MEETS STANDARD TESTS
Meritorious Qualities Of Rosen-
dale hydraulic Cement.

ROsendale hydraulic cement WHY" ~"
been manufactured for more than eighty
five years by the Consolidated Rosehuaie
Cement Company. has been adopteu ny
thousands of builders and architects In va
rious parts of this country. They point TO
the construction work done by them III
which Rosendale cement was USED 10 SUI
stantiate their assertions that the results
obtained with the cement have been UNI
formly gratifying.
Uniformity Is only one OF many speclal
claims of merit for Rosendale cement.
This cement Is constant, too, in volume
II sets under water. 1t does not WORK
short. Furthermore, 1t has great spreading
quality, always makes perfect joint ana
Is guaranteed to meet standard specitica-
tons.
BY the use of this cement the cost oil
construction is much less than II Port
land cement were used.
One barrel of Rosendale and three bar
res of sand will lay more brick, and lay
them quicker and better with no waste
numerous cement experts say IMAM one
barrel OF pure Portland and three barrels
of sand. The volume of Rosendale cement
In each barrel is about 1858 cubic feet.
Volume makes mortar not weight is Il
popular and true saying in the cement
trade circles.
koseudale hydraulic cement is safe and
sane" material for all kinds OF construc-
ton And the best and most satisfactory
results will always be obtained by specify
inc one or more Of the brands manufact-
ured by this company, which comprise
Brooklvn Bridge. Hoffman and Norton.
The Brooklyn Bridge brand is widely
known as Rosendale hydraulic cement. IL
is absolutely hydraulic, of dark. rich brown
color. finely ground, uniform, and with It
the largest possible proportion OF sand can
be used.
The entire weight of the Brooklyn Bridge
rests on concrete made from this cement
Not only has It stood the highest tests
but one need not have any fear that II VIII
be found wanting in this respect
Experience has forcefully proved that this
cement is especially adapted for heavy ma
sonrv. sewers and concrete work. Leading
architects specify and use II. Its gross
weight a barrel Is 30 pounds, and its vol
ume 3.6s cubic feet
owing to it's superior quality II was used
in the construction Of the following we'll

The number OF barrels OF Resemble hy-
draulic cement used at the Croton Aque-
duct from 1897 to 1899 was $500 The city
also used this brand Of cement IN the oul!d-
ing OF the Greene avenue sewer. Brooklyn.
and on the 5th street sewer In Williams
burg. and the Hunts Point sewer. Bronx
I'm the process OF manufacture the stone
is quarried. and. after careful selection ana
adjustment OF the quantity, is burned IN
large kilns." says the company. Then the
over or under burned rock is carefully dis
carded. and the properly burned portion
passes az once TO the crushers and Mills
where IL IL reduced 10 a fine powder. and
is then carefully screened and packed Tor

In the process OF burning before the
grinding takes place is an element OF
safety I'm that II permits the careful selec-
ton of the burned stone and the elimina-
ton Of all that is not properly burned.
This method would be entirely impossible
II the grinding took place before the burn
ing. II also frees the cement from very
large part OF the inert matter. such as
coal dust and leaves the resultant cement
durable. active. uniform and reliable
The argument is frequently advanced
that Rosendale cement does not attain
high tensile strength as quickly as Port
land. and this must be admitted 20 be a
fact But the manufacturers regard this
as an advantage rather than detrment,
I'm that II admits Of more elasticity, hence
less cracking. and also results in a steady,
unbroken and prolonged hardening entire
Is absent In Portland cement.
A number OF instances are on record
where work constructed with Rosendsle
cement many years ago has been demol-
ished and the Rosendale cement was hard
or than the stone Itself and when resort
was had TO dynamite in most instances, the
stone broke and the cement remained in
tact Such a record has not been reached
In Portland cement.
In underwater construction, particu-
larIy salt water, cement has a tendency 10
expand or swell. due probably to the effect
Of the sea water upon the free lime con-
