Of course

14,000 PSI Concrete piles work just fine.

Thanks for watching the video. I'm happy to see that you asked a great question. Sometimes, the cut-off level is much deeper compared to near-surface. The sound concrete must be above the cut-off level for the bored piles. The pile cross-section is perfectly circular in drawings, but it's not in reality. This depends on the soil profiles as well as the verticality of the boring rig. Therefore, there are variations in the concrete quantities theoretically and actually. So, in order to ensure that the sound concrete is above the cut-off level, we usually top up the concrete at the end. That's why we lift the steel casing (ensuring that the required length is embedded below the ground) and pour the concrete into the casing. At the end, we remove the steel casing, as it is temporary. I hope this explanation answers your question.

Okay I get it now. Thank you for sharing 👍🏿

You're welcome!!

Google it. There are many suppliers.

Thanks for sharing!

We are happy that a working professional watched our videos, and bring back the memories.

It's just the water. To help during coring.

Glad it was helpful!

Thank you for your comments. We will try to reduce the background music.

We understand your thoughts. However, in piling, it's tough to stagger the lapping. It's all about practicality, not about practicality. We considered these practical issues in the design of piles.

@@ProudtobeaCivilEngineer Dear we are Engineer... So don't say like this.

Do you have piling experience buddy?!?

@@ProudtobeaCivilEngineer yes.

It's all about the safety concerns. Therefore, better allow for dry before proceeding.

It's reinforcement straightner.

Hope you enjoyed the video.

Google scholar.

Thank you.

Google it.

We can help you.

How can I help you?

Thank you

Thank you for you suggestions.

Thank you.

It's not included in the project details. And the client is more concern about not to cut trees.

Nominal aggregate for our test is 10 mm

May We know what's wrong?

​@@ProudtobeaCivilEngineerwhere is thin fine sand...to flatten the surface before u put the plate..

Magnetic Particle Inspection (MPI), also known as Magnetic Particle Testing (MPT), is a non-destructive testing (NDT) method used to detect surface and near-surface discontinuities in ferromagnetic materials, such as iron, nickel, cobalt, and some of their alloys. Here's why it's particularly useful for inspecting welding: Detection of Surface and Subsurface Defects: MPI is effective in identifying both surface and just-below-the-surface discontinuities. In welding, this includes cracks, porosity, incomplete fusion, and other inconsistencies that might compromise the integrity of the weld. Immediate Results: MPI provides immediate visual results. The presence of any discontinuities is indicated by the accumulation of magnetic particles at the defect site, which can be seen directly. This immediacy aids in the quick assessment of the welding quality. Minimal Preparation Required: The surface preparation for MPI is relatively simple compared to other methods. The area needs to be clean, but extensive preparation is not necessary, making it a quick and efficient process for weld inspection. Sensitive to Small Defects: MPI is highly sensitive to small surface cracks and other discontinuities that might not be visible to the naked eye or could be missed by other NDT methods. Applicability to Complex Shapes: The method can be applied to complex geometries that are typical in welded structures. The magnetic field and the particles can conform to the shape of the object, making it versatile for inspecting welds in various configurations and positions. Cost-Effective: Compared to some other NDT methods, MPI is cost-effective, especially for the detection of surface and near-surface discontinuities. Its efficiency and speed also contribute to its cost-effectiveness. No Hazard to the Component: MPI is a non-destructive test that does not harm the material's structure or future usability, making it ideal for routine maintenance and inspection. In summary, Magnetic Particle Inspection is a crucial technique in welding to ensure the quality and integrity of welds, particularly in critical structures where strength and safety are paramount.

Hope you are new to the construction filed.

It all about the welder.

The vermiculate granules were poured into the pipe, to act as a separator in between the bentonite and the fresh concrete. This is to avoid the contamination of concrete with bentonite.

You can search in the google.

Haha it's crazy.
