Combined Superplasticiser / Viscosity Modifying Admixture for Precast Concrete Production Sika® ViscoCrete® Duo MZ-1 is a liquid high performance superplasticiser and viscosity modifying admixture providing improved rheology and robustness to high workability concretes. Sika® ViscoCrete® Duo MZ-1 is based on polycarboxylate polymers. - High-range water reductions resulting in higher strengths and densities
- Improved cohesion properties in highly fluid concrete or SCC
- Improved durability
- Improved early and ultimate strengths
- Optimal rheology properties for SCC production
- Reduced segregation and bleeding
- Reduced drying shrinkage
- Improved consistence retention
- Improved surface finish

Application Information Compatibility Sika® ViscoCrete® Duo MZ-1 may be combined with many other Sika products. Important: Always conduct trials before combining products in specific mixes and contact our Technical Service Department for information and advice about any specific combinations. Dispensing Sika® ViscoCrete® Duo MZ-1 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 is recommended. When added on site the truck mixer shall rotate its drums at maximum revolutions for at least 1 minute per m3 concrete and a minimum of 5 minutes to achieve a uniform mix. Restrictions When using Sika® ViscoCrete® Duo MZ-1 a suitable mix design has to be taken into account and local material sources shall be trialled. Sika® ViscoCrete® Duo MZ-1 shall not be added to dry cement. Excessive water addition or overdosing may cause bleeding or segregation. Support from our Technical Service Department is recommended |
