- 3. INTRODUCTION Low cost housing is a new concept which deals with effective budgeting and following of the techniques which help in reducing the cost of construction through the use of locally available materials along with the improve skill and technology without sacrificing the strength, performance and life of the structure.
- 4. INFORMATION ON LOW COST HOUSING There is a huge misconception that low cost housing is suitable for only sub-standard works and they are constructed by utilizing cheap building materials of low quality. The fact is that low cost housing is done by proper management of resources. In low cost housing , building materials cost is less because we make use of the locally available materials and also the labor cost can be reduced by properly making the time schedule of our work. Cost of reduction is achieved by selection of more efficient materials or by an improved designs.

- 6. NATURAL MATERIALS BAMBOO After china, India is the second largest in bamboo production. Hence bamboo is available on large scale. India has made this grass an interesting structural materials due to its affordability, easy assembly and relatively long durability. It is eco-friendly, light weight, strong and durable and has minimal free hazard. These sheets can be used for roofing, walling, door and window shutters and other components in building construction.
- 7. EARTH Earth is the oldest building materials known to mankind. But its widespread use is hindered due to the limitations like water penetration, erosion of walls , attack of termites and high maintenance requirements.Compressed earth block is developed form of moulded earth block. It offers an economic, environment friendly masonry.
- 8. STRAW Straw is basically an agriculture by-product which comprises only of the plant stalks ( mostly cereals) after removal of grains and chaff. Straw and straw bale have a huge scope in India as it is one of the largest producers of straw bale. Straw has high potential as an alternate building material. It is also fire resistance as it does not support combustion, is thermally insulated, has sound and moisture insulation.
- 9. FIBRE CEMENT COMPOSITES Natural fibre based composites are becoming important alternatives for building materials for use in civil engineering fields due to the light weight, high strength to weight ratio, corrosion resistance. Cement fibre composites are found to have superior properties as compared to concrete blocks. This is mainly due to additional of fibres. These properties make it suitable material for use in low cost housing.
- 10. MAN-MADE MATERIALS FLY ASH Fly ash brick is a construction materials, masonry unit comprising of class C fly ash and water. Due to the high concentration of calcium oxide . These properties make fly ash bricks energy efficient, mercury pollution resistant, lower water penetration, light weight, thermal insulation and cost effective.
- 11. AEROCON PLANE Aerocon panels are the inorganic bonded sandwich panels made of two fibre reinforced cement sheets engulfing a light- weight core consisting of Portland cement, binders and a mix of silicaceous and micaceous aggregates. The use of fly ash and its substitution for timber based products makes the panels environmental friendly.
- 12. CEMENT CONCRETE HOLLOW BLOCK Cement concrete block is a recently developed masonry unit of concrete. They are cost effective and better alternative to burnt clay bricks due to their good durability, fire resistance, partial resistance to sound, thermal insulation, small dead load and high speed of construction. And as they are larger in size as a conventional clay bricks.
- 13. RICE HUSK Rice mills generate a by-product known as husk. The husk contains about 75% organic volatile matter and balance 25% weight of husk is converted into ash called as rice husk ash (RHA). The RHA produced using charcoal from husk is pozzolonic and therefore is suitable for use in block making. The RHA is highly siliceous materials so it can be used as an admixture in concrete.
- 14. FERRO-CEMENT Ferro-cement can be defined as a thin walled versatile high strength cement based composite material. It possesses the property of completely homogeneous material. It can be used for pre-cast toilet unit, water tank, cycle sheds etc. As it is pre-casted and then manufactured, it can play a major role during post disasters housing requirement which is economical and easy to build.
- 15. FUTURE SCOPE In future use of durable, attractive and environmentally responsible low cost housing materials will be a key element of any high performance building. Due to great boom in construction industry there is a growing demand for traditional building materials like steel, stone, brick and cement. Over a period of time there is a rise in shortage of building materials which increases the cost of materials. The low cost housing materials are cheaper and also provide strength to the building. Hence low cost housing is beneficial for human beings.
- 16. CONCLUSION In this study, alternate construction materials were studied and the potential of these materials to be used as alternate building material is brought out. Depending on the availability of the materials in a particular region, these materials can be selected as transportation consists of approximately 30% of total construction budget. There have been several attempts at local level to make use of bamboo, mud or natural fibers, but it still lacks scientific precisely and proper techniques to be used precisely.
