Can steel fiber reinforced concrete be pumped?

Can steel fiber reinforced concrete be pumped?

Yes, but expect a 0.4” to 1.2” slump loss through the hose depending on the steel fiber dose rate, ambient temperatures and hose length. A midrange water reducing agent (MrWr) is commonly used to enhance workability and ease of flow through pump lines. High-range water reducers (HrWr) may be required in some cases. typically, a 4” diameter hose is required.
