Archaeological
evidence indicates that some of the very earliest large-scale buildings were in
ancient Mesopotamia; however, in many cases, the only thing that has survived is
traces of their foundations. We have
better examples of the impressive buildings constructed by the later
civilizations of Mesopotamia, Persia and the rest of the ancient Near East of
which some of them remains partially intact.
Since wood was
scarce in the area and the climate is extremely dry and hot, the most common
building material was brick formed from mud.
The bricks were easy to make as well as to use and varied from small
hand-sized bricks to large slabs used for paving. They were made from mud or clay from the
river, and then mixed with sand or chopped straw to provide additional strength. Once formed the bricks were laid in a wide
variety of elaborate and sophisticated patterns.
Although the earliest
bricks were shaped by hand, Wikipedia states by 3500 BC, “fired bricks came
into use and surviving records show a very complex division of labor into
separate tasks and trades.” The fired
bricks were used to build walls and also used with stone to make pavement. Sometime around 2700 BC, rectangular wooden
molds were introduced that produced bricks twice as long as they were wide. In addition during that same period the Mesopotamians
started producing plano-convex bricks, which have flat bottoms and sides but tops
that curve out to form a convex surface.
The plano-convex bricks were used to construct walls of buildings, which
had the convex side on the exterior wall of the structure. This type of brick lost its popularity
sometime around 2400 BC and bricks makers started to make every surface a flat
plane.
The Conco Companies are one of the
foremost suppliers of concrete services for the Western U.S. We got our start
in 1959 in the Bay Area by offering clients the best value on a broad range of
concrete services and products. Since
that time, we have taken a leading role as top concrete contractors in the
region. We have four regional offices serving California, Oregon, Nevada,
Colorado and Washington.
