Sika® Stabilizer-3199 SBS
(former MasterSuna® 3199)
Water reducing superplasticizer for the readymix industry specifically designed for use with challenging aggregates
Sika® Stabilizer-3199 SBS is an innovative superplasticizer utilizing polymers designed to improve the consistency and performance of concrete produced in readymix concrete plants.
Sika® Stabilizer-3199 SBS technology has been specifically developed to facilitate the production of concrete containing challenging aggregates, but equally suitable for day-to-day concreting with non-problematic aggregates.
Use of challenging aggregates in concrete.
The use of manufactured sand or crushed fine aggregate in concrete can pose difficulties not only to the concrete producer but also the user. Sand obtained from parent rock with active mineralogy and clays has the potential to bind water in their structure. Also, certain clays tend to absorb admixtures rendering them less effective in concrete.
Differing types and varying levels of clay contaminants make it hard to control the workability of concrete. Increasing quantities of active clays lead to higher water demand with adverse effects on the properties of concrete.
In instances where alternative aggregates cannot be sourced, Sika® Stabilizer-3199 SBS can potentially reduce effects of either manufactured and clay contaminated aggregates for easier use.
- Reduced mix costs
- Effective & compatible with manufactured sands
- Adaptable to varying levels of clay, silt and/or other dust contaminants
- Reduced need for natural sands to complement problem manufactured sand
- Improved mix efficiency
- Improves concrete appearance & rheology
- Facilitates production & consistent quality of concrete
- Preserves natural resources
- Potentially offers more robustness and ease of use with more variety aggregate sources.
