Steps Involved in Concrete Construction

Steps Involved in Concrete Construction


Concrete has been referred to as human race construction material from the nineteenth century. In recent days, the evolution of use of concrete technologies has been huge.

But the standard concrete construction technology holds a major role in worldwide construction.

The traditional concrete construction technology involves material estimating, surface preparation, building formwork, placing reinforcement, mixing, pouring, finishing and curing of concrete.

1. Materials Estimating

To keep the wonderful quality of the connected concrete work, the blending proportion of concrete ingredients ought to be measured properly and accurately.

Finally, the correct measure of the concrete ingredients are often distributed by the batching method.

Materials estimating is that the method of hard amount or proportion of materials like cement, aggregates, water, etc. area unit measured on the premise of either weight or volume to organize the concrete combine.

2. Surface Preparation

Surface or soil preparation is that the most significant side of gushing concrete. The surface uponthat the concrete is poured should be compacted and leveled. Properly getting ready the submersed helps to limit the potential for cracks within the finished concrete component.

1. Excavation

Excavation is that the opening in surface preparation for concrete activities. relying upon the kind of structure, excavation is distributed. extra a pair of inches is side within the excavation for gravel if the soil is generally wet or incorporates a high concentration of clay.

2. Leveling

Smooth out the bottom with the flat aspect of a rake in order that you've got tier surface. Fill in any low spots with soil.

3. Compaction

Tamp the bottom with a hand tamper or mechanical tamper. The tamper packs the soil down upto the requireddensity. The finished product ought to barely leave footprints once walking across it.

3. Building Formwork

Formwork in construction is that the accustomed support structures and act as molds to form structures out of concrete that is poured into the molds. Formwork are often created exploitation moulds out of steel, wood, aluminium or prefab forms.


The construction of formwork takes time and involves expenditure up to twenty to twenty fifth of the valueof the structure or maybe additional. The operation of removing the formwork is thought as husking. Reusable forms area unit referred to as panel forms and non-usable area unit referred to as stationary forms.

Good Formwork Should be;

  • Strong enough to withstand all types of dead and live loads – Rigidly constructed and efficiently propped and braced both horizontally and vertically, so as to retain its shape.
  • The joints in the formwork should be tight against leakage of cement grout.
  • Construction of formwork should permit removal of various parts in desired sequences without damage to the concrete.
  • The material of the formwork should be cheap, easily available and should be suitable for reuse.
  • The formwork should be set accurately to the desired line and levels should have plane surface.\

4. Placing of Reinforcement

Reinforcement shall be accurately placed and adequately supported before concrete is placed, and shall be secured against displacement. Reinforcement ought to be placed as shown on the inserting drawings thatindicates the quantity of bars, bar lengths, bends, and positions. the duvet is additionally necessary to assure that the steel bonds to the concrete to a tolerable degree to develop its strength.

5. Mixing of Concrete

Proper mixing of concrete ingredient is very much necessary as it affects the quality of concrete in its fresh state as well as in the hardened state. A concrete is said to be well mixed if it fulfills the following requirements.
  • The concrete mix should be uniform in color.
  • Concrete should achieve proper consistency for which it is designed.
  • The complete blending of all concrete ingredients.
  • Cement paste should cover all the surface of the aggregate.

6. Pouring of Concrete

The mixed concrete is transported to the positioning of concreting inside the initial set time.

The poring of concrete are often numerous strategies like pumping and manual transporting. the poured concrete is compacted employing a vibrator for guaranteeing correct compaction. Care should be taken to stop air pockets and guarantee a fair surface.

7. Finishing of Concrete

The most basic sort of concrete end may be a sleek surface created through the utilization of screeds and trowels. instantly when the concrete has been placed in forms, the screed is employed to level out the concrete surface.

Screeds typically contains long items of metal or wood that area unit force and pushed across the concrete surface to get rid of excess concrete and fill in gaps within the concrete surface.

8. Curing of Concrete

Curing of concrete is the last and one of the most important activities required to be taken in the process of concrete construction. Curing of concrete is the process of keeping the concrete moist to enable it to gain full strength. This last step plays a very significant role in concrete performance and needs full and minute attention.
