" The casings are then removed,
the cavities and other imperfections are filled in, and the wall
receives a thin facing of a finer concrete. If mouldings or other
ornament be required, they are applied to this face by the ordinary
plasterer's methods. This system finds favor in engineering
construction, and also in very simple forms of architectural work, but
with very complicated work the waste in casings is very great. Besides
this, however, the face is found sometimes to burst off, especially if
it has been applied some time after the concrete forming the body of the
wall has set, and the method of applying ornament is not economical.
[Illustration: 1.-18.]
A system of building in concrete has recently been invented by Messrs.
F. & J.P. West, of London, illustrations of which we now present. To
this system Messrs. West have given the name of "Concrete Exstruction,"
from the Latin "exstructio," which they consider to be a more
appropriate word than "constructio," as applied to concrete building in
general. In Messrs. West's system of building in concrete, instead of
employing wood casings, between which to deposit the concrete or beton,
and removing them when the beton has become hard, casings of concrete
itself are employed. These casings are not removed when the beton has
set, but they become a part of the wall and form a face to the work.
