Intracrete EH-V AE

CABLE GROUT ADMIXTURE

Intracrete EH-V AE is a cable grout admixture in powder form. It introduces micro bubbles into the mix. Thereby promoting wet volume expansion and improves flow of the mixed grout without segregation.
Suitable for use in tropical and hot climatic conditions.

Intracrete EH-V AE has the following characteristics:
  • Improved flow
  • Does not contain chlorides and sulphates
  • Increased cohesion
  • Nitrogen gas system for volume expansion in wet state
  • Slight retardation to extend open time

Usage

Intracrete EH-V AE may only be used by experienced professionals. Intracrete EH-V AE is used to increase the cohesion in cementitious grouts (addition of sand is possible).
Intracrete EH-V AE can be used for grouting of:
  • Post tensioning cables
  • Pre-stressed cable ducts
  • Rock and concrete anchor bolts
 

Advantages

Intracrete EH-V AE has the following characteristics:
  • Improved flow
  • Does not contain chlorides and sulphates
  • Increased cohesion
  • Nitrogen gas system for volume expansion in wet state
  • Slight retardation to extend open time
