Sika® Plastiment®-88

WATER REDUCING AND SET RETARDING CONCRETE ADMIXTURE

A concrete plasticizer and retarder based on modified lignosulfonates used to produce good quality concrete.
Complies with ASTM C494 Type D.

  • Only set retarding, does not delay the hardening process
  • Allow substantial cement reduction compared to plain concrete
  • Increase in ultimate strength
  • Good control of slump loss even at elevated ambient temperature
  • Reduced shrinkage and creep

Usage

Sika® Plastiment®-88 is used in structural and mass concrete where long setting times and improved workability are required, such as projects with:
  • Large pours, to prevent formation of cold joints
  • Long travel times from the concrete plant to the site
  • Difficult placing conditions and details
  • High ambient temperature
 

Advantages

  • Only set retarding, does not delay the hardening process
  • Allow substantial cement reduction compared to plain concrete
  • Increase in ultimate strength
  • Good control of slump loss even at elevated ambient temperature
  • Reduced shrinkage and creep

Technical Information

Concreting Guidance

Concrete placing: With the use of Sika® Plastiment®-88, concrete of highest quality is being produced, however state of the art concrete technology, such as mixing, placing vibrating and curing must be respected and applied
Curing: Effective measures for concrete curing must be followed

 

Application

Application Information

Compatibility

Sika® Plastiment®-88 may be combined with all Sikament®, Sika® Aer, Sika®Pump, Sikacrete® PP1 products, but must be added separately to the mix and not pre-mixed prior its addition
Sika® Plastiment®-88 is compatible with all Portland Cement types

DISPENSING

Sika® Plastiment®-88 is added to the gauging water prior to its addition to the dry mix or added separately to the wetted concrete mix.

For optimum utilization of the ultra-high range water reducer we recommend a minimum wet mixing time of 60 seconds.

 

When adding the balance of the batching water to adjust concrete consistency this should be done after a minimum of 2/3 of the wet mixing time to avoid surplus water in the concrete.
Consumption

Recommended Dosage

0.4 – 1.5 ltr per 100 kg of cement/binder

Typical 0.5 to 1.4 ltr/100 kg of cement/binder

For semi-dry concrete, typical 0.8 to 1.4 ltr/100 kg of cement/binder
