SikaPlast®-400 IQ

Set retarding, water reducing & plasticizing admixture

SikaPlast®-400 IQ is a Set retarding, water reducing & plasticizing admixture for Concrete & Mortar utilizing Sika’s ‘ViscoCrete®’ polycarboxylate polymer technology ( 3rd Generation ).

  1. Water reduction, resulting in higher density, higher strength and reduced permeability.
  2. Easier and faster pumping of concrete.
  3. Increased workability and easier placeability.
  4. Increased concrete durability and uniformity.
  5. Reduced shrinkage and cracking.
  6. Reduced rate of carbonation of the concrete.
  7. Improved slump retention eliminates need to add water to concrete at the job site.

Technical Information

Concreting guidance

The standard rules of good concreting practice, concerning production and placing, are to be followed. Laboratory trials shall be carried out before concreting on site, especially when using a new mix design or producing new concrete components. Fresh concrete must be cured properly and curing applied as early as possible.

Application

Application Information

Dispensing

SikaPlast®-400 IQ  is added to the gauging water or added with it into the concrete mixer. To take advantage of the high water reduction, a wet mixing time, which is depending on the mixing conditions and mixer performance, of at least 3 mins. per cubic meter after the admixture addition is recommended. SikaPlast®-400 IQ shall not be added to dry cement.

Compatibility

SikaPlast®-400 IQ can be used in conjunction with : 

  1. Sika®Aer
  2. Sika ViscoFlow®
  3. Sika® ViscoCrete®
  4. SikaPlast®
  5. Sika® Retarder IQ
  6. SikaFiber®
  7. Sika® Plastocrete® N IQ

 All admixtures must be added separately. Trials are always recommended before combining products . For additional information, please contact Sika technical personnel. 
Consumption

Recommended dosage

( 0.5 % - 2.5 % ) by weight of total cementitious materials.
