Determining concrete pumpability

"Experience has shown that only little changes in a concrete recipe will result in substantial effects on concrete pumpability and especially pipe system pressure. In a given situation, one may very well arrive at the conviction that some other pumping constellation than the one initially envisaged will serve its purpose better and hence a new one will be included in project preparation,“ says Dr Knut Kasten, who is in charge of development at Putzmeister’s department of application technology. But this uncertainty is now meant to be over with. “To achieve this, Putzmeister has developed a new rheometer designated "Sliding Pipe Rheometer" – in short Sliper.”
