1.It has the advantages of continuity (absence of joints) and of fusing with other materials. 2. concrete had only a limited importance for architecture until theinvention of reinforced concrete in the 1860s. 3.Reinforced concrete was developed to add the tensile strength. It serves not only for constructing rigid frames but also for foundations, columns, walls, floors, and a limitless variety of coverings, and it does not require the addition of other structural materials. 4. Concrete is itself inexpensive. 5. The first, concrete-shell construction permits the erection of vast vaults and domes with a concrete and steel content so reduced that the thickness is comparatively less than that of an eggshell. 6.The second development, precast-concrete construction, reduces expansion and contractions. 7.Finally, prestressed concrete resists a particular load.
