4.  Ar.
Laurie Baker is one who worked on cost
effective construction technique as its best.
 Baker
showed, in fact , that sustainable
technologies when adopted with care and
creativity, could lead to a unique architectural
expression.

9.  Building
Material Cost : 65 to 70 %
 Labour Cost : 65 to 70 %
( As per Central Building Research Institute
(CBRI))

10.  The
basic aspect in the choice of a material
“EMBEDDED ENERGY”

11. Stabilized Compressed Earth Blocks :Are made of mud with suitable percentage
of cement and compacted in block making
machine with no burning.
Economical, stronger, low embedded
energy and simple to manufacture

12. Reconstituted stone blocks /
Stone filler blocks
 If small pieces of stone only are
available, „reconstituted stone blocks‟
provides the best alternative masonry
block.
 Can
be used for foundations and walls.

13. Waste material content 30-40% by
volume of block.
Validated by BMTPC,
IS 12440-1985
 Better
facing

16. Foundation in comparatively hard soil
Conventional method
Better option

17.  Random
Rubble masonry with mud mortar
 Foundation
(approx)
cost : 10 to 15% of total building

18.  Arch
foundation

19.  Under
ream pile foundation

23. Bamboo reinforced surface beams in lime
concrete

24. Under reamed piles
Most economical pile

29.  Uses
425 bricks per cubic meters instead
500 bricks.
 Saves mortar.
 Thermal comfort.
 Can be left exposed, saves external
plaster.
 Tested and validated by Anna University.

32.  Bamboo
roof slab
 RCC Filler slab

33.  Ferro
cement channels
Rural house

34. Funicular shell
 Bricks/ waste stone laid in a doubly curved
profile with a shallow rise at the centre.
 Utilizes waste material
 Reduction of cement and steel

35.  Paint
is an important material used in
construction, which is
“Non recyclable”

36. •

•
•
Exposed masonry with pointed finish
Non erodible mud plaster
Lime plaster
Lime-cement combination plaster
Natural extracts as paint (cashew
oil, bee‟s wax, linseed oil)
Clay with adhesives as paint
Lime wash

37. Exposed brick masonry with flush pointed finish.

38.  Works
have done:
1. Preliminary Study on conventional materials
2.
Data collection of various non conventional
materials
3.
Study of practical applications of
nonconventional technique

39. 4.
Planning and specification for a building in
both conventional and nonconventional
system
5. Training programs and discussions
regarding relevance in COSTFORD and
Kerala State Nirmiti Kendra.

40.  Works
to be done :
1. Quantity survey of the conventional and
nonconventional residential building
2. Stabilized mud block manufacturing and
testing

41. 3. Reconstructed laterite stone blocks
manufacturing and testing
4. Energy auditing
5. Filler slab design as per grid beam theory

42.  Relevance
of the topic with respect to the
present scenario.
 What
we young engineers could promise our
society
