1t is easy to realize that this ire
mendous time saving in concrete
work Immediately assumes great
Importance to the owner Of build
ing, as well as to the contractor
or builder.
To the owner, it menas many
days earlier income from the prop
erty-to the builder it means quick
er turnover and greater efficiency
from men and equipment.
Washington is one Of the first
cities in which this new building
material has been used for this
type Of work, and this particular
project is a striking example OF
the economy, convenience and ef-
ficiency, provided through the
speed possible in concrete con-
struction through Lumnite cement.
The owner desired to occupy this
garage on September Is, az their
lease on the other property expired
on that date. The buHuIng could
not have been completed in time
by the customary method. This
would have meant securing at least
one months storage space for vans,
with resulting confusion and Iex-
pense.
This emergency problem was sub.
mitted to Robertson and Com
pany, who stated that with this
new material they could start the
work on September 10, and de-
liver the complete structure ready
for service on Monday, September
IA, which they did, thus saving
many valuable days to the owner
1t is Of especial interest to build
ers apd the public generally, that
similar time savings can be effected
in any type of concrete construc-
ton because the cement used in
this work gives full strength twenty
efght-day concrete within twenty.
four hours.
This extraordinary high early
strength enabled the builders to
strip the forms within forty-eight
hours, from beams forty feet long
with safety-a feat in itself that is
remarkable in building practice.
The concrete for the columns,
beams and roof slabs, size of the
roof 40 feet by $50 feet, was poured
with this high early strength ce-
ment, as, was also the driveway.
While Luminite cement, the ma.
terial used on this work, is com
paratively new In this country, SINH
lar cements have been in successful
use abroad, chiefly in France, for
more than ten years past. The first
use made of such cement, because
of its rapid hardening high early
strength properties, was to pour
foundations for heavy guns during
the world war. Guns were fired
from these foundations within
twenty-four hours with no damage

neers to quickly appreciate what
mean to the building industry.
To be able to pour concrete one
day, put it in service with safety
the next, means extraordinary econ
omieS in wide range of applica-
ton.
Industrial plant repairs are made
over the weekend with no inter
ruption to plant production. Street
intersections and main trunk high
ways are repaired with no interrupt
ton to traffic.
Street railroads, traction com
panies and railroads carry on main
tenance work with no interruption
to service.
Wherever any concrete constrUc.
ton speed is desirable or emergency
makes speed a necessity, builders
will find a valuable ally in this new
cement which gives full strength
twenty eight-day concrete in twenty
four hours.
This cement is in no sense a
trick material that might give
astonishing results through the use
of some admixture. On the con
trary, it's rapid hardening and high
early strength are due to the
natural chemical action of it's chief
ingredient, aluminium ore (bauXite).
Therefore the concrete is depend
able and permanent.
The valuable feature of Lumnite
is it's simplicity in handling. Work
men who are familiar with the
methods of mixing and handling
Portland cement can, with the
knowledge thus acquired, easily sc.
cure satisfactory results with this
cement.
