Bricks can be classified as clay bricks, concrete bricks, and fly ash bricks. Concrete can be classified as normal concrete, high-strength concrete, and lightweight concrete.

• Types of bricks: clay bricks, concrete bricks, fly ash bricks

• Types of concrete: normal concrete, high-strength concrete, lightweight concrete

Bricks: Burnt clay bricks, Fly ash bricks. Concrete: Plain concrete, Reinforced concrete, Prestressed concrete.

• Bricks: Burnt clay bricks are made by burning clay in a kiln. Fly ash bricks are made from fly ash, lime, and gypsum.

• Concrete: Plain concrete is a mixture of cement, sand, and aggregate. Reinforced concrete has steel bars embedded in it for added strength. Prestressed concrete is pre-compressed to reduce crack...read more

• Deep foundations: piles, drilled piers, caissons

• Special foundations: raft foundations, pile caps, underpinning

• Used based on soil conditions, building loads, and site constraints

Types of columns include reinforced concrete columns, steel columns, composite columns, and wooden columns.

• Reinforced concrete columns are commonly used in building construction for their strength and durability.

• Steel columns are often used in industrial structures due to their high load-bearing capacity.

• Composite columns combine materials like steel and concrete for optimal performance.

Types of slabs include one-way slab, two-way slab, flat slab, and ribbed slab, each used for different purposes.

• One-way slab: used for small spans and supported on two opposite sides.

• Two-way slab: used for larger spans and supported on all four sides.

• Flat slab: used for heavy loads and provides more flexibility in design.

• Ribbed slab: used for longer spans and reduces the weight of the slab.
