Cost of construction going up and paucity of skilled labour are resulting in high outgo for infrastructure. Besides environmental factors are also making people to look for alternative materials that will reduce energy consumption or result in lesser utilisation of precious natural resources.
Pre-fabricated glass-fibre reinforced gypsum (GFRG) walls provide an alternative that allows faster construction saving time, using eco-friendly material and at a lesser cost as well for luxury houses. GFRG material is used in construction of a house in Bhimili mandal.
Mohan Mandava, founder-director of Ameya World School at Sangivalasa in Bhimili mandal has been searching for alternative materials to reduce the huge infrastructure time & cost and also to use eco friendly materials. Even during the construction of the school campus in 2007, PSG slag cement, which few preferred at that time, was used, he recalled. Also fly ash bricks were used instead of clay bricks that are made using top soil.
When he came to know about GFRG, his friend tax consultant and builder Tammina Srinivas who was planning to construct a house for his parents at T. Nagarapalem in Bhimili mandal readily agreed for its use, says Mr. Mohan who was associated with the planning, designing and construction of the house.
GFRG is made by using gypsum, a waste produced while manufacturing fertilizers. It piles up at fertilizer plants and its disposal is a big problem, he says. The material for the pre-fab walls is made by reinforcing it with glass fiber. The Kochi unit makes 12-metre-long panels with 3 metres of height.
The Fertilizers and Chemicals Limited (FACT), Travancore, and Rashtriya Chemicals and Fertilizers formed the joint venture to produce pre-fab walls at Kochi.
