Looking for advantages and disadvantages of Air Entrained Concrete?
We have collected some solid points that will help you understand the pros and cons of Air Entrained Concrete in detail.
But first, let’s understand the topic:
What is Air Entrained Concrete?
Air Entrained Concrete is a type of concrete where tiny air bubbles are purposely mixed in. These bubbles help the concrete resist damage from freezing and thawing, and make it easier to work with. It’s like adding marshmallows to your hot chocolate to make it better!
What are the advantages and disadvantages of Air Entrained Concrete
The followings are the advantages and disadvantages of Air Entrained Concrete:
|Improves durability against freeze-thaw||Reduced strength in structure|
|Reduces bleeding and segregation||High material cost|
|Enhances workability of concrete||Difficulty in finishing|
|Resists damage from sulfate||More porous, absorbs water|
|Increases resistance to scaling||Not suitable for heavy loads|
Advantages of Air Entrained Concrete
- Improves durability against freeze-thaw – Air entrained concrete is more durable against freeze-thaw cycles. This means it can withstand extreme temperature changes without cracking or breaking.
- Reduces bleeding and segregation – It also lessens bleeding and segregation. This means the water and concrete mix better, preventing gaps and weak spots.
- Enhances workability of concrete – The workability of concrete is enhanced with air entrainment. It’s easier to place and compact, making the construction process smoother.
- Resists damage from sulfate – This type of concrete is also resistant to damage from sulfates. It can stand up to chemicals that could otherwise weaken it.
- Increases resistance to scaling – The resistance to scaling in air entrained concrete is increased. This means it’s less likely to flake or peel off over time, maintaining its strength and appearance.
Disadvantages of Air Entrained Concrete
- Reduced strength in structure – Air entrained concrete has less structural strength, making it less ideal for buildings that need to withstand high stress or strain.
- High material cost – The cost of materials for air entrained concrete is high, leading to increased overall project expenses.
- Difficulty in finishing – The finishing process for this type of concrete can be challenging, often requiring special techniques or experienced workers.
- More porous, absorbs water – Air entrained concrete is more porous, which means it tends to absorb water. This can lead to potential damage over time.
- Not suitable for heavy loads – This type of concrete is not well-suited for heavy loads, limiting its use in certain construction projects like bridges or high-rise buildings.
