Sika® ViscoCrete® MP-5000

High Range Water-Reducing and Retarding Admixture with enhanced workability retention

Sika® ViscoCrete® MP-5000 is a polycarboxylate based superplasticizer developed particularly for use in ready mixed concrete to give extended slump retention and high strength development of high specification grade concrete mixes.
Sika® ViscoCrete® MP-5000 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® MP-5000 acts by surface absorption on the cement particles producing steric hindrance and electrostatic repulsion between cement particles which results in higher dispersion, flow and retention.
Sika® ViscoCrete® MP-5000 provides the following beneficial properties:
  • Powerful plasticising action
  • Production of workable concrete at low w/b 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
  • Reduced surface defects so improving aesthetic appearance
  • Durable concrete
  • Does not contain chlorides or other steel corrosion promoting ingredients

Usage

Sika® ViscoCrete® MP-5000 is mainly used for the following applications:
  • Production of site mixed and ready-mix concrete
  • During hot weather production of concrete with extended transportation or placing times
  • Concrete requiring retained workability
  • Concrete with low water binder ratio
  • Concrete placing in congested steel reinforcement
  • Depending on dosage rate used; high flow and self-compacting concrete (SCC)
  • 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® MP-5000 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® MP-5000 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®, SikaFiber®, Sika Aer®, Sika® Stabilizer, Sika®-1 WT, Sika® WT-10
We recommend to perform trial mixes to establish the required performance when combining Sika® ViscoCrete® MP-5000 with the above products or other admixtures. Please consult our Sika Technical Department.

Dispensing

Sika® ViscoCrete® MP-5000 is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant.
Do not add Sika® ViscoCrete® MP-5000 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

0.8 - 2.0 % by weight of binder
Higher 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.
