| Résumé : |
Concrete is the most widely used engineering material of construction. It is comparatively inexpensive, versatile in application, strong and long lasting. Though the tensile strength of concrete is far lower than its compressive strength, the former may be buttressed with steel reinforcements. Over the last several decades this technique has greatly assisted in the expansion on the use of concrete as a material of construction. Currently, concrete is used in many buildings and structures all over the world, on walls, floors and roofs, roads, tanks, bridges, dams, pipes and many other applications. It is also used for chemical contairiments, in troughs and control basins, and as machinery mounts and structural steel supports. It is often pre-stressed and used in pre-fabricated tanks, pipes and channels, wall and roof slabs, beams, bricks and blocks. |
