Sika® ViscoCrete®-900 NT

3rd Generation Low-Mid Range Superplasticizer

Sika® ViscoCrete®-900 NT is a third generation low-mid range superplasticizer for concrete and mortar. It meets the requirements for superplasticizers according to ASTM C494 type G.

Sika® ViscoCrete®-900 NT acts by different mechanisms. Through surfaceabsorption and sterical separation effect on the cement particles, in parallel to
the hydration process, the following properties are obtained:
  • High water reduction (resulting in high density and strengths)
  • Excellent flowability (resulting highly reduced placing and compacting efforts)
