Ren Shiman. Research on Pumpability of Ready Mixed Concrete[J]. Journal of Civil and Environmental Engineering, 1999, 21(1): 10-13. DOI: 10.11835/j.issn.1674-4764.1999.01.003.
The pumpability of ready mixed concrete is a comprehensive property. At present there is no suitable method for its evaluation. The possibility of evaluating the pumpability of ready mixed concrete by a combincd index of the slump
the slump loss and bleeding under pressure is suggested.
