KELCO-CRETE® diutan
gum is an anionic polysaccharide developed specifically for use with cementitious
materials and the newest class of superplasticizers. It enables formulators
and designers to improve the
performance of hardened materials by controlling flow, segregation, sedimentation,
and bleed.
KELCO-CRETE diutan gum belongs to a class of rheology modifying
agents possessing pseudoplastic behavior. Pseudoplastic materials are
characterized by viscosity which increases and decreases virtually instantaneously
in response to the removal and application of shear. This property results
in fluids which readily flow but are capable of suspending or stabilizing
components.
BENEFITS
| •
Exceptional sedimentation control |
• Reduced sag
on vertical surfaces |
| • Eliminates
flotation of lightweight materials |
• Easy to mix and pump into
place |
• Stabilizes
components during hardening for
|
• Easy to spread and finish |
| improved bonding
and hardened properties |
• Reduces impact of raw
material variability |
APPLICATIONS
KELCO-CRETE diutan gum is ideal for use in
admixtures for highly fluid
yet stable cementitious pastes, such as:
| •
Self-consolidating concrete (SCC) |
• Gypsum-based |
|
| • Self-leveling
floors |
floor screeds |
|
| • Underwater
concrete |
• Grouts
and mortars |
|
| • Geotechnical
grouts |
• Precast concrete |
