Affordable
Housing
By RCB Method& Structural Audit
Is R.C.C. Frame
Structure
Durable after 30
years ……? ? ?
R.C.C. Beam After 30 Years.
R.C.C. Beam & Column Crack
R.C.C. Paradi Totally Under Distress
Tree Growth in Brick Wall Bldg. Causes Damage.
Such R.C.C. Bldg. Can Collapse any time.
R.C.C. Beam,Can we Repair such Beam?
What is wrong with
R.C.C. Buildings?1) More Self Load
2) Less Cover to steel
3) Frame Structure
R.C.C.
Buildings self
Load 80 %
Live Load 20 %
So Need for
Light Materials.
By Hollow Precast
Load-bearing-Wall
By Rib Slab,
Hollow core wall,
Hollow Block
For Durability
Is Brick
Masonry Wall
Affordable-
Green- Durable?
Brick Wall ~ Block Wall
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.
Also SAVING in Time,
Mortar Joint, Plaster,
Labour, Environment,
Shuttering,
Column, Beam,
Supervision.
Need for
Green, Load Bearing ,
Affordable , Speedy

Construction Method.
R.C.C. Life…..30yrs.
R.C.B. Life........100yrs
Stone Load bearing

Knowledge &
Honesty
Green Load bearing Houses Must Be
Attractive
Economical
Eco Friendly
Proven
Simple
Speedy
Sturdy
Sustainable
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-ShutteringR.C.B. (Reinforced Concrete Block Masonry.)
Affordable Due To
Optimum Planning
Detailed Designing
Detailing of each Joint
Appropriate Technology
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
10% More Carpet Area. So Most Affordable
LESS OFFSET, MORE COMMON WALLS
1.5 BHK in 3 Lacks Beauty with Economy
TOTAL COST WITH FINISHING
For R.C.C. …….. Rs. 1000/- per Sqft.
For Aluminum Form ..Rs. 1200/- per Sqft.
For R.C.B . ………Rs. 700/- per Sqft.
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.
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.
By Reinforced Concrete Block Masonry R.C.B.

Conclusion
Presentation on Green Load Bearing Housing
Method Of Construction
Concrete block 8” X 8” X 16”
Ultimate strength = 40,000 Kg/block
Staggered Joints In Block Masonry
R.C.B. Work Under Progress
As Air is freely available
and Hollow Concrete
Block is 50% hollow, if a
structure is built by
R.C.B.
the cost of construction
is slashed down.
No Beam, No Column only RCB
13 Block Layer + Slab=15 Days.
R.C.B. Pointing From Outside
In India 300 buildings have been designed by R.C.B. method in the past 30 years by us.
In the world millions of
buildings have been built by
this established & proven
American technology in the
past 90 years.

Note : By Optimized Plan get 10% more Carpet Area.
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.
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.
R.C.B. is also Useful
For
1) Retaining Wall
2) Bridge Abutment
3) Bridge Pier
4) Highway Culverts
REMARKS 1) For Affordability Architects/Engineers/Clients
need to take a lot of efforts in Planning, Design,
Detailing & technology.
2) Client must learn to pay for the Planning,
Design and Technology in advance.
3) Affordable structure is always green.
4) Affordable does not mean cheap construction.
5) By Optimum Planning we get 10% more
Carpet Area.(Bonus to the Builders)
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.
