No time should elapse between the “mixing” and the “placing.”
Directions for placing must of necessity be general, and the farmer
must use his own judgment as to how to handle this part of the concrete
work, in connection with whatever particular job he has on hand. The
important thing to remember is, that the materials should not separate
in placing.
You may shovel the concrete off the board directly into the work; you
may shovel it into wheelbarrows, wheel it to position and dump, or you
may carry it to the proper place by buckets and hoisting apparatus.
