DESCRIPTION:
CHEMITO SIGMA FLOW 2880 is the latest development of superplasticizer for concrete. It meets the requirements for high range water reducing superplasticizers.

STANDARDS:
CHEMITO SIGMA FLOW 2880 complies with ASTM C 494-1981 Type G

DOMAINS OF APPLICATION/USES:

• CHEMITO SIGMA FLOW 2880 can be used for:
• All cement and cementitious material
• Ready mix concrete
• Provides high water reduction and improved fresh concrete characteristics
• Unique multipurpose superplasticizer
• Single admixture for wide range of concrete
• Concrete at mild to cold temperatures
• Highly efficient concrete applications

ADVANTAGES:

• CHEMITO SIGMA FLOW 2880 provides the following beneficial properties:
  • Substantial improvements in workability Flow properties without any increase in water, produces self-compacting concrete
  • The bond strength of concrete to reinforcing steel is considerably increased.
  • Extended workability in conjunction with subsequent strength development.
  • Very significant water reduction minimizes shrinkage or cracking, producing close textured impervious concrete with improved durability and surface finish.
  • This is of particular importance in liquid retaining and water bearing structures.
  • Surface water, water under pressure and aggressive atmospheric conditions.
  • For a given concrete mix keeping the cement consumption and workability constant, large reduction in the amount of mixing water can be achieved.

HANDLING:
CHEMITO SIGMA FLOW 2880 is formulated from chemicals, which present no fire or health hazards.
