Sika® ViscoCrete®-20 HE PK – 200 LTRS DRUM | NASIR & SONS | SIKA PAKISTAN

High Range Water Reducing / Superplasticizing Concrete Admixture   USES Sika® ViscoCrete®-20 HE PK is especially suitable for the production of concrete mixes which require high early strength development, powerful water reduction and excellent flowability. Sika® ViscoCrete®-20 HE PK is mainly used for the following applications: ▪ Pre-cast concrete ▪ Fast track concrete ▪ In situ concrete requiring fast stripping time ▪ Self Compacting Concrete (SCC) CHARACTERISTICS / ADVANTAGES Sika® ViscoCrete®-20 HE PK 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; > 20%, resulting in high density, high strengths and reduced water permeability etc. ▪ Excellent plasticizing effect, resulting in improved flowability, placing and compacting behavior ▪ Reduced energy cost for steam cured pre-cast elements ▪ Especially suitable for the production of Self Compacting Concrete (SCC) ▪ ▪ Improved shrinkage and creep behavior Reduced closure times for repairs of roads and runways ▪ Sika® ViscoCrete®-20 HE PK does not contain chlorides or other ingredients which promote the corrosion of steel reinforcement. It is therefore suitable for reinforced and pre-stressed steel. APPROVALS / STANDARDS Sika® ViscoCrete®-20 HE PK follows the requirements of ASTM C494; Type F.
