers to create spaces with better usable square footage
  • Elemix additive is registered as a ‘Classified’ Material in the Underwriters Laboratories (UL) fire directory and is registered as ‘Listed’ in the Underwriters Laboratories of Canada (ULC) directory
  • Meets ASTM requirements for structural concrete
  • Inert and without a shelf life limit when stored according to manufacturer recommendations
