Sikament®-520N

High Range Water-Reducing and Set Retarding Concrete Admixture

Sikament®-520N is a highly effective superplasticizer with a set-retarding effect for producing free-flowing concrete in hot climates. Also, a substantial water reducing agent for promoting high early and ultimate strengths.

Sikament®-520N provides the following properties:

As a Superplasticizer:
  • Substantial improvement in workability without increased water or the risk of segregation
  • Longlasting control of slump loss.
  • No adverse effect on ultimate strengths
As a Water Reducer:
  • Early strengths significantly increased
  • High ultimate strengths
  • Up to 30% water reduction
  • Especially suitable for hot climates
  • No excessive air-entrainment
  • No adverse shrinkage effect
  • Improved surface finish
  • Increased watertightness

Application

Application Information

Compatibility

Sikament®-520N is compatible with all types of Portland Cement, including S.R.C. type and Hydraulic Cement.

Dispensing

Sikament®-520N can be added separately to the freshly mixed concrete or directly to the mixing water prior to its addition to the aggregates. When added separately to the freshly mixed concrete, further mixing should take place for at least one minute per cubic meter.
Consumption

Recommended Dosage

800 - 2,500 cc. per 100 kg. of cement weight. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, Water/Cement-ratio and ambient temperature.Therefore, it is advisable to carry out trial mixes.
