摘要: Abstract An experimental study comprising laboratory and real scale tests was carried out to evaluate the usefulness of several pumping, early age hardened parameters for pumped Self-Compacting Concrete (SCC) quality control. Two SCC, with fly ash limestone filler, were tested. Pumpability controlled online by real-time measuring pumping pressure discharge rate. Temperature, capillary pressure, dimensional stability P-wave ultrasonic pulse transmission (UPV) measured simultaneously monitor microstructure evolution at (EA). UPV (P- S-waves) also used as non-destructive testing method Pumping reduced compressive strength between 12 16% changed air permeability, although did not modify porosity accessible water. These Quality Control Parameters (QCP) showed their ability detect changes on material’s EA performance. Accordingly, they can be establish acceptance limits identify potential issues arising from undesired in properties.
