SikaControl®-3323 A

(former MasterCast® 3323)

High Performance Plasticizer Admixture for Plaster Mortars

SikaControl®-3323 A is a high-performance micro air entraining mortar admixture designed to improve impermeability, workability, and Freeze-Thaw resistance in plaster mortars.
SikaControl®-3323 A also acts as a dual-purpose high-performance plasticiser and deflocculating agent with controlled retardation.

  • Has homogenous air entraining property.
  • Reduces placing problems in hot weather concreting, by improving workability and workability retention.
  • Improves resistance to Freeze-Thaw attack.
  • Improves trowelability and surface finish.
  • Improves pumpability of concrete.
  • Reduces permeability.
  • Enables economical mix designs

Usage

  • In inner-outer spaces for vertical applications.
  • In plaster mortars to reduce permeability.
  • In brick and stone coating mortars for improving workability.
  • Hot weather concreting, where controlled delay to initial set is of prime importance.
  • Ready-mix mortar concrete, where workability retention coupled with retardation of initial set are beneficial.

System information

Compatibility

SikaControl®-3323 A can be used with all types of Portland cement, including SRC. For use with other special cements, contact the Sika Technical Services Department.
SikaControl®-3323 A should not be pre-mixed with other admixtures. If other admixtures are to be used in conjunction with SikaControl®-3323 A, it must be dispensed separately. Consult the Sika Technical Services Department for advice.
Technical Information

Effect on Setting

SikaControl®-3323 A acts efficiently to give controlled retardation of initial set. Setting times of mortar mixes are related to cement type and ambient temperatures.

A severe over dosage of SikaControl®-3323 A will result in the following:

  • Retardation of initial and final set.
  • Slight increase in air-entrainment.
  • Increase in workability.

Provided it is properly cured, the ultimate strength of the concrete will not be adversely affected and will generally be higher than for normal concrete. The retarding effects of very high dosages will be exaggerated with SRC.

Application

Application Information

Dispensing

SikaControl®-3323 A is introduced into the mixer with the mixing water. The admixture works more efficiently if it is added to the dampened mix after 50-70% of the water has been introduced. No extension to normal mixing time is necessary.
SikaControl®-3323 A should never be added to dry cement.

 
Consumption

Recommended Dosage

In all cases, we recommend that trial mixes are carried out to determine the correct levels of admixture required to achieve the desired concrete properties. SikaControl®-3323 A is normally dispensed, depending on the desired plasticising or water-reducing effect, at a rate of:

200 - 1000 ml/100kg cementitious content. Other dosages may be used, depending on the materials and conditions. In this case please consult our Technical Services Department for advice.
