Cement

WACKER offers a broad portfolio of products and solutions that make cement more durable and sustainable. These products can be used to improve storage stability, prevent prehydration during production and help improve the mechanical properties of cementitious dry-mix mortars.

WACKER offers a variety of VINNAPAS® polymer dispersions and SILRES® silicone powder additives that are ideal for modifying all kinds of mortars and grouts to improve their properties, especially in critical applications.

Benefits:

  • Excellent compatibility with cement
  • Increased flexural strength and lower e-modulus (elastic modulus)
  • High green strength
  • Excellent workability with a long pot life
  • Water repellency and bulk hydrophobization

Applications:

  • Modification of on-site mortars
  • “Add-on” dispersions to improve adhesion, cohesion and durability of critical substrates or to meet increased performance requirements

SILRES® BS silicone additives improve the properties and storage stability of cement in the long term. Usually added during the cement production process, high-performance SILRES® BS organosilicone additives are very effective in making cement impervious to surrounding moisture.

Benefits:

  • Excellent compatibility with cement
  • Treated cement introduces hydrophobic properties into cement-based products
  • Prevention of cement prehydration
  • Improved anti-caking, flowability properties of cement
  • Saves energy by further reducing grinding energy and increasing mill throughput

Applications:

  • Treatment of cement during the grinding process to produce hydrophobic cement
  • Stabilizing cement against prehydration during storage, specifically in bags, even in humid climates
