Eco-Friendly and Rapid Houses

There have been numerous efforts to build rapid houses across the country. Most innovative among them is the method created by IIT Madras students, who have built rapid, eco-friendly houses by using ‘Glass Fibre Reinforced Gypsum’ (GFRG) panels. They have successfully built a housing unit, which was constructed within a month using pre-fabricated GFRG panels made from waste gypsum.

The fertilizer industry produces around 2,000 tonnes of gypsum everyday in the form of waste, which is dumped over a large area. This waste is re-processed by calcining it into gypsum plaster, which forms the raw material for gypsum panels, which are manufactured in Mumbai by Rapidwall Building Systems, Australia.

The manufacture of these boards is done in three stages: Firstly, the gypsum plaster is spread on a special table, on which glass fibers are poured. Secondly, another layer of gypsum plaster is poured by using specific equipment to leave a gap between the two layers and then it is left for hardening for 30 minutes. In the third stage, these boards are removed and dried faster in a special chamber. These panels are cut into required sizes using a computerized machine at at the factory and brought to the construction site to used for all parts of the building, right from walls to staircases to roofs. Trenches are first dug at the construction site and the bottom surface is plastered with cement.

The foundation is made of conventional fly ash bricks and plinth beams are cast on it. The entire gap is filled with soil and then plastered with cement. This process takes 11 days to complete.
