Affordable Housing by Green., Speedy, Sturdy R.C.B. Method. I would like to introduce one such building construction system which may change the total scenario of construction business in the near future. https://youtu.be/r9lYSMMTuIs This building system can play a great role in making Green Buildings, Eco-friendly Homes, Hotels, Slum Re-development, Transit Camps, Schools, Towers, Affordable Housing Projects. It’s called Reinforced Masonry or C.M.U., or Reinforced Concrete Block Masonry. (R.C.B.) Hope you must have heard about this. 1)R.C.C. type of construction was taught by British & we are following Beam & Column type of construction for the last hundred years or so. 2) R. C. C. building needs repairs within 15 years of construction. Not that anything is wrong with R. C. C. but there is more scope to Use inferior material & workmanship in R.C.C. & hence need for early repair. 3)Our Forts, Old buildings V. T. Station. Municipal Bldg., Palaces, Towers are generally constructed by Stone Masonry load bearing method & have stood for hundreds of years without any major repair work. 4) The same load bearing technology has been further developed in U.S.A. & is called R.C.B. which is Speedy, Sturdy, Simple, Durable, Eco-Friendly also saves up to 30% in construction cost. Called R.C.B.->Reinforced Concrete Block Masonry. 5) R.C.B. is a proven method of construction with millions of buildings being built By this way in the world. 6) about 300 buildings are Designed by R.C.B. Plannings in India, Africa and USA by us. 7)Eco-friendly as it SAVES 100% bricks,50% steel+shuttering,40% concrete,25% utility bill SAVE up to 30% in construction COST, Get up to 10% more Carpet Area by R.C.B. Planning & Design. Let's Hope Future brings us together... On Green, Durable, Affordable R.C.B. Construction Project & Structural Audit. We are RCB Planners & Designer, Structural Engineers, Structural Auditors, Technical Adviser, also Seminar Speaker & Author. Our Fee for above R.C.B. Planning & Structural Design work: about 0.5% to 10% of Construction Cost depending on size of the Project. For structural Audit Report @ 15K to 50K for Building-wing.

1. Affordable
Housing
By RCB Method
& Structural Audit

2. What is wrong with
R.C.C. Buildings?
1) More Self Load
2) Less Cover to steel
3) Frame Structure

3. R.C.C.
Buildings self
Load 80 %
Live Load 20 %

4. So Need for
Light Materials.
By Hollow Precast
Load-bearing-Wall

5. Hollow Block
Walls are
Affordable,
Speedy, Durable

6. Is Brick
Masonry Wall
Affordable-
Green- Durable?

7. Brick Wall ~ Block Wall

8. Cost of Brick ~ Block Wall
15 Brick x Rs.5/Brick:
= Rs.75/ Sq. Ft.
7.5”Block Wall Cost
= Rs. 40/ block
So SAVING=Rs.35/Sq.ft.

9. Also SAVING in Time,
Mortar Joint, Plaster,
Labor, Environment,
Shuttering,
Column, Beam,
Supervision.

10. Need for
Green, Load Bearing ,
Affordable , Speedy
Sustainable
for 100 year
Construction Method.

11. R.C.C. Life…..30yrs.
R.C.B. Life........100yrs
Stone Load bearing
Bldg. Life………1000yrs

12. Good
Construction
Needs
Knowledge &
Honesty

13. Green Load bearing Houses Must Be
 Attractive
 Economical
 Eco Friendly
 Proven
 Simple
 Speedy
 Sturdy
 Sustainable

14. While Planning the Building it is
more Appropriate To Work Out
Which is the Most Suitable
Construction Method and Plan as
per the Technology.
 R.C.C.,
 STEEL,
 PRECAST , RIB SLAB.
 Aluminum-Shuttering
R.C.B. (Reinforced Concrete Block
Masonry.)

15. Affordable Due To
 Optimum Planning
 Detailed Designing
 Detailing of each Joint
 Appropriate Technology

16. PLANNING
 More common walls
 Least number of notches
 Least wall area / Floor area ratio
 Complete detailing for each member
 Minimum number of staircase
 Least common passages
 Least foot print & loading

19. 10% More Carpet Area.
So Most Affordable
LESS OFFSET, MORE COMMON WALLS

20. 1.5 BHK in 3 Lacks Beauty with Economy

23. TOTAL COST WITH FINISHING
For R.C.C. …….. Rs. 1000/- per Sqft.
ForAluminum Form ..Rs. 1200/- per Sqft.
For R.C.B . ………Rs. 700/- per Sqft.

24. 1) R.C.C. type of construction was taught by
British & we are following Beam & Column
type of construction for the last hundred
years or so in India.
2) R. C. C. building needs repairs within 15
years of construction.
Not that anything is wrong with R. C. C. but
there is more scope to use inferior material &
workmanship in R.C.C.& hence need for
early repair.

25. 3) Our Forts, Old buildings, V. T. Station,
Municipal Bldg., Palaces, Towers are
generally constructed by Stone Masonry load
bearing method & have stood since hundreds
of years without any major repair work.
4) The same load bearing technology has been
further developed in U.S.A. which is Speedy,
Sturdy, Simple, Durable, Eco-Friendly which
also saves 30% in construction cost & is
called R.C.B./ Reinforced Masonry/ C.M.U.

26. By Reinforced Concrete Block Masonry R.C.B.
Method of Construction
Green Affordable Structures
Advantages
(Economy, Speed & Simplicity)
Architectural Features
Earthquake, Wind & Fire resistance

Total Rs 1000 Rs 700 Rs 300
Note : By Optimized Plan get 10% more Carpet Area.

94. Advantages of R.C.B. Method.
 Economy : As steel, cement, formwork, concrete & Labor
required is almost half & due to simplicity of construction &
speed, minimum saving is Rs. 300/- per sq. ft. Also by
optimum planning for R.C.B. get up to 10% more carpet
Area.
 Speed: No heavy equipment needed on site, less formwork,
less steel so construction is simple, speedier & hence
economical.
 Fire Resistant : Due to concrete block & 3.5" cover to steel,
rusting is minimized & such buildings are fire resistant too.

95. Durable: Concrete blocks are attractive, durable and have
excellent thermal, acoustic properties. No repair like R.C.C. is
needed in every fifteen years.
 Earthquake: Load bearing concrete blocks can be designed to be
wind, earthquake resistant too. Up to 22 Storied.
 Warranty: R.C.B. Method assured warrantee against heavy rain,
flood, fire, storm, earth quake & all other natural calamities for
at least 50 years.
 Architecture: Ancient type of architectural elevation is also
possible by R.C.B type of construction. Also R.C.B. is
Environmental friendly too.

96. R.C.B. is also Useful
For
1) Retaining Wall
2) Bridge Abutment
3) Bridge Pier
4) Highway Culverts

97. REMARKS
1) ForAffordabilityArchitects/Engineers/Clients
need to take a lot of efforts in Planning, Design,
Detailing, & technology.
2) TheArchitect / Engineer /Client must learn
about Planning for the Technology first.
3) Affordable structure is always green.
4)Affordable does not mean cheap construction.
5) By Optimum Planning we get 10% more
CarpetArea.(Bonus to the Builders)

98. CONCLUSIONConsidering Durability, Speed, Simplicity, 30%
Saving & 10% more Carpet Area. This Eco
Friendly R.C.B. Construction is Particularly
Suited For,
Housing,
Slum Project,
Transit Camp,
Schools & Hospital,
Hotel & Bungalow,
Industrial Projects,
Retaining Wall, Culverts etc.
