SikaPlast® ACE 415

(former MGlenium ACE 415)

Water reducing superplasticizing admixture for precast concrete

SikaPlast® ACE 415 consists of a range of innovative superplasticizers based on newly developed polycarboxylate ether polymers. The particular molecular configuration of SikaPlast® 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, as a consequence, higher strengths at very early age.
The polymer structure of SikaPlast® 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 SikaPlast® ACE 415.
Suitable for use in hot and tropical climatic conditions.

SikaPlast® ACE 415 offer the following benefits for the precast concrete industry:
  • Production of highly flowable, robust self-compacting concrete having a low water cement ratio.
  • Enhanced robustness and consistency in concrete quality with low stickiness.
  • Elimination of heat curing.
  • Improved surface appearance.
  • Durable precast concrete elements as per EN 206-1.
  • Optimization of the curing cycles by reducing curing time or curing temperature.
  • Increased productivity.
  • SikaPlast® ACE 415 may be used in combination with Sika® Stabilizer. The technology produces advanced self-compacting concrete, without the aid of vibration. For economic, ecological and ergonomic ready-mix concrete production.

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using SikaPlast® ACE 415 in concrete.
Refer to relevant standards.
Fresh concrete must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian.

Application

Application Information

Dispensing

SikaPlast® 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. The water content is adjusted to obtain the desired consistence or workability. Avoid adding the admixture to the dry aggregates. After adding SikaPlast® ACE 415 admixture provide enough mixing time to secure a homogenous dispersion. Continue mixing and adjust the water content to obtain the required workability.

Compatibility

SikaPlast® ACE 415 is suitable for mixes containing all types of cement and supplementary cementitious materials such as: Microsilica (Silica Fume), Fly Ash (PFA), GGBS (Ground Granulated Blast Furnace Slag) and the following Sika® products:

  • SikaPump®
  • Sika® FerroGard®
  • SikaFume®
  • SikaFiber®
  • Sika® Aer
  • Sika® Stabilizer
  • SikaControl®

We recommend to perform trial mixes to establish the required performance when combining SikaPlast® ACE 415 with the above products or other admixtures. Please consult our Sika Technical Department.
Consumption

Recommended dosage

0.5 - 2.0 % by weight of binder
Other dosages by weight of binder can be used depending on the mix design, raw materials, climatic conditions and concrete requirements. Trial mixes must be performed to establish the exact dosage rate required.
