56.25 CMU/day and you calculated 9 days. Then
multiply 56.25 times 9 which equals 506 block. There
is a two block difference which is not much in this
example, but it could be if you were estimating
thousands of square feet of CMU.
Brick masonry is masonry construction in which
units of baked clay or shale of uniform size, small
enough to be placed with one hand, are laid in courses
with mortar joints to form walls. Bricks are kiln-baked
from various clay and shale mixtures. The chemical
and physical characteristics of the ingredients vary
considerably. These characteristics and the kiln
temperatures combine to produce brick in a variety of
colors and hardness. In some regions, individual pits
yield clay or shale which, when ground and moistened,
can be formed and baked into durable brick. In other
regions, clay or shale from several pits must be mixed.
To lay brick efficiently and effectively, you must
be familiar with the terms that identify the position of
masonry units in a wall. The following list, which is
referenced to figure 4-1, provides some of the basic
terms you will encounter:
Course One of several continuous, horizontal
layers (or rows) of masonry units bonded
Wythe The wythe is a continuous vertical
section of a wall, one masonry unit thick. This is
sometimes called a tier.
