Sika® ViscoCrete®-90 HE as a powerful superplasticizer acts by different mechanisms. Through surface adsorption and sterical effects separating the binder particles the following properties are achieved:  

• Pronounced increase in the early strength development, resulting in very economic stripping times for pre-cast and in situ concrete
• Extremely powerful water reduction, resulting in high density, high strengths and reduced water permeability etc.
• Excellent plasticizing effect, resulting in improved flowability, placing and compacting behavior

Sika® ViscoCrete®-90 HE does not contain chlorides or other ingredients which promote the corrosion of steel reinforcement. It is therefore suitable for reinforced and pre-stressed steel.
