The document describes a new technology called hypercompressed raw earth (HRE) blocks for construction. HRE blocks are an affordable, environmentally friendly alternative to burnt clay bricks. They are made by compressing local earth and have properties like high strength, insulation, and tolerance. A mechanized machine can produce 9,600 blocks per day at low cost using local resources. HRE blocks could capture market share from burnt clay bricks and provide housing solutions. The document proposes discussing the financial feasibility of a project to manufacture and sell HRE blocks using the new machine.
Change The Way We Build
- 1. CHANGE THE WAY WE BUILD Hypercompressed 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 year HRE 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 COMPARISON Properties RED BRICKS FLY ASH BRICKS HRE BLOCKS Density 1600 - 1750 kg/m³ 1700 – 1850 kg/m³ 2000 – 2300 kg/m³ Compressive 30 – 25 kg/cm² 90 – 100 kg/cm² 130 – 180 kg/cm² Strength Absorption 15 – 25% 10 – 14% 09 – 12% Dimensional Very Low High Tolerance Very High Stability Tolerance Tolerance Wastage During Up to 10% Less than 2% Less than 2% Transit Plastering 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 BLOCKS Thank You for your Valuable Time
