The force feed Performance Appraisal System of fresh concrete

摘要

PROBLEM TO BE SOLVED: To accurately and adequately evaluate a pressure delivery performance of fresh concrete fed under pressure using a piping to prevent clogging of the piping before happens.SOLUTION: A pressure delivery performance evaluation system of fresh concrete evaluates a pressure delivery performance of fresh concrete and possibility of occurrence of clogging in a piping 40 by using evaluation means 30 on the basis of information acquired by measuring means 20 consisting of at least one sensor of a vibration meter, an acceleration meter, a power generation element, a piezoelectric element, a displacement meter, a strain gage, a pressure gage, a flow meter, and a speed meter with respect to the force generated when fine aggregates and coarse aggregates contained in the fresh concrete contact with the piping 40 or a cylinder 110 of a concrete pump vehicle 100.SELECTED DRAWING: Figure 1
