Q.Which of the following is/are advantages of fly ash?1.Fly ash bricks...
Advantages of Fly Ash
1. Light Weight and High Strength
Fly ash bricks are made from a combination of fly ash, sand, lime, and gypsum. One of the major advantages of using fly ash in brick production is that it makes the bricks lighter in weight compared to traditional clay bricks. This makes them easier to handle, transport, and install. Despite their lightweight, fly ash bricks offer high strength and durability, making them suitable for various construction applications.
2. Better Fill Material for Road Embankments and Concrete Roads
Fly ash has been widely used as a fill material for road embankments due to its excellent compaction properties. It helps in reducing settlement and improves the stability of the embankment. Additionally, fly ash can be used in the construction of concrete roads. It acts as a supplementary cementitious material, enhancing the strength and durability of the concrete. The use of fly ash in concrete also helps in reducing the amount of cement required, which leads to cost savings and a lower carbon footprint.
3. Settles on Leaves and Crops
Fly ash particles, when released into the air, tend to settle on the surface of leaves and crops. This deposition of fly ash can have both positive and negative effects. On one hand, it can provide some nutrients to the plants, contributing to their growth. On the other hand, excessive deposition of fly ash can obstruct the normal functioning of leaves and reduce the photosynthetic efficiency of plants. Therefore, it is important to regulate the amount of fly ash released into the atmosphere to avoid adverse effects on vegetation.
Explanation of Correct Answer
The correct answer is option 'A' (1 and 2 only) because statement 3 about fly ash settling on leaves and crops is partially correct. While it is true that fly ash can settle on leaves and crops, the overall impact of this deposition can vary depending on the concentration and duration of exposure. Therefore, statement 3 cannot be considered completely correct. However, statements 1 and 2 are valid advantages of fly ash and contribute to its widespread use in the construction industry.
