Sika® ViscoCrete® ACE 415

(former MasterGlenium® ACE 415)

A new generation high-performance polycarboxylic ether-based superplasticizer for the Precast industry

Sika® ViscoCrete® ACE 415 (Admixture Controlled Energy) consists of a range of innovative superplasticizers based on newly developed polycarboxylate ether polymers. The particular molecular configuration of Sika® ViscoCrete® ACE 415 accelerates the cement hydration by exposing increased surface of the cement grains to react with water. As a result, it is possible to obtain earlier development of the heat of hydration, rapid development of the hydration products and, therefore, higher strengths at very early age.
The polymer structure of Sika® ViscoCrete® ACE 415 is specially designed to improve the rheology of precast concrete, making it very flowable and low viscous even at very low water/cement ratios, without increasing stickiness. Robustness is a distinctive feature of the precast concrete produced with Sika® ViscoCrete® ACE 415.

Sika® ViscoCrete® ACE 415 offer the following benefits for the precast concrete industry:
  • Production of highly flowable, robust selfcompacting concrete having a low water cement ratio along with an optimal rheology.
  • Enhanced robustness and consistency in concrete quality with low stickiness.
  • Environmentally friendly, CO2 reduced mix- design optimization.
  • Elimination of heat curing.
  • Improved surface appearance.
  • Durable precast concrete elements as per EN 206-1.
  • Elimination of the energy required for placing, compaction and curing.
  • Optimization of the curing cycles by reducing curing time or curing temperature.
  • Increased productivity.

System information

Compatibility

Sika® ViscoCrete® ACE 415 is compatible and recom-mended for use with:
• SikaStabilizer to modify the viscosity of SCC.
• SikaControl AER, air-entraining admixture, to improve freeze-thaw resistance (exposure class XF1 to XF4, EN 206-1)
• Sika Separol, demoulding agent for easy formwork removal and improved finish.
• Sika Antisol, curing compound for highly efficient water retention and friendly use.


Sika® ViscoCrete® ACE 415 is not compatible with all admixtures of Sikament RB series.

Application

Application Information

Dispensing

Sika® ViscoCrete® ACE 415 is a liquid admixture to be added to the concrete during the mixing process. The best results are obtained when the admixture is added to the mixing water that is used for the concrete mix after all the other components are already in the mixer and after the addition of at least 80% of the total water.
Avoid adding the admixture to the dry aggregates. After adding Sika® ViscoCrete® ACE 415 admixture provide enough mixing time to secure a homogenous dispersion. Continue mixing and adjust the water content to obtain the required workability.

 
Consumption

Recommended Dosage

The recommended dosage rate is:

0.5 to 2.0 litres per 100 kg of the binder.
Other dosages may be used in special cases according to specific production conditions. In this case please consult our Technical Services Department.
