AVOIDABLE   DANGERS  IN   REINFORCED   CON¬
CRETE MILL CONSTRUCTION.

IN a recent discussion of the possible dangers incident to the
use of reinforced concrete in mill construction, Mr, Leonard
C. Wason, president of the Aberthaw Construction Co., of Eos-
ton, was led to speak from his experience. He at once showed
that practically all of the possible dangers are avoidable; that
they are entailed by incorrect design or poor workmanship,
and that there is nothing inherently dangerous in the use of
reinforced concrete. So far as strength and structural featurea
go, it has few limitations, discrimination in use being controlled
principally by its adaptability. Recognizing the common im¬
pression that almost anybody can mix and place concrete, Mr.
Wason emphasized the vital importance of employing skilled
men:

First-—Because the reinforcement might otherwise be im¬
properly placed, perhaps too high in the beams and girders, or
in the top of the floor slabs, thereby introducing serious sources
of weakness. To the ignorant laborer such misplacement would
mean nothing; in fact it being a not uncommon practice to
spread the concrete out over the forms and lay out the bars
on top. Under sucli conditions the laborer is more apt to spread
the concrete thick than thin, because if very thin the stone in
the concrete interferes in the spreading.

Second-—Because of the errors which may arise through tho
selection of the wrong size of bars for reinforcement. It is a
simple matter for a man to overlook the difference of an eighth
of an inch in diameter, which in small bars may make a differ¬
ence of 50 per cent, or more in the strength. Sometimes the
wrong number of bars may be used.

Third-^Beeause an unskilled or careless foreman may
erroneously read his plans- Sometimes he may set the bars at
right angles to the correct position- In columns, the bars are
usually placed near the surface to avoid flexure; but It la
easier to place the concrete if they are nearer the middle. If
nearer the middle, however, the (lexurd-is not taken care of and
the tie between the floor and column is not so rigid.

Mr. Wason referred to some of the failures of reinforced
concrete which have been reported, and stated that although
usually sworn to as caused by the drawing of the form work
too soon, the fact is usually that the failure really has been
due to Improper setting of the steel and to careless placing o(
the concrete- In a failure which occurred in Philadelphia
about two years ago, sawdust and shavings were found in th«
columns where they had fallen before the concrete was placed.
The effect was lo reduce the cross sectional area of the column*
by fully 50 per cent.

The difference in strength between tamped and untamped
concrete was shown to be 30 per cent., due largely to the fact
that under the latter conditions it does not flow around the
reinforcement. As a consequence voids are formed. It waa
also pointed out that when the concrete is mixed dry it doea
not properly grip the bars. Mr. Wason asserted that It has
been pretty conclusively proven by disinterested engineers who
have carefuly examined such failures that they were due to
carelessness on the part of the contractor and his workmen,
and that none of them were due to incorrect principles of
design.

In a word the danger lies in hidden defects—which once
covered from sight are revealed only by disaster.
 

EQUITABLE PLANS.—The deathless rumor that the Equit¬
able Life Insurance Society will erect a new building at 120
Broadway was revived during the week by a statement that an
alteration has been made in the plans, and that when the so¬
ciety has disposed in some manner of the stock of the Mercan¬
tile Trust Company and the Mercantile Safe Deposit Company
something "definite" will be done about a new building. It is
also now said that the revised plan when made public will
show a building having but 32 stories, which will be erected in
sections, the Nassau st side first. The fact that the safe de¬
posit company held a long term lease on the basement has
been one of the ascribed causes for deferring the erection of
the new building. On the valuation of $12,000,000 the present
structure does not make a fair return and neither is it big
enough for the society's business, as some of the Equitable's de¬
partments occupy rented quarters in the vicinity.
