8 Tips to Make Sturdy Concrete Dak Not Cracked and Curved


The robustness of a dwelling is one of the important points when building a dwelling. One of them that needs to be considered is the strength of the concrete in the building structure.

The price of building materials is quite expensive.

Therefore, not a few people are willing to suppress the material budget.

As a result, with a completely suppressed budget, the selected building construction materials tend to be of low quality.

This certainly has an impact on the strength of the building being built, for example, not concrete that is easily cracked or warped.

Currently, not concrete is widely chosen to elevate or add to the floor of a building

So that the deck construction remains strong and its durability is guaranteed, there are several things you should pay attention to.

Check out how to make a sturdy concrete deck so it doesn't crack and warp, come on!

How to prevent the concrete from cracking and warping

1. Consult with the Experts

Every construction requires experts to ensure the construction process runs properly without any problems before, during, or after.

One of the obstacles that are often experienced after the construction process is complete is that the concrete does not crack or warp due to lack of attention to its manufacture.

To avoid this, you should consult with experts to get the right direction.

For example, related to the use of reinforcing steel, the thickness of the concrete slab used, and so on.

2. Using Sufficient Reinforcing Iron

The first thing that must be considered from concrete construction is to ensure that the concrete is strong enough to withstand the tensile forces on the slab structure.

The part that serves to withstand the tensile force in the concrete construction is the reinforcing steel.

Therefore, you must ensure that the use of reinforcing steel in concrete construction is in the sufficient category, not less or more.

Because if the reinforcement used exceeds the need, it will cause the structure to be heavier and of course there will be a waste of building costs.

So, this matter needs to be consulted with experts to get the right calculation.

3. Thick enough concrete slab

In addition to the tensile force, one thing that is also very important to note is the compressive force.

Simply put, is the concrete slab used sufficient to withstand the compressive force?

Usually, concrete floor slabs are made with a thickness of at least 12 cm.

While the roof concrete slab is generally made with a minimum thickness of 8 cm.

4. Pay Attention to Building Loads

Each construction has the provisions of the load that can be supported respectively, including concrete construction.

Thus, of course there is no problem if you put a load less than the load that can be accommodated by the concrete construction.

However, it will be a problem if the load placed exceeds the capacity that the concrete construction can support.

If so, the concrete duct may crack or even warp because it is unable to withstand the load placed.

In fact, not only cracks or warps, buildings can collapse if they are put under pressure that exceeds their capabilities.

5. Concrete Quality According to Needs

Concrete construction has different qualities and each quality has its own designation.

You should really know the quality of the concrete that suits your construction needs.

The following is the quality of cast concrete based on its designation:

  1. K175: light building
  2. K225: two-story building
  3. K250: two-story heavy-duty building
  4. K300: three-story house or shop
  5. K350: three- to five-story building
  6. K400: highway construction
  7. K500: building with more than five floors

6. Slowing the Hardening of Concrete

Concrete is a construction material that hardens quickly, meaning that if it hardens too quickly, the concrete tends to crack easily.

To minimize cracks that can occur, it is necessary to decelerate the hardening of the concrete.

You can do this by sprinkling water and placing a wet cloth on the surface of the concrete.

7. Pay attention to the dismantling of the formwork so that the concrete does not bend

When making concrete, there will be a process of dismantling the formwork.

The right time to dismantle the formwork is at least 28 days after placing the concrete.

This is because the concrete material can harden completely when it is 28 days old, unless chemical substances are added to accelerate the hardening.

If there are additional chemicals, the formwork can be dismantled earlier.

8. Bending in Formwork

For the manufacture of canopies, such as ornaments on the windows of a residential house, it is better to have a curved formwork.

In the manufacturing process, the formwork is bent in the middle so that when it is disassembled the results are flat and smooth.
