benefits of concrete

Concrete has the following advantages:

  1. Concrete material is readily available.
  2. Concrete can be easily handled and molded into any desired shape.
  3. Concrete can be easily transported from the mixing site to the casting site before the initial set.
  4. Concrete can be pumped or sprayed to fill the cracks and lining of tunnels.
  5. It is possible to build any structure using steel as reinforcement; Be it lintels or huge fly-overs.
  6. The monolithic character of concrete gives it a better appearance and gives great rigidity to the structure.
  7. The property of having high compressive strength of concrete makes concrete structure more economical than steel structure.

disadvantages of concrete

Following are the disadvantages of concrete.

  1. Concrete has low tensile strength. Hence concrete needs to be strengthened to avoid cracks.
  2. In tall structures, expansion joints need to be provided if there is a large temperature difference in the area.
  3. Concrete can crack due to shrinkage, drying and expansion of moisture. Hence construction joints are provided to avoid such type of cracks.
  4. If a soluble salt is present in the concrete, it may swell when exposed to moisture.
  5. Concrete made of ordinary Portland cement tends to unify in the presence of alkali, sulphate, etc.
  6. Continuous loads develop creep in structures.
