Disadvantages of fiber reinforced concrete include its higher cost compared to plain concrete, due to the fibers. It can also be difficult to mix and place the concrete uniformly, potentially leading to a non-homogeneous material. The workability of the concrete can decrease, making it tougher to handle and apply, especially in intricate forms or detailed architectural features. There's also a limitation on the thickness of elements that can be cast, which might affect the versatility of its application in certain construction projects.
FAQs & Answers
- Why is fiber reinforced concrete more expensive than plain concrete? Fiber reinforced concrete is more costly because it requires adding fibers, which increases material expenses and sometimes complicates the mixing process.
- How does adding fibers affect the workability of concrete? Adding fibers can reduce the workability of concrete, making it harder to handle, mix, and place, especially in detailed or intricate forms.
- Are there thickness limitations when using fiber reinforced concrete? Yes, fiber reinforced concrete has limitations regarding the thickness of elements that can be cast, which may restrict its use in certain types of construction.
