Content
Until the early 20th century, concrete was mixed on the job site and transported from the cement mixer to the formwork, either in wheelbarrows or in buckets lifted by cranes. This required a lot of time and labor. In 1927, the German engineers Max Giese and Fritz Hull came upon the idea of pumping concrete through pipes.

Neville Barns discusses the real-time challenges faced by pump operators on site. 
It is important to have all concrete mixes specified as "pumpable" prior to any concrete pours. There are mixes that do not pump at all or cause the pump lines to clog. Possible pumping issues may result from:
  • Pumping rate
  • Line diameter
  • Line length
  • Horizontal and vertical distances
  • Configuration, including reducing sections
  • The vertical rise
  • The number and severity of bends
  • The amount of flexible hose used in the line
