Sika® ViscoCrete®-90 HE is a third generation accelerated superplasticizer for the precast industry.
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.
