The implementation of prefabricated building methodologies and adoption of alternate building materials is increasing followed in the modern construction industry owing to numerous reasons. The foremost purpose being may be due to cost-effectiveness and environmental sustainability. Glass Fiber Reinforced Gypsum (GFRG) Panel known as Rapid walls one such load-bearing prefabricated walling system of low cost that finds application in different types of buildings. It is cent percent recyclable and is resistant to water, heat, rot and termite. Today, it is the least energy embodied building product around the globe and is eligible for Carbon Credits. The panels were originally developed in Australia in 1990 and in India by IIT Madras. At present country like India has a stockpile of 31 million tonnes of Phospho Gypsum with which 5 million 30 m2 of Rapid wall homes could be developed.

The building construction industry in India is undergoing changes with every passing days in terms of demand, supply, and technology as also environmental sustainability. The demand for the construction of houses at a faster pace and at lesser cost is currently most sought after. The houses thus built should also sustain the impacts of natural disasters like earthquake, cyclone, high tides, fire etc. which is becoming more common than ever before. The planning, designing and development of such houses often make it expensive and unaffordable for the common masses. There is also the threat of climate change being triggered by the growth of greenhouse gases in the atmosphere which a global concern. The important construction materials used for the construction of various structures till date are cement, steel, sand, stone, concrete, RCC, bricks, timber, plastics, polymers etc. The conventional method of construction with these materials produces large quantity of CO2 (about 40%) as an outcome of embodied energy consumption for cooling and heating of indoor environment and hence increases global warming. Therefore, a staunch necessity for an efficient and substitute building material that could be available at an affordable cost to build safer houses and buildings without producing a terrible effect on the environment.

The buildings should be able to sustain natural disasters like tsunami and protect humans and there assets. In contrast, the growth in agricultural and industrial activities has led to the disposal of huge quantities of wastes and bye products like fly ash from power generation by burning pulverized coal, blast furnace slag from steel and iron industry, nonferrous metal smelters, slate and marble waste, alumina red mud, etc. Lime sludge, phosphogypsum, mine tailings and red mud are the next category of waste after blast furnace slag and fly ash, available in substantial quantities. Disposal of phosphogypsum creates an enormous techno-economic problem and huge area required for its dumping. Hence by using Gypsum as a building material, challenges in the dumping of waste can be solved in an ecologically-friendly manner. Presently, there is an efficient, ecologically-friendly alternative building material available at cheap cost which has many advantages and benefits. Rapid wall technology was developed in Australia in 1990’s. The technology includes developing large-size load-bearing panels which can be utilized for roofing and walling purposes.
