Accelerating High Range Water Reducing/Superplasticising Concrete Admixture Sika® ViscoCrete®-25 MP (GB) is based on unique polycarboxylate polymers technologies. Sika® ViscoCrete®-25 MP (GB) is a liquid admixture for concrete which is used as an accelerating high range water reducer or superplasticiser. The product provides fast adsorption resulting in highly efficient dispersion and potential reduction in mixing time. It meets the requirements of BS EN 934-2. - Quick mixing
- Ideally suited for use in SCC and flowing concretes
- High water reductions resulting in higher strengths and densities
- Reduced permeability
- Fast strength development
- Improved flow
- Reduced shrinkage and creep
- Advantages in mix cost savings
- Precast energy savings
- Consistent performance of the concrete
- Chloride free
- Extended consistence retention
|
Usage - Sika® ViscoCrete®-25 MP (GB) is a unique product that is suitable for the production of ready mixed concrete as well as precast operations.
- Application that requires excellent workability and

Technical Information Specific Advice Freezing Point: +1°C Air Entrainment: Negligible, normally a minimal increase Effect on Setting: Slight extension to normal setting at 0.2% dose, normal setting up to 0.4% dose and accelerated setting at higher dosages due to its chemical nature. Effect of Overdosing: Increased workability and segregation Alkali Content: Awaiting futher testing |
Application Information Compatibility Sika® Admixtures: - All Sika admixtures can be considered
- Trial mixes should always be carried out to determine performance in-situ
Cements: - All cements including replacements
Dispensing Sika® ViscoCrete®-25 MP (GB) is added to the gauging water at the plant or added on-site into the concrete mixer. A minimum of sixty seconds mixing time is required to ensure the full effect of the product performance. |
