Testing pumpability of concrete using Sliding … – ScienceDirect
The inadequacy of current equipment and the scarcity of sound methodologies give birth to the demand for dedicated, portable, yet reliable testing equipment for the quantitative estimation of pumping pressure and the determination of concrete’s pumpability. A new concrete testing equipment, Sliding Pipe Rheometer (Sliper) has been developed by Putzmeister to solve the above-mentioned problems.
