Wheelbarrow “Runs”
You will also have to make wheelbarrow “runs” leading from your mixing board to the spot where the concrete is to be placed. Do not use, for these runs, any old boards that are handy. Make a good run—smooth, and, if much above the ground, at least 20 inches wide. This one feature will lighten and quicken the work to a remarkable extent.
How to Mix Concrete
Having selected the proper materials and arranged the mixing board and runs, the next step is the actual process of mixing.
The proportions of materials and the nature of same for various types of work have already been [described on pages 11-13]. In following the mixing instructions here given, considerable assistance will be obtained by referring to the illustrations with which instructions are interspersed.
