New Type Concrete That Bends
A new type of concrete known as “prestressed concrete” which, it . is ■claimed, will revolutionise present building processes, is being produced at maximum speed by British building firms. This new concrete, which will be largely used in the construction of factories, houses and offices, as well as railway sleepers, is four times stronger than normal reinforced concrete —and it bends!
This high resistance material, capable of taking strains undreamed of a few years ago, is made by stretching steel wire with a high breaking point in concrete arid then releasing'if when the concrete is set.
