Sika® ViscoCrete®-10

HWR- High Range Water Reducer 

Sika® ViscoCrete®-10 is a third generation superplasticiser for concrete and mortar. It meets the requirements for   high range water reducing superplasticisers according to AS1478.1-2000.

Sika® ViscoCrete®-10 is a powerful superplasticiser which acts through several different   mechanisms including surface adsorption and sterical effects separating the cementitious binder particles. The following advantageous properties are achieved:
  • High water reduction, resulting in high density, high strength and reduced permeability
  • Superior plasticising effect, resulting in improved flow, placing and compaction characteristics
  • Reduced shrinkage during curing and reduced creep when hardened
Sika® ViscoCrete®-10 does not contain chlorides or any other ingredients which promote the corrosion of steel. It is therefore suitable for use in reinforced and pre-stressed concrete structures.

Usage

Sika® ViscoCrete®-10 is especially suitable for concrete mixes with extended transportation times and extended workability requirements, high water reduction and improved flow characteristics. Sika® ViscoCrete®-10 is mainly used for the following applications:
  • Concrete with ultra high water reduction (up to 30%)
  • High performance concrete
  • Concrete in hot weather and with extended transportation and workability requirements

Technical Information

Concreting guidance

Laboratory trials shall be carried out before concreting on site, especially when using a new mix design or producing new concrete components.

Fresh concrete must be cured properly and curing applied as early as possible.

Application

Application Information

Dispensing

Sika® ViscoCrete®-10 is added to the gauging water or added with it into the concrete mixer.

To take advantage of the high water reduction, a wet mixing time, which is depending on the mixing conditions and mixer performance, of at least 60 seconds per cubic metre after the admixture addition is recommended.

Sika® ViscoCrete®-10 shall not be added to dry cement.

Compatibility

Sika® ViscoCrete® can be used in conjunction with all the admixtures manufactured by Sika Australia PTY Limited with the exclusion of Sikament ® NN. All admixtures must be added separately.

For additional information, please contact Sika technical personnel.
Consumption

Recommended dosage

Recommended dosage for concrete:
250 ml to 2000 ml per 100 kg of total cementitious material.

Optimum dosage should be determined by site trials.
