Ini alasan Saya tidak menggunakan DAK LANTAI HEBEL

Summary

This video script delves into the growing use of *dak hebel*, a lightweight concrete panel, in construction. The speaker highlights its affordability, ease of installation, and strength, which has made it increasingly popular. However, concerns are raised about the lack of clear sources behind the method and the safety risks associated with using *dak hebel*, especially when tested through methods like stepping on it. The transcript also compares *dak hebel* to traditional materials, such as *panel beton*, and emphasizes the importance of considering both cost and safety when opting for this construction method.

Takeaways

• 😀 Hebel is gaining popularity as a cost-effective, practical, and fast solution for floor and roof slabs in construction.
• 😀 There are online videos showing people testing the strength of Hebel by stomping on it, raising questions about the reliability of such informal tests.
• 😀 Some viewers have expressed concerns that testing the strength of Hebel by walking on it might not be a safe method and could pose risks to residents.
• 😀 Hebel is often compared to other lightweight concrete panels (panel beton), which have slightly higher compressive strength but are less commonly available.
• 😀 Panel beton has a compressive strength of 6.2 N/mm², significantly higher than the 4.0 N/mm² of Hebel blocks, making the two materials different in terms of durability and performance.
• 😀 The cost of using Hebel for flooring or roofing is slightly cheaper than traditional concrete, but the cost difference is not very significant when factoring in additional materials like reinforcement steel.
• 😀 There are risks associated with Hebel's porosity, as water can seep through it and potentially weaken the steel reinforcement if it is not properly sealed or protected.
• 😀 Hebel installation typically requires fewer workers, with some methods claiming that just two people are sufficient to complete the job quickly.
• 😀 While Hebel's strength is often touted as sufficient for certain applications, some experts warn that it may not be suitable for more load-bearing structures like ceilings or floors under heavy use.
• 😀 The origin of the idea to use Hebel for flooring and roofing is unclear, as the theory and method of application seem to have spread through online videos and informal channels, with no clear academic or industrial source.

Q & A

What is dak hebel, and why is it considered unique in construction?

Dak hebel is a lightweight concrete slab used in construction for flooring and roofing. It is considered unique due to its cost-effectiveness, ease of installation, and the relatively new approach it offers in comparison to traditional concrete methods.

What are the main claims made about dak hebel in the video?

The video claims that dak hebel is strong, cost-effective, and easy to install. It is also described as being practical, fast, and lightweight, requiring only two people for installation. However, there are safety concerns regarding its long-term durability.

Why is the testing method of dak hebel by stepping on it questioned in the video?

The method of testing dak hebel by stepping on it is questioned because it does not accurately measure the material's overall strength or safety. Critics argue that this method is not a reliable indicator of the material’s ability to withstand real-life usage, particularly in load-bearing applications.

What are some of the safety concerns raised about dak hebel?

Some safety concerns include the risk of dak hebel failing under stress, as indicated by negative comments on the testing videos. Critics argue that improper installation and lack of proper reinforcement could make dak hebel unsafe, particularly if moisture exposure leads to corrosion of the reinforcement metal.

What is the difference between dak hebel and panel beton (concrete panels)?

Panel beton (concrete panels) is a material specifically designed for structural applications with higher compressive strength, making it more suitable for load-bearing purposes. Dak hebel, while cheaper and easier to install, has a lower compressive strength and is generally not recommended for heavy-duty use.

How does dak hebel compare to traditional materials like Bondek in terms of cost?

Dak hebel is cheaper than traditional materials like Bondek in terms of initial costs, but the price difference is not significant enough to make it a clear winner when considering long-term safety and durability. Bondek, being more proven, may offer better value in the long run despite the slightly higher price.

What is the concern about the waterproofing in dak hebel installations?

The concern with dak hebel installations is that they often use a plaster layer instead of concrete for finishing. Plaster is less effective at preventing water infiltration, which can lead to moisture seepage into the dak hebel, potentially weakening the structure over time.

What does the speaker think about the material's strength and its testing by foot pressure?

The speaker doubts the validity of using foot pressure as a test for dak hebel’s strength. While stepping on it might show that the material doesn’t crack easily, this method does not account for the potential long-term weaknesses of dak hebel, such as its ability to bear heavy loads.

What role does metal reinforcement play in dak hebel, and why is it a concern?

Metal reinforcement is essential in providing structural strength to dak hebel. However, if the metal reinforcement is exposed to moisture or humidity (for example, due to poor installation or plaster finishing), it can rust, weakening the overall structure and posing a safety risk.

What is the recommended alternative to dak hebel for use in flooring or roofing according to the speaker?

The speaker recommends using panel beton (concrete panels) or other more traditional materials that are designed for load-bearing applications. These materials are structurally stronger, more durable, and safer compared to dak hebel, especially when used for critical parts of a building.
