1.2 Advantages And Disadvantages of




          concrete in construction industry.





          • Disadvantages of concrete



                 – Low tensile strength and cracks easily



                 – Shrinks on drying and expands on wetting will lead to

                     cracks


                 – Expands and contracts with the changes in


                     temperature


                 – Creep (prestressed concrete production)


                 – Liable to disintegrate by alkali and sulphate attack



                 – Lack of ductility inherent in concrete to be used

                     earthquake resistant design.
