SikaPlast® GL 119

(former MGlenium 119)

Polycarboxylic ether-based superplasticizer for the production of high-quality ready-mix
concrete

SikaPlast® GL 119 is part of a range of latest generation superplasticizers engineered for ready-mix concrete.
SikaPlast® GL 119 is based on unique polymers with long lateral chains. This greatly improves cement dispersion. At the start of the mixing process the same electrostatic dispersion occurs but the presence of the lateral chains, linked to the polymer backbone, generate a steric hindrance which stabilises the cement particles capacity to separate and disperse.
This mechanism provides flowable concrete with greatly reduced water demand.

SikaPlast® GL 119 provides the following beneficial properties:
  • Substantial improvement in workability without increased water
  • Low risk of segregation
  • Improved density and surface finish
  • Improved water tightness
  • Excellent solution for continuous concrete casting of deep elements
  • Does not contain chlorides or other steel corrosion promoting ingredients

Technical Information

Concreting Guidance

The standard rules of good concreting practice for production and placing must be observed when using SikaPlast® GL 119 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® GL 119 is a ready-to-use admixture to be added to the concrete as a separate component. Optimal result is obtained if SikaPlast® GL 119 is poured into the concrete mix right after the addition of the first 80% of the mixing water, i.e. when all solids are wetted. Avoid adding the admixture to the dry aggregates.

Compatibility

SikaPlast® GL 119 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 that trial mixes be performed to establish the required performance when combining SikaPlast® GL 119 with the above products or other admixtures. Please consult our Sika Technical Department.

 
Consumption

Recommended Dosage

0.8 - 2.5 % 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.
