Stresses in Diagonal
Tension Reinforcement
No
entirely satisfactory and consistent theory of the action of web reinforcement
of concrete beams has yet been devised and very likely never will be. The usual
methods as here presented are frankly approximate, little more than empirical
rules that experience shows give safe and reasonably economical results. The
center stirrup of the three shown in Fig. 28 may be assumed to carry all, or
part, of the vertical component of diagonal tension acting in the distance m
along the 45 degree line of potential rupture. The horizontal opening of the
crack is prevented by the longitudinal steel which may be considered, accordingly,
to carry the horizontal component of the inclined tension. To rate the stirrup
as carrying the entire vertical load is determined by the strength of both the
steel reinforcing being used and the concrete. The development of the American
Portland Cement industry during the past decade has been one of the marvels of
the age, and while Portland Cement Concrete has come to be recognized as the
ideal building material for heavy work, comparatively little attention has been
given to its use in the small construction about the home and on the farm. That
active interest, however, is taken in this important subject by the
suburbanite, the villager, and the farmer, is evidenced by the large number of
letters of inquiry received by the agricultural and technical journals. During
the past few years the price of lumber has advanced to almost prohibitive
figures, and it is therefore only natural that a substitute material which
affords the advantages of moderate cost, durability, and beauty should: be
looked upon with favor. It is not our purpose to enlarge upon the uses for
which Portland Cement is now considered standard, but rather to direct
attention to the economy of supplanting wood, brick, and cut stone in divers
ways by the more durable, attractive, and sanitary
In
the following pages we shall endeavor to point out, in language free from
technical terms, some of the uses for which Portland Cement Concrete is
especially adapted.

making two or CIRCULAR more forms, place them at equal distances apart, and put
on these boards are called concrete forms. The quantity of tools will, of
course, vary with the size of TOOLS AND the gang of men. The following schedule
is based on a small APPARATUS gang of two or three men, making concrete by
hand: Concrete construction dates back to the time of the Romans, who secured
good results from a mixture of slaked lime, volcanic dust, sand and broken
stone. Even this combination, crude in comparison with Portland Cement
Concrete, produced an artificial stone which has stood the test of nearly two
thousand years, as evidenced by many works in Rome which are to-day in a
perfect state of preservation. "Portland Cement" is an invention of
modern times—its universal use the matter of a quarter of a century. The honor
of its discovery belongs to Joseph Aspdin, of Leeds,
England, who took out a patent in 1824 for the manufacture of "Portland
Cement," so called because of its resemblance, in color, to a then popular
limestone quarried on the Island of Portland. Manufacture was begun in 1825,
but progress was slow until about 1850, when, through improved methods and
general recognition of its merits as a building material, commercial success
was assured. About this time the manufacture of Portland cement was taken up in
earnest by the French and Germans, and, by reason of their more scientific
efforts, both the method of manufacture and quality of the finished product was
greatly improved. Portland cement was first brought to the United States in
1865. It was first manufactured in this country in 1872, but not until 1896 did
the annual domestic production reach the million-barrel mark.
