Pumped concrete is used for many different requirements and applications. A suitable concrete mix design is essential so that the concrete can be pumped without segregation and blocking of the lines. Pumped concrete offers the advantage of high concrete installation rates and great construction site flexibility.
The critical factors influencing the pumpability of the concrete are:
- Low water content to prevent segregation and bleeding
- Optimised mix design with efficient use of fines and cements
- Cement and aggregate type
- Selection of correct consistence for application
