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.

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%

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
