Steel shape is round for better load distribution and we use steel in structures for its strength and durability.

• Round shape of steel distributes load evenly, reducing stress concentrations

• Steel has high strength-to-weight ratio, making it ideal for structures

• Steel is durable and resistant to corrosion, making it a long-lasting material

• Examples of steel structures include bridges, skyscrapers, and stadiums

Fly ash is added to improve the strength and durability of concrete.

• Fly ash is a byproduct of coal combustion and is rich in silica, alumina, and calcium oxide.

• It reacts with calcium hydroxide in the presence of water to form additional cementitious compounds, improving the strength and durability of concrete.

• It also reduces the amount of cement needed in concrete, making it more sustainable and cost-effective.

• Fly ash ...read more
