Product Data Sheet (PDS)
Sika® ViscoCrete® GL 3170 is an innovative latest generation superplasticizer based on polycarboxylic ether (PCE) polymers and is specially engineered for ready-mix concrete. Sika® ViscoCrete® GL 3170 is differentiated from conventional superplasticisers, such as those based on sulphonated melamine and naphthalene formaldehyde condensates. Sika® ViscoCrete® GL 3170 is based on a unique carboxylic ether polymer 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 stabilizes the cement particles capacity to separate and disperse. Sika® ViscoCrete® GL 3170 is suitable for use in hot and tropical climatic conditions.

POLYCARBOXYLIC ETHER SUPERPLASTICIZER FOR THE PRODUCTION OF HIGH-QUALITY READY-MIX CONCRETE AND PRECAST CONCRETE

Sika® ViscoCrete® GL 3170 is an innovative latest generation superplasticizer based on polycarboxylic ether (PCE) polymers and is specially engineered for ready-mix concrete. Sika® ViscoCrete® GL 3170 is differentiated from conventional superplasticisers, such as those based on sulphonated melamine and naphthalene formaldehyde condensates. Sika® ViscoCrete® GL 3170 is based on a unique carboxylic ether polymer 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 stabilizes the cement particles capacity to separate and disperse. Sika® ViscoCrete® GL 3170 is suitable for use in hot and tropical climatic conditions.

Sika® ViscoCrete® GL 3170 offers the following benefits:
  • Suitable for concrete mixes with low water cement ratio or high powder content without loss of workability
  • Concrete with predictable performance
  • High early compressive strength
  • High quality durable concrete with lower permeability
  • Low risk of segregation
  • Easier placing and faster strength development
  • Improved density and surface finish
  • Improved water tightness
  • 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 Sika® ViscoCrete® GL 3170 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

Compatibility

Sika® ViscoCrete® GL 3170 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 Sika® ViscoCrete® GL 3170 with the above products or other admixtures. Please consult our Sika Technical Department for further assistance.

Dispensing

Sika® ViscoCrete® GL 3170 is a ready-to-use admixture to be added to the concrete as a separate component. Optimal result is obtained if Sika® ViscoCrete® GL 3170 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.
Consumption

Recommended dosage

0.5 to 2.0 L per 100 kg of total binder. Trial mixes must be performed to establish the exact dosage rate based on required concrete perfomance.
