- Concrete paving blocks
- Masonry blocks
- Hollow-core slabs
- Concrete roof tiles
- Kerbstones
- Landscaping elements
- Semi-dry manufactured concrete products
Benefits
- Optimised concrete mix design
- Higher early strength
- Shorter production cycle times
- Shorter curing times
- Improved production efficiency
- Maintains or improves product appearance
- Optimises the hydration potential of cement
- Suitable for hot and tropical climatic conditions
Application guidance
SikaPaver-726 is supplied as a ready-to-use liquid admixture and is added during the concrete mixing process. For best results, add SikaPaver-726 after all other concrete components are in the mixer and after at least 80% of the total mixing water has been added. Adjust the remaining water to achieve the required consistency or workability. The optimum dosage depends on the mix design, raw materials, climatic conditions and required concrete performance. Trial mixes must be carried out to establish the exact dosage. Adequate compaction of both base and face concrete is essential to achieve the required performance of semi-dry manufactured concrete elements.
Coverage
Recommended dosage: 0.4–1.2% by weight of binder. Dosages outside this range may be used depending on the mix design, raw materials, climatic conditions and concrete requirements. Trial mixes must establish the exact dosage.
