SikaCem® Accelerator

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.

  • May 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)

Usage

High Early Strength Concrete: Sikacem® Accelerator delivers excellent results in normal and hot weather conditions where very high early strengths are required. Conventional accelerators promote early stiffening of the concrete, making it unworkable within a short period of time. Sikacem® Accelerator is designed for applications where early stiffening (slump loss) is not desirable but high early strengths must be obtained within a specified time.

FAQ

How to perform concrete finishing and curing with Sikacem® Accelerator?

Finish and cure Sikacem® Accelerator concrete, mortars, and grouts in accordance with sound concreting practices as specified in ACI 302 and 308. For placement in sub-freezing temperatures, Sikacem® Accelerator may be used to speed finishing and curing times per ACI 306 - Standard Specification for Cold Weather Concreting.

Also, Insulation and heating costs for curing time can be reduced while concrete quality is improved. Accelerated strength gain allows earlier structural use and speeds up completion time.
 

Do I have to put too much water when mixing with Sikacem® Accelerator?

Reduce water content by same volume of Sikacem® Accelerator addition rate. Do not over water mix.

Is it possible to mix Sikacem® Accelerator with dry cementitious material?

Add correct amount of Sikacem® Accelerator at the job site. The admixture may be added directly into the mixing water liquid. Do not mix with dry cementitious material.

What is the dosage rate of Sikacem® Accelerator when used to protect concrete from freezing?

When used to protect concrete and mortars from freezing, use two (2) bottles of 150 mL (300 mL total) per bag of Sika® cementitious material.

What is the dosage rate of Sikacem® Accelerator?

To promote high early strength Sikacem® Accelerator may be used at the rate of one (1) bottle of 150 mL per bag of Sika® cementitious material.

Note: For SikaGrout®-212 and SikaGrout®-212 HP, using 2 bottles of accelerator will diminish the expansive properties. Contact Sika Canada for further details.
 

When using Sikacem® Accelerator with concrete placed in freezing conditions, should we use cold weather concreting practices?

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 the excessive heat loss in extreme weather conditions.

Sikacem® Accelerator can be effective with what kinds of cement?

Sikacem® Accelerator is effective with Type GU, Type MS, and Type HE cements

Sikacem® Accelerator can be used with what kind of repair mortars?

Sikacem® Accelerator may be used with SikaQuick®, Sikacrete®-08 SCC/-211 Flow PLUS, SikaTop®-111/-122/-123 PLUS, and Sika MonoTop®-623 F repair mortars.

Sikacem® Accelerator can be used with which grout?

Sikacem® Accelerator may be used with SikaGrout®-212, SikaGrout®-212 HP, SikaGrout®-300 PT, and SikaGrout®-277 Cable grouts.

Note: For SikaGrout®-212 and SikaGrout®-212 HP, using 2 bottles of accelerator will diminish the expansive properties. Contact Sika Canada for further details.
 

Is Sikacem® Accelerator designed for applications where early stiffening (slump loss) is not desirable?

Sikacem® Accelerator is designed for applications where early stiffening (slump loss) is not desirable but high early strengths must be obtained within a specified time.

Does Sikacem® Accelerator contain chloride?

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.
