SikaCem® Accelerator

Sikacem® Accelerator is a non-chloride hardening accelerator formulated to increase the early strength of concrete, mortars and grouts without affecting the initial workability. Sikacem® Accelerator meets the requirements of ASTM C494 Type C accelerating admixtures, and AASHTO M 194 Type C.

  • ƒƒMay be used with SikaGrout®-212, SikaGrout®-212 HP, SikaGrout®-300 PT and SikaGrout®-277 Cable grouts.
  • May be used with SikaQuick®, Sikacrete®-08 SCC/-211 Flow PLUS, SikaTop®-111/-122/-123 PLUS and Sika MonoTop®-623 F repair mortars
  • Early stripping and re-use of forms
  • Faster finishing operations on flatwork surfaces
  • Effective with Type GU, Type MS, and Type HE cements
  • Increases early strengths and allows faster repairs
  • Canadian Food Inspection Agency acceptance (CFIA)

Sikacem® Accelerator delivers excellent results when high early strengths are required. Curing times are significantly reduced while concrete quality is improved.


Cold weather concreting: Sikacem® Accelerator is an effective hardening accelerator where high early strength concrete is desired and the use of calcium chloride is prohibited. See individual Product Data Sheet for specific dosages and limitations.

 

  • ƒƒMay be used with SikaGrout®-212, SikaGrout®-212 HP, SikaGrout®-300 PT and SikaGrout®-277 Cable grouts.
  • May be used with SikaQuick®, Sikacrete®-08 SCC/-211 Flow PLUS, SikaTop®-111/-122/-123 PLUS and Sika MonoTop®-623 F repair mortars.
  • Insulation and heating costs for curing time can be reduced.
  • Earlier stripping and reuse of forms increases labor productivity.
  • Accelerated strength gain allows earlier structural use and speeds completion time. Sikacem® Accelerator does not contain calcium chloride or any other intentionally added chlorides and will not initiate or promote the corrosion of reinforcing steel present in the concrete.

Placing concrete in freezing conditions: When used at Sika recommended dosage rates, Sikacem® Accelerator may reduce the need for cold weather concreting practices as specified in ACI 306 - Standard Specification for Cold Weather Concreting.


Field evaluations should be carried out when concrete is to be placed in freezing conditions to determine the minimum ambient and concrete temperatures required, and the optimum dosage for the desired setting time and strength performance. Sika strongly recommends that appropriate sound curing practices be followed to protect fresh concrete from excessive heat loss in extreme weather conditions.
