Sika® ViscoCrete®-1200 NT MY

3rd generation superplasticizer

Sika® ViscoCrete®-1200 NT MY is a third generation superplasticizer for concrete and mortar.

Sika® ViscoCrete®-1200 NT MY acts by different mechanisms. Through surface absorption and sterical separation effect on the cement particles, in parallel to the hydration process, the following properties are obtained:
  • Strong self compacting behaviour, therefore suitable for the production of self compacting concrete (S.C.C.)
  • Extremely high water reduction (resulting in high density and strengths)
  • Excellent flowability (resulting in highly reduced placing- and compacting efforts)
  • Improved shrinkage- and creep behaviour
  • Reduced rate of carbonation of the concrete
Sika® ViscoCrete®-1200 NT MY does not contain chloride or other steel corrosion promoting ingredients. It may therefore be used without any restrictions for reinforced- and prestressed- concrete construction.

Usage

Sika® ViscoCrete®-1200 NT MY is suitable for the production of site mixed as well as ready-mix concrete. It is compatible when used with cement replacements, PFA, GGBS and microsilica. Sika® ViscoCrete®-1200 NT MY is used for concrete with extended transportation - or placing time. Sika® ViscoCrete®-1200 NT MY facilitates extreme water reduction, excellent flow properties, optimal cohesion and highest self compaction behaviour. Sika® ViscoCrete®-1200 NT MY is used for the following types of concrete:
  • Self compacting concrete (S.C.C.)
  • Hot weather concrete and concrete with extended transportation - or placing time
  • Concrete with highest water reduction (up to 30 %)
  • High strength concrete C60 – C100+
High water reduction and excellent flowability have a positive influence on the above mentioned applications.

Application Information

Compatibility

Sika® ViscoCrete®-1200 NT MY may be combined with the following Sika products: SikaPump®, SikaRapid®, Sika® FerroGard®-901 MY, SikaFume®.

Pre-trials are recommended if combinations with the above products are being made. Please consult our technical service.

DISPENSING

Sika® ViscoCrete®-1200 NT MY is added to the gauging water or simultaneously with it poured into the concrete mixer. For optimum utilisation of the high water reduction we recommend thorough mixing at a minimal wet mixing of 60 seconds.

The addition of the remaining gauging water - to fine tune concrete consistency - may only be started after 2/3 of the wet mixing time, to avoid surplus water in the concrete.
Consumption

Recommended Dosage

For soft plastic concrete

0.25–1.0 % by weight of cementitious

For flowing and self compacting concrete (S.C.C.)

1.0–2.5 % by weight of cementitious
