Red clay bricks
Kilns around Varanasi, Chandauli and Jaunpur supply "awwal" (first-class) and second-class bricks. First-class bricks are well burnt, uniform in colour, give a ringing sound when struck together and do not absorb too much water. Ask for a sample load before booking a large order. 10,000 Red Clay Bricks Quotes in Varanasi.
Fly ash bricks
Made from fly ash, cement or lime and sand, cured properly, fly ash bricks have sharp edges and uniform size, so walls need less plaster. Ramnagar Industrial Area and Chandauli have several units. 10,000 Fly Ash Bricks Quotes in Chandauli.
AAC blocks
Autoclaved Aerated Concrete blocks are about a third of the weight of clay bricks for the same volume, which reduces load on beams and foundations. They are popular for apartments and commercial buildings. One AAC block of 600 × 200 mm covers the area of roughly 8 to 9 standard bricks. 100 Cubic Metre AAC Blocks Quotes in Varanasi.
Concrete, interlocking and paver blocks
Solid concrete blocks are a fast option for boundary walls and godowns. Interlocking bricks reduce mortar for low-cost housing. Paver blocks in 60 mm (pedestrian) or 80 mm (vehicles) thickness are used for driveways and factory yards. 2,000 Sq Ft Paver Blocks Quotes in Varanasi.
How many bricks do you need?
A useful planning figure is about 500 standard bricks per cubic metre of 9-inch brickwork including mortar, or about 50 bricks per square metre of 9-inch wall area. For AAC, divide the wall area by the face area of one block (0.12 m² for 600 × 200 mm) and add 5% for cutting. Your contractor or engineer should confirm.
Bulk ordering checklist
- Ask for landed price including loading, freight and unloading.
- Agree on breakage: what percentage of broken pieces is acceptable.
- Check size and finish on the first trolley or truck.
- Plan stacking space near the wall being built to reduce double handling.
- Keep the GST invoice for your records.

Cost comparison: think per square metre, not per piece
A red brick may cost less per piece than an AAC block, but one AAC block replaces several bricks, uses far less mortar and is quicker to lay. AAC walls also need thinner plaster. On the other hand, AAC needs a specific adhesive or a thin-bed mortar and careful handling to avoid chipped edges. The fair comparison is the total cost of a finished square metre of wall: units, mortar or adhesive, labour, plaster and wastage. Ask your contractor to price both options for one typical wall.
Seasonal supply in Purvanchal
Clay brick kilns in the region generally fire through the dry months and slow down or stop in the monsoon, so prices and availability of red bricks change with the season. Fly ash brick and AAC plants can produce year-round, which helps builders who need steady supply. If your project runs through the rains, consider booking red bricks in advance or using fly ash bricks or blocks for that phase.
Key takeaways
- Red bricks for load-bearing walls; fly ash for uniform walls with less plaster; AAC for light infill walls.
- About 500 bricks per cubic metre of 9-inch masonry.
- Compare landed price and agree breakage before you book.
