4. ADVANTAGES OF FLY ASH BRICKS OVER CONVENTIONAL CLAY BRICKS
I. ECO – FRIENDLY PRODUCTS:
• FLY ASH is used as a raw material, thus RECYCLING IT.
• LESS ENERGY INTENSIVE manufacturing process.
• Recycled content helps in gaining LEED & GRIHA credits.
II. ECONOMICAL:
• Dimensional Accuracy and larger size of the hollow block therefore REDUCTION IN PLASTERING AND JOINTING
COSTS.
• REDUCTION IN LABOUR COSTS due to faster and easier construction process.
• Lighter weight reduces the dead load thus REDUCTION IN THE REINFORCEMENT REQUIRED.
• High Strength leads to MINIMUM BREAKAGE / WASTAGE during transportation.
• No chance of efflorescence therefore REDUCTION IN MAINTENANCE COSTS.
• Pre – cured products hence SAVE WATER during construction.

• Lower density and lighter weight reduces the dead load thus REDUCTION IN THE REINFORCEMENT REQUIRED.
• High Strength leads to MINIMUM BREAKAGE / WASTAGE during transportation and application.
• Excellent thermal insulation and acoustic insulation properties due to low U-value which leads to DECREASED AIR
CONDITIONING COSTS.
• No chance of efflorescence therefore REDUCTION IN MAINTENANCE COSTS.
• Reduced wall thickness therefore increase in carpet area i.e INCREASED SALEABLE / USABLE AREA.
• NO ADDITIONAL FORMWORK OR EQUIPMENT REQUIRED for reinforcing hollow block masonry.
• Pre – cured products hence SAVE WATER during construction.
