• Construction Dry-mix Filler Materials

Magnesium Oxide

• XP Mag (MEA) Mineral Expansive Admixture is used to counter autogenous and drying shrinkage cracks.

  The inclusion of XP Mag (MEA) can significantly reduce the shrinkage of cement slurry and increase the free expansion. This strategy not only minimizes the need for crack repairs but also results in reduced maintenance costs, enhanced construction sequencing, improved durability, and increased resistance against water and chemical ingress. As a result, the benefits of XP Mag inclusion can be decreased or eliminated crack repair time and cost, lower maintenance costs, advantages for thin sections and overlays, extended joint spacing, shortening construction timelines, and increase of the expected service life of concrete.

  The Versatile Applications of XP Mag:

  • In Dams, Water Infrastructure, and water treatment facilities, durability and structural integrity are non-negotiable. The inclusion of XP Mag in concrete can ensure these critical infrastructures can withstand the test of time by preventing shrinkage cracks, thus enhancing their resilience against environmental stresses, and extending their service life.
  • Bridge decks and elevated slabs are subjected to constant load and environmental variations, making them vulnerable to cracking. XP Mag’s ability to compensate for concrete shrinkage ensures these structures maintain their integrity and safety for longer periods, reducing the need for frequent repairs.
  • Shotcrete Applications
  • In tunnel linings, mining operations, and slope stabilization, shotcrete is preferred for its ease of application and versatility. Incorporating XP Mag into shotcrete mixes could significantly improve its performance by minimizing shrinkage cracks, ensuring stability, and enhancing durability.
  • Slabs, Airport Runways, and Pavements demand a concrete solution that can resist cracking under thermal, mechanical, and shrinkage stresses. XP Mag’s shrinkage-compensating properties ensure a smoother, more durable surface capable of handling heavy loads and high traffic volumes.
  • In the realm of architectural concrete, aesthetics is as crucial as structural integrity. XP Mag allows for the creation of visually striking elements without the compromise of unsightly shrinkage cracks, enabling architects and designers to push the boundaries of creativity.
  • Packaged Materials and Secondary Containment using XP Mag, extends to packaged materials, offering enhanced performance in pre-mixed concrete products, and secondary containment structures where leak prevention and chemical resistance are critical.
