Some Reasons for Choice of This Mate
rial in Preference to Others.
1t has been admitted by those VIII,
have studied the subject from an impair
tial standpoint that silage can be KEEP
in good condition in silo of any mate
lrial-he it concrete, stone, tile or wood
if the material selected is properly used
says the Blue Valley Bulletin. TIL,
length of time for which the silo viii
continue to fulfill in satisfactory man
ner the service required of it depends
however, upon the selection OF the mate
rial best able to combat the action Of
the elements, withstand the heavy
strains due to the silage, and furnish
la reserve for such extraordinary condi
tons as fires and cyclones.
/ The following statement OF the points
relating to use of concrete is supplied
by the Universal Portland Cement com.
pany. Concrete il permanent, wind.
proof, rodent proos and fireproof, and Is
economical in first cost and maintenance
A good concrete silo will remain indeii.
nitelv. Concrete grows stronger and
tougher with age, outlasting almost ev-
| cry other known material Reinforced
concrete is the strongest and most en-
during construction known. 1t is Sc
lected for the great engineering projects
| long bridges. massive dams. and lofty
skysenpers The development in recent
years of slender reinforced concrete
chimneys of great height shows that from
standpoint OF safety against wind re-
sistance this type of construction is I'M
equaled
Concrete silos prevent silage from dry
ing out. The idea that the juices of the
corn seep through concrete walls with
bad effect upon the latter has been dis
proved-in fact, il never has been en-
tertsined for a minute by owners of
concrete silos. The bugaboo of a con-
crete silo disintegrating through the ae-
tion OF corn acids is an absurdity. There
are hundreds OF cases where the con.
crete bases and floors of wooden silos
have been in use for long term OF years
without discoloring or disiutegrating in
the least, showing conclusively that 81.
lage acids have no effect on good con-
crete.
Two general methods Of concrete con.
struction are available for silo work
the monolithic and the concrete block,
With the former the materials are haul
ed TO the site and there mixed and placed
within forms; the latter method re-
quires that the block be made and cured
in some convenient place and later
hauled to the site to be laid up in the
wall. Each method has certain adyan-
tages and disadvantages, but the mat
ter of personal choice generally iniiu-
enee the decision 10 build either with
monolithic walls or with block. The
monolithic silo Is generally the easier
of the two for inexperienced persons to
build. and is usually little cheaper than
the block. a. il does not require the scry-
ice Of good masons or the use Of block
machine; the block silo. however. makes
the use Of forms unnecessary, produces
a wall with continuous vertical air
spaces. and slightly reduces the amount
Of materials used.
