Sika® ViscoCrete® ACE 3435

(former MasterGlenium® ACE 3435)

Essential component of ZERO ENERGY SYSTEM – A new generation of high-performance
polycarboxylate ether (PCE) superplasticizers for the Precast industry

Sika® ViscoCrete® ACE 3435 (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 3435 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, as a consequence, higher strengths at very early age.
The polymer structure of Sika® ViscoCrete® ACE 3435 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 3435.

Sika® ViscoCrete® ACE 3435 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.

Usage

Sika® ViscoCrete® ACE 3435 is suitable for making precast concrete elements with highly-fluid concrete without segregation, but low water cement ratio and, consequently, high-early and final strengths. Sika® ViscoCrete® ACE 3435 may be used in combination with SikaStabilizer-110 MM for producing advanced self-compacting concrete like Smart Dynamic Concrete (SDC, latest V- type SCC), without the aid of vibration, for economic, ecological and ergonomic precast production.

System information

Compatibility

Sika® ViscoCrete® ACE 3435 is compatible and recommended for use with:
• SikaStabilizer-110 MM to modify the viscosity of SCC.
• SikaControl-100 AER, air-entraining admixture, to improve freeze-thaw resistance (exposure class XF1 to XF4, EN 206-1)
• Sika Separol 302, demoulding agent for easy formwork removal and improved finish.
• Sika Antisol, curing compound for highly efficient water retention and friendly use.
Sika® ViscoCrete® ACE 3435 is not compatible with all admixtures of Sikament RB series.

Application

Application Information

Dispensing

Sika® ViscoCrete® ACE 3435 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. The water content is adjusted to obtain the desired consistence or workability.
Optimal water reduction is obtained if the Sika® ViscoCrete® ACE 3435 is poured into the concrete mix right after the addition of the initial 80-90% of mixing water. Avoid adding the admixture to the dry aggregates.
After adding Sika® ViscoCrete® ACE 3435 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 0.3 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.
