|COST COMPARISON OF AAC BLOCKS:
1. Reduced number of joints and mortar savings
• An AAC block times bigger than the size of the conventional bricks which means there is less number of joints which results in lesser quantity of mortar for building. There is overall 60% reduction in use of Mortar.
2. Plastering cost savings
• Uniform shape & texture of an AAC Block gives even surface to the walls, thus there is about 35% reduction in cost of plastering.
3. Structural savings
• AAC blocks are approximately 1/5th the weight of normal concrete with resultant savings in transport, labour & construction costs.
• This dead weight reduction leads reduction in consumption of steel and cement and lesser excavation for foundations.
4. Faster ROI because of less construction time
• AAC Blocks can be sawn, drilled, nailed and route-red using normal wood working tools. This greatly increases onsite productivity and creativity. Arches, curves, mouldings and decorative features are all easily formed in the material using standard carpentry tools.
5. Increased floor space area
• Use of thinner blocks (6″ instead of 9″ exterior walls) because of its excellent water barrier & insulation properties leads to an increase in floor space area between 3-5%.
6. HVAC cost savings
• There is over all 25% savings of operation and maintenance cost in total refrigerating and air conditioning load as ACC is resistant to thermal variations.
• Reduced HVAC load .i.e. lesser capacity of transformer, DG set, cable, etc. considerably leads savings in electricity charges
