With Sika® Technologies it is possible to produce fresh concrete with the required consistence and good internal cohesion. Friction and resistance in pipes is reduced, helping maintain pumping pressure at a more constant and lower level. Sika technology for pumped concrete allows the realisation of the most demanding and challenging concrete requirements on construction sites. The successful construction of many structures is based on Sika® Technology, in combination with our experience in the development of the best mix designs.
Sika® ViscoCrete® to reduce water contents, improve rheology characteristics and cement hydration efficiency.
Sika® ViscoFlow® to enhance workability time, increase transportation and placement time.
Sika® Stabiliser® to improve the internal cohesion properties of fresh concrete.

The Benefits of Pumped Concrete
The improved internal cohesion of fresh concrete and the reduced friction during pumping created by Sika® ViscoCrete® and Sika® Stabiliser® technologies will give significant advantages.Increasing the performance of the concreting process will make the concrete more cost efficient with the following additional benefits:
- Faster and consistent placingOptimised cost of mix design with efficient use of fines/cements
- Enables use of poorer aggregates and grading (i.e. recycled aggregates)Increased quality and durability
- Less blockages
- Less labour
- Longer pumping distances can be achieved
- Reduced wear on pumping equipment
- Taller heights can be reached in the construction of superstructures
- Improved concrete surfaces
