Abstract

Portable concrete pump is a tool used to pump concrete towards casting locations especially when the
locations could not be reach by truck mixers. By using portable concrete pumps, concreting process can be
finished quicker. This study begin with elaborating information about factors affecting the concreting process
such as equipment and machinery for pumping, standard procedures for placing concrete and other
requirements. The relation between productivity of portable concrete pumps and horizontal range, as well as
the height of the casting location, is derived from project observation and data collection. Further calculation
and analysis shows the regression equation for portable concrete pump productivity is obtained as Y= 1.0546–
0.00351 X
1
–0.00181X
2
with X
1
is floor height and X
2
is horizontal range. The difference in productivity
during productive time and total time that is affected by delays is 0,044 m
3
/min or the effect of delay time to
concreting productivity is 8.7% compare to productive time.
