types

• low cost housing in villages
• low cost housing in cities

low cost housing in villages

• mud houses
• mortar houses

mortar houses

• fly ash bricks
• lime moratar bricks
• normal bricks
• cement mortar bricks

low cost housing in cities

• rcc
• aluform
• prestressed
• precast

rcc
tests were done on red bricks flyash bricks and fly ash blocks

aluform
worked out the costs and compared to rcc. it becomes more costly and does not fulfill the requirements

Normal bricks are Rs. 7 of 6 inches. They are a good option if a kiln is available near by.

Fly ash bricks are also a good option but transportation cost is added. It's a rupee cheaper than normal bricks.

This block was made using lime and sand and then compressed using a simple rammer. The block was allowed to dry in sunlight for 3 days.

The strength of the block was going to be 7 MPA.
It is quite suitable for a single storey house

Cement mortar brick was also made and its strength was around 8.3 MPA.

rcc structure
we can use normal bricks fly ash bricks or autoclaved fly ash blocks for walls but blocks are more preferred.

Size of the brick. 22*15*8 cm
Comparison between fly ash block and fly ash brick was done.
Type Weight/cubic metre.

Fly ash brick. 1245.79
Fly ash block. -864.19
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
381.79

Fly ash brick price = Rs.1893/cubic metre
Fly ash block price= Rs. 5825/cubic metre

So even if we save in per cubic metre cost in bricks, May that be fly ash or red, the weight of
these bricks is much more than the fly ash autoclaved block. Hence the block saves in steel and
is much more economical as it reduces the dead weight on the building.

Conclusion
If at all the shortage of housing is to be wiped out then it is necessary to move away from conventional approaches and adopt locally available material which can save upto Rs. 40 per sq.ft. Thus fresh and new innovative ideas at management level should be quickly executed.
