Sika® ViscoCrete®-3110 PK

Concrete Admixture for High Flow/Self-Consolidated Concrete

Sika® ViscoCrete®-3110 PK is a polycarboxylate based superplasticizer developed particularly for use in ready mixed concrete to give extended slump retention and high strength development of normal grade concrete mixes. Sika® ViscoCrete®-3110 PK is suitable for use in concrete mixes        incorporating pozzolanic materials such as GGBS, PFA and microsilica. Suitable for use in hot and tropical climatic conditions.

Sika® ViscoCrete®-3110 PK acts by surface absorption on the cement particles producing steric hindrance as well as electrostatic repulsion between cement particles which results in higher dispersion, flow and retention. Sika® ViscoCrete®-3110 PK provides the following beneficial properties:
  • Powerful plasticising action
  • Production of workable concrete at low W/P   ratio
  • Improved shrinkage and creep characteristics
  • Excellent flowability resulting in minimal placing and compacting efforts
  • Slower rate of carbonation ingress
  • Cost effective, structurally economic
  • Higher ultimate strengths allows greater flexibility for engineers to design
  • Reduces surface defects so improving aesthetic appearance.
  • Durable concrete
  • Does not contain chlorides or other steel corrosion promoting ingredients

Usage

  • Production of site mixed and ready-mix            concrete
  • During hot weather production of concrete with extended transportation or placing times
  • Concrete with low water / cement ratio
  • Concrete placement in congested steel               reinforcement
  • Self-compacting concrete
  • Slim elements requiring a high standard of       surface finish
  • High performance / high strength concrete

Technical Information

Concreting Guidance

The standard rules of good concreting practice for production and placing must be observed when using Sika® ViscoCrete®-3110 PK 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®-3110 PK may be combined with all types of Portland cement (OPC and SRC), concretes containing pozzolanic materials such as;

GGBS, PFA, micro-silica and the following Sika products:

▪SikaPump®

▪Sika® FerroGard®-901

▪SikaFume®-92 D PK

▪SikaFiber®

▪Sika® AER PK

▪Sika® Stabilizer

▪Sika®-1 WT

We recommend to perform trial mixes to establish the required performance when combining Sika® ViscoCrete®-3110 PK with the above products or other admixtures. Please consult our Sika Technical Department.

 

Dispensing

Sika® ViscoCrete®-3110 PK is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant. Do not add Sika® ViscoCrete®-3110 PK directly to the dry mix. For optimum utilization of its high water reduction property we recommend thorough mixing at a minimal wet mixing time of 60 seconds. The addition of the remaining gauging water (to fine tune concrete consistency) may only be started after two-thirds of the wet mixing time to avoid surplus water in the concrete.
Consumption

Recommended Dosage

For soft plastic concrete 0.2 – 0.4% by weight of binder. For flowing and self-compacting concrete 0.4 – 1.5% by weight of binder. Higher dosages up to 1.7 % 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.
Application steps

CLEANING OF TOOLS

Clean all tools & application equipment with water immediately after use.
