Abstract
ABSTRACT “BAMBOO” A GLOCAL SOLUTION Bamboo has been in wide usage since ancient times as a low-cost material for houses,bridges etc. They are the largest members of the grass family & are the fastest growing in the world. It grows approximately 4 feet in a day [in 24 hours time period]. Bamboos are of noteableeconomic & cultural significance in South Asia, South East Asia and East Asia, being use for bldg.materials as a food source & as a versatile raw product. Bamboo has higher compressive strength than wood brick / concrete & tensile strength that rivals steel & for height. Bamboo can resist forces created by high velocity wind and earthquakes. This is a substitute building material which is renewable, environment friendly & widely available, as the wood resources are diminishing & restrictions are imposed on felling the natural forests. Due to its rapid growth its adaptability to most climate conditions & due to its properties Bamboo emerges as a very suitable alternative. Industrial treated bamboos have shown great potential for production of composite Materials and components which are cost effective and can be successfully utilised for structural & non-structural applications in construction. Uses of bamboos in construction: footing, trusses, walls, scaffolding, tile roofing, reinforcement etc. Advantages : strong natural fibre, versatile material, extremely flexible, lightweight in comparison to other conventional bldg. material, sustainable & renewable ,cost effective ,construction can be done with simple tools and local artisans creating employment opportunities and empowering artisans(Glocal solution),controls soil erosion ,bamboo consumes high quantities of nitrogen so it reduces water pollution, as the urban spaces are surrounded by industries it is essential to grow bamboo alongside industrial area where it converts waste water into nutrients for its own growth , enhancement in organic farming, it is also known to desalinate sea water ,its natural waxy surface doesn’t require painting making it safe from health hazards caused by paints(they contain toxic substances) ,out of all the bldg. materials bamboo is least hazardous in terms of waste as it can be recycled & does not have disposal problems, fire resistance of bamboo is very high it can with stand temperature upto 4000 degree c., elasticity of bamboo is high. Few limitations which can be overcome easily : Bamboo is prone to insect & fungal invasion , so hazardous pesticides are used on it but not in its cultivation ,special fastening techniques are required while joining pieces of bamboo etc. The realisation that bamboo is the most potentially important non timber resource and rapid growing woody biomass, has evoked keen interest in the processing, reservation, utilisation and the promotion of bamboo has an alternative to wood and as building material. To re-establish a healthy urban environment we seek to develop policies for adaptable cities and to make the building environment more resilient to extreme weather conditions and to overcome challenges such as pollution , climate change , heat islands and resistance against health hazards ( eg : pandemic covid 19). Utilisation of bamboo as an alternative building material will be considered as Glocal solution for implementing of circulatory , urban metabolism sponge and eco-systematic approaches. The detailed case study will be presented in paper later. KEYWORDS:BAMBOOS,ECONOMICAL,VELOCITY,DESALINATE,RESILIENCE,ADAPATIBILITY,GLOCAL,URBAN-METABOLISM SPONGE, ECO-SYSTEMATIC .
