Sika® Plastocrete®-161 HE

Sika® Plastocrete®-161 HE

ACCELERATING ADMIXTURE

Sika® Plastocrete®-161 HE is a set accelerating admixture formulated to reduce concrete set times. Sika® Plastocrete®-161 HE contains calcium chloride. Sika® Plastocrete®-161 HE meets the requirements of ASTM C-494, Types C and E.

Cold Weather Concreting: When Sika® Plastocrete®-161 HE is added to the mix, set times of cold weather concrete approach those of normal weather conditions.   In case of freezing conditions, cold weather concreting practices as specified in ACI 306 - Standard Specification for Cold Weather Concreting should be followed.    Accelerated Set Times and Strength Development: Sika® Plastocrete®-161 HE may be used to accelerate setting times where job-site efficiency is important in order to maintain construction deadlines.    Reduced setting and curing times offer significant economies in the following areas:
  • Insulation and heating costs during curing times are reduced.
  • Accelerated setting times allow crews to finish concrete earlier and save time and costs for finishing operations.
  • Earlier stripping and reuse of forms increase labor productivity and reduce job site labor costs.
  • Accelerated strength gain allows earlier structural use of concrete and speeds up project completion time.

Application

Application Information

Mixing

Measure the required quantity manually or by automated dispenser. Add into the water line at the batch plant or directly to the mixer at the end of the batching cycle. When used in combination with other admixtures, care must be taken to dispense each admixture separately into the mix. Do not mix with dry cement.

   

Combination with Other Admixtures: Sika® Plastocrete®-161 HE performs effectively as single admixture or in combination with other admixtures in the Sika System.
Consumption

Recommended Dosage

Dosage rates of 6-64 fl. oz. 100 lbs. (390–4160 ml / 100 kg) cementitious are recommended for most applications. When dosage used is more than 16 fl.oz. / cwt. adjust mixing water accordingly.
