- 85% People lives in Rural areas.
- So Residential building construction in rural areas are more in number than in urban areas.
- At present there are two types of buildings that are normally constructed in rural area
- RCC frame buildings
- Traditional mud buildings
|Type of masonry||Energy per m3||MJ||Cost / Sq.M.|
|Burnt brick masonry|
|Hollow concrete block masonry ( 10% Cement)||2141||3.31||2500|
|Soil-cement block masonry (6% Cement)||810||1.25||1100|
Normally when the people earns some money particularly those who came back after work in foreign countries construct New house of RCC frame structure as a show of prestige though more functional comfortable and cheaper house can be made from locally available materials like mud & bamboo.
Though many poor people construct their houses from the locally available materials, the houses are unhealthy and unsafe against natural disaster like Fire, Storm, Flood, Earthquake etc. One defects of these houses are excessive use of timber which effects the environment of the area. So the need in the rural areas is to improve the traditional house construction from the point of view of environment, hygiene and safety against natural disaster.
SLTD Center have developed the technology which can build hygienic and safe buildings from Mud and Bamboo which are energy efficient, cost effective and environment friendly and affordable for the people of all section of the society.
General principle for the construction of building in rural areas
A building normally has to resist three types of stress viz.:
- Compressive stress.
- Tensile stress.
- Wear and tear.
To be cost effective we have to resist all these forces by the use of local construction materials
Compressed stabilized soil block can effectively resist the compressive force but not the tensile force.
Bamboo another local building material is as strong as steel to resist tensile forces.
Cement normally a non-local building material is best to resist wear and tear. But the quantities required can be made extremely less and will have little effect in the overall cost of the building.
