New Works in Concrete.

Carnegie Library, Llandudno. ;; The photograph of building here described is probably one of the first libraries in which reinforced concrete has been adopted to any extent. It is situated in Mostyn Street, Llandudno, the

the ground floor to the gallery on the first floor, which. gives access, to the rooms on this floor. The staircase is so designed to be self-supporting; the main- reinforcement, as will be.seen, runs longitudinally, with cross bars at 2ft. centres, the whole being finished in' granolithic, with mould-: ings planted on.- ■' • ' : As mentioned, the staircase lands on a

a safe load of about 170 pounds per square foot.. The walls of the original building which stood.on the site, were used for supporting the ground floor, the slab being four inches in thickness and reinforced with' l-3in.. bars, cover being allowed for reinforcement, the surface of the floor being prepared for wood blocks. The first floors are supported on reinforced concrete

light . and pleasing effect, which would have been impossible to attain with ordinary steel construction. The reinforced concrete work was carried out by Mr. Henry Johnson & Sons, of Fontenoy Street, Liverpool; the Patent Indented Steel Bar Co., of Westminster, S.W., supplying the reinforcing steel.
