Product Data Sheet (PDS)
Sika® ViscoCrete® GL 3171 is an innovative latest generation superplasticizers based on polycarboxylic ether (PCE) polymers and is specially engineered for ready-mix and precast concrete to achieve extended workability retention without affecting the early strength of the concrete. Sika® ViscoCrete® GL 3171 is differentiated from conventional superplasticizer, such as those based on sulphonated naphthalene formaldehyde condensate. Sika® ViscoCrete® GL 3171 is based on unique carboxylic ether 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. Suitable for use in hot and tropical climatic conditions.

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

Sika® ViscoCrete® GL 3171 is an innovative latest generation superplasticizers based on polycarboxylic ether (PCE) polymers and is specially engineered for  ready-mix and precast concrete to achieve extended workability retention without affecting the early strength of the concrete.
Sika® ViscoCrete® GL 3171 is differentiated from conventional superplasticizer, such as those based on sulphonated naphthalene formaldehyde condensate.
Sika® ViscoCrete® GL 3171 is based on unique  carboxylic ether 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. Suitable for use in hot and tropical climatic conditions.

Sika® ViscoCrete® GL 3171 offers the following benefits for: The ready-mix producer:
  • Capability of delivering high performance concrete
  • Production of a concrete with low water cement ratio without loss of workability
  • Single product for many application requirements
The contractor / applicator:
  • Easier placing and faster strength development
  • Improved density and concrete surfaces
The engineer:
  • Predictable performance
  • High quality durable concrete

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using Sika® ViscoCrete® GL 3171 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 3171 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 3070 with the above products or other admixtures. Please consult our Sika Technical Department for further assistance.

Dispensing

Sika® ViscoCrete® GL 3171 is a ready-to-use admixture to be added to the concrete as a separate component. Optimal result is obtained if Sika® ViscoCrete® GL 3171 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 kgs of total binder. Trial mixes must be performed to establish the exact dosage rate required.
