Construction of concrete stairs includes steps like designing, preparing foundation, building formwork, positioning of reinforcement steel bars, concreting, finishing and curing. Construction of concrete stairs is often a trial that needs an engineer to study each of the aspects and style it plus a skilled labour to construct it.

Steps for Construction of Concrete Stairs
The followings are the steps associated with construction of concrete stairs,

1. Designing of Concrete Stairs
Designing of stairs requires through understanding of design aspects and site study. The factors that influence design for stairs are height with the floor, width from the stairs, risers depth, thread width, thickness with the stairs, angle in the stairs, load placed onto the steps and many other aspects which uses a qualified engineer to create an ideal stairs.

2. Foundation and Support for Concrete Stairs
The inspiration on what the concrete stairs rest shall be properly constructed so that the tons of the stairs are transferred in to ground successfully also to resist the movement of stairs.

When the plinth beam to construct is found at the start of the steps, then the reinforcement steels bars might be connected to them that can transfer the masses. If no plinth beam is located, then a small concrete foundation or size stone masonry is made.

To compliment the stairs at the very top which restricts the movement of stairs is generally implemented to the roof beam or slab.

3. Building the Form-work for Concrete Stairs
The main step when building concrete stairs is to use an effective formwork. The angle of flight, dimensions of thread and riser can be properly checked. Usually while creating a stairs that come with wall, the queue of flight , thread and risers are marked on the wall for correct fixing of shuttering or formwork.

It's has to be no less than 2” thick, regarding offer the weight from the concrete. The entire structure with the form, should be supported by 4?4 posts. The wooden boards are widely-used to produce the steps and therefore are fastened with several screws to the lateral structure of the formwork.



Use a spirit level, about ensure that the form is level and plumb, if you want to obtain a neat look. The form of the concrete stairs should be attached to the ceiling.
These steel reinforcement bars are placed inside the formwork with at least 25 mm spacing which is tied together.

5. Pouring of Concrete for Concrete Stairs
Pouring of concrete into the formworks is started from your below part to above. The concrete mix plays a huge role in strength and durability of stairs. Standard mix utilized for stairs are 3 parts cement, 2 parts sand, 4 parts gravel and water.

It is recommended make use of a concrete vibrator while pouring the concrete to fully fill the gaps from the stairs and to avoid the honeycomb formation.

4. Steel Reinforcement for Concrete Stairs
The concrete steps can be reinforced with steel bars to be able it carries the masses coming upon the stairs and transfer these phones the floor. The amount of steel bars and size of the bars will be calculated by way of a structural engineers dependant on the masses beginning the stairs.

These steel reinforcement bars are placed within the formwork with minimum of 25 mm spacing and is tied together.

5. Pouring of Concrete for Concrete Stairs
Pouring of concrete in to the formworks begins from the below part to above. The concrete mix plays a huge role in durability and strength of stairs. Standard mix used for stairs are 3 parts cement, 2 parts sand, 4 parts gravel and water.

It is recommended work with a concrete vibrator while pouring the concrete to fully fill the gaps with the stairs also to avoid the honeycomb formation.

The project is usually to be through with great care and patience , just like any sudden movements can disturb the alignment of the formworks and even collapse the formwork. It will always be recommended to pour the concrete ceiling and stairs from the 24 hour, regarding produce a strong bond between these factors.

6. Removal of Formwork
The stairs requires at least A three week period to dry out completely, and so the elimination of formwork would be to done only after 21days. Over these A 3 week period proper curing is to completed to prevents the cracks in stairs due to thermal expansion.

After the Twenty-one days, the formwork is taken off with a hammer as well as a crowbar. Assist patience, as to avoid damaging the concrete or even the edges in the stairs.

7. Finishing of Concrete Stairs
After the formwork is taken away, the stairs can be carried out in a number of ways as per the element the use. It could you need to be finished using trowel or float to provide concrete finish, cement tiles, granite may be installed for much better appearance. Even carpet or wood may also be used in order to complete the stairs.
