Mortar and grout modifiers
mortierdegrader The Main application are:
  • Concrete repair mortars
  • Renders and finishing grouts
  • Self levelling flooring systems
  • External thermal insulation

One will seek the following performances:
  • Improvement of the workability & of the rheological behaviour in the we state
  • Reduction of the water demand
  • Increase of wet & dry adhesion
  • Increase of water & chemical resistance
  • Increase of abrasion resistance
  • Reduction of elastic modulus / Increase of flexural strength

For these specific needs CRAY VALLEY recommend especially the use of:
Type Tg (°C) Function
fleche Craymul 5150
+12
  • Workability
    Adhesion
fleche Craymul 5525
+17
  • Workability
    Waterproofing


Main properties of polymer modified mortars :
CR 5150 CR 5525
Wet state
  • Redcution of water demand
  • Good workability and appropriate rheological behaviour (pseudoplastic)
  • Wet adhesion to the substrates
  • Do not require moist curing conditions
 Wet state
  • Remarkable rediction of water demand
  • Very good workability and appropriate rheological behaviour (newtonian)
  • Wet adhesion to the substrates
  • Do not require moist curing conditions
Dry state
  • Lower elastic modulus / higher flexural strength without losses in compressive strenght
  • Improved adhesion
 Dry state
  • Lower elastic modulus / higher flexural strength without losses in compressive strenght
  • Very high water resistance
  • High abrasion resistance
  • Improved chemical resistance
