SikaMix AE-6

SikaMix AE-6 meets the requirements of ASTM E514 - Standard Test Method for Water Penetration and Leakage Through Masonry.

6 months when stored in dry warehouse conditions, at temperatures between 10 and 21 °C (50 and 70 °F).

If the product separates or settles during this period, reconstitute the product to normal state by agitation. If frozen, admixture cannot be reconstituted and must be discarded accordingly to local laws.

As SikaMix AE-6 is a low dosed admixture and since the majority of drycast concrete will have a very low water cement ratio/moisture content, it is necessary to provide sufficient mixing time to allow the admixture to be distributed throughout the entire batch and provide uniform performance.

In general, a total mixing time of at least 90 seconds is essential. Mixing time after adding the admixture depends on the individual circumstances and should be determined by trials.

When added to ready mix concrete truck, ensure sufficient mixing time for uniform admixture distribution throughout the concrete.

SikaMix AE-6 can be added with the batching water or introduced at the end of the mixing process.

Do not introduce SikaMix AE-6 up front, or directly onto dry cementitious materials, as this may reduce admixture performance.

Dosage rate will vary according to targeted application. Normally a dosage range of 225 to 520 mL/100 kg (3.5 to 8 fl. oz./100 lbs.) of cementitious material should be sufficient for efflorescence and absorption control. If water repellency is required dosage may be increased to 325 to 650 mL/100 kg (5 to 10 fl. oz./100 lbs.) of cementitious material. Actual dosage rate will vary based upon mix design. Proper dosage should be always verified by trial batch to ensure desired performance is achieved.

  
Dosages outside the recommended range may be used for special requirements and applications. Contact your Sika Canada Technical Sales Representative for further information.
