CONSIDERATION OF WORK EFFICIENCY AND MECHANICAL EFFICIENCY OF CONCRETE FORCE FEED WORK INTENDED FOR FOOTING BEAM AND SLAB

It is important to understand the content of the concrete force feed work and the pumpability beforehand to advance a concrete practice smoothly and safely when the concrete pumping method was adopted. A lot of researches on the concrete pumping method have been reported so far. However, the research that evaluates the working efficiency is extremely little. Moreover, the influence on the pumpability is not understood. In the present study, I conduct surveys of the force feed work and the mechanical efficiency of a concrete pump on actual construction fields. And, the numerical value that suits a present concrete pump industrial method is analyzed.
