Understanding Pumped Concrete
Pumped concrete is not an ordinary mix. It's a tailor‑made combination of cement, water, fine and coarse aggregates, and flow‑enhancing additives engineered to be transported by pump rather than manual vibration.
For concrete to move freely within hoses or pipelines, the system must remain cohesive yet fluid.

Admixtures
Key characteristics of a pumpable mix include:
01
Tightly controlled water content
just enough to prevent segregation or bleeding.
02
Optimized particle grading
fine materials form a smooth internal "lubrication layer."
03
Balanced cement‑sand ratio
provides uniform viscosity and steady pressure.
04
Specialized admixtures
reduce friction, maintain cohesion, and keep the mix pumpable for hours.
