Transcript

  • 1. CHANGE THE WAY WE BUILDHypercompressed Raw Earth Blocks (HRE) Manufacturing
  • 2. HRE BLOCK TECHNOLOGY Offers a cost effective, environmentally sound masonry system Product – Hypercompressed Raw Earth (HRE) Blocks Applications  Walling  Vertical Load Bearing Walls  Partition and Interior Walls  Arched Openings  Corbels etc
  • 3. HRE BLOCKS Features  Low Energy and Emissions (Environmentally Friendly – No Pollution, Requires Little or No Water)  Uniform Size  High Strength  Thermal Insulation  Versatile  Cost Effective  Manufactured and made Available Round the Year
  • 4. HRE BLOCKS Manufactured by  Hypercompressing by Natural Drying  Use of ALL Surface or Deep Raw Earth / Industrial Mineral Refuse mixed with a stabilizer (maximum of 3% of the total content)  Use of Hydraulic machine under a pressure of about 200 kg/cm² applied to the product Product  Size – 9 cm x 14 cm x 29 cm  Compressive Strength – about 130 kg/cm² Raw Material  Earth Soil – Available at Construction Site
  • 5. HRE BLOCKS – DEMAND ESTIMATES Burned Clay Bricks Market  Potential of 460 billion bricks every year  Growth Rate by 3-5% every year Even at a very conservative 3% market share, the Demand would be for 13.8 billion bricks per yearHRE Blocks can be used for Almost All the Applications of Burnt Clay Bricks
  • 6. ALTERNATIVE TO BURNED CLAY BRICKS –FLYASH BRICKS However, manufacturing of Flyash Bricks  Need 50 cents to 1 acre Land  If it has to be Profitable, it needs to be within 100 kms from a Thermal Plan  Flyash Availability is a concern because of Demand from Cement Industry (about 15% is mixed with the Cement)  Flyash Quota needs to be approved, SSI Certificate required (if in Tamil Nadu)  Availability of Lime and Sand / Stone Dust
  • 7. ANOTHER ALTERNATIVE TO BURNT CLAY BRICKS- HOLLOW & CEMENT CONCRETE BLOCKS Raw Materials  Cement  Stone Chips  Stone Dust  Sand Today, Cement (INR 240 to INR 250 per bag) and Sand (INR 50 + Taxes per cft) prices have sky-rocketed and unlikely to be reduced in the short-run, hence with inputs costs increasing the Hollow and Cement Concrete Blocks may not be feasible if Project Costs have to remain constant Needs 24 hours Drying and further 2 to 3 weeks of Curing before they can be used
  • 8. HRE BLOCKS – A QUICK COMPARISONProperties RED BRICKS FLY ASH BRICKS HRE BLOCKSDensity 1600 - 1750 kg/m³ 1700 – 1850 kg/m³ 2000 – 2300 kg/m³Compressive 30 – 25 kg/cm² 90 – 100 kg/cm² 130 – 180 kg/cm²StrengthAbsorption 15 – 25% 10 – 14% 09 – 12%Dimensional Very Low High Tolerance Very HighStability Tolerance ToleranceWastage During Up to 10% Less than 2% Less than 2%TransitPlastering Thickness vary on Even on both sides Even on both sides both sides of the wall
  • 9. HRE BLOCKS - APPLICATIONS Low-cost Housing in Rural and Urban Areas Middle Income Housing in Urban Areas Affordable Housing in Rural and Urban Areas
  • 10. HRE BLOCKS Given that there is DEMAND for HRE Blocks, the Manufacturing Process would be  Manual  Mechanized To be Cost Effective and Produce Volumes of the HRE Blocks the process has to be mechanized Further slides talk about the Mechanized HRE Blocks Manufacturing Machine
  • 11. HRE BLOCKS MANUFACTURING MACHINE Process  Uses Local and Available Resources at the Site of Construction  Double-sided Compression allowing  Perfect Homogeneity of the HRE Block  Steadiness of Mechanical Characteristics  Produces  High Density Product guaranteeing  Immediate Handling and Erection at Fresh State  Reduce in Bearing-wall Thickness but still offering Block Strengths of about 130 kg/cm² at Stabilized state  Perfect Finished Look to the wall  Precise Dimensions  Increased Thermal Insulation  Greater Stability  Mass Blocks without any Production Rejection
  • 12. HRE BLOCKS MANUFACTURING MACHINE Standard Output Capacity – 600 Blocks / Hour If deployed in 2 shifts of 8 hours each per day, can produce  600 nos. x 8 hours x 2 shifts  i.e. 9,600 HRE Blocks per day  Resultingin Overall Construction of about 250 – 260 m² / day
  • 13. HRE BLOCKS MANUFACTURING MACHINE–POTENTIAL BUYERS Group housing Companies  Can Benefit from the use of Available Local Material (Excavated Earth) at the site of Construction  Safety against Increase Costs of Construction Material Contractors  Avail of the Advantage of Mobility of the Equipment and Save on Transportation Cost by producing bricks at the site of Construction Owners of Local Clay Brick / Wire Cut Brick Kilns  As business diversification into production of HRE Blocks
  • 14. HRE BLOCKS – POSSIBLE SOURCE OF REVENUE HRE Block Manufacturing Machine  Outright Sale  Rentals  1 Personnel deployed to Man and Operate the Machine  Operational Support & Costs to be borne by the Renting Party  Investments  Security Deposit – INR 500,000  INR 0.40 to INR 0.50 per HRE Block as per Manufacturing Capacity of the Machine used Sale of HRE Blocks in the Market Sale of Carbon Credits generated through use of Environmental Safe Technology
  • 15. HRE BLOCKS Can we meet and discuss the Financial feasibility Of Taking up the Project?
  • 16. HRE BLOCKSThank You for your Valuable Time
