Concrete challenges

Since the concrete for the Sea Link project had to be pumped into the sea, it had to withstand severe corrosion by sea water and it also had to withstand challenges of nature such as temperature difference, high tide, cyclone etc. Initially, considerable difficulty was faced in pumping the concrete. At that point of time they had 1 Schwing Concrete Pump Model BP 1800 (Sl. No. 71006018) with them to execute this concreting. The Schwing Service Team checked all the parameters of the concrete and confirmed to the customer that the pump was in excellent working condition, however, the concrete specification needed to be checked for pumpability. Schwing arranged for the visit of Karl Ernst v.

Eckardstein the author of "Pumping Concrete" along with their Practical Pumping Engineer Andreas Godowski to visit the site and conveyed to the customer that without affecting the strength of the concrete some minor changes in the specification could make the concrete pumpable. The change of  the concrete mix design suggested by Schwing  experts was accepted and the pump started pumping the concrete smoothly and established the fact that the pumpability was an issue in the concrete, reinforcing the initial stand taken by Schwing. The customer understood the problem fully and went ahead purchasing another five BP 1800 Concrete Pumps from Schwing and started the concreting comfortably in this project.
