Reducing the cost of your house by using GFRG materials
You can reduce your construction cost of 20–30% for sure by using GFRG technology.
GFRG is a viable and tested method to construct economical homes
This technology has been used by Australians since the 1990’s only as walls.
Professors from IIT Madras made research and found out this technology can be used for all structural elements such as walls, floors and roofs in a building. They have built a 2 storey model house in IIT campus 2013 which was completed in 30 days for 6.5 lakhs/flat.
What is GFRG and how is it better than conventional building?
GFRG stands for Glass fiber reinforced gypsum.These panels are manufactured using phosphogypsum which is a waste material from fertilizer industry and glass fiber used as a reinforcement.
GFRG is of 12 m in length,3 m in height and 124 mm thick thus providing more carpet area.The hollow cavities inside the panel is filled with concrete to provide more strength to the panel.Every third cavity is filled with concrete and reinforced with steel. Other cavities can be filled with a waste material such as Quarry dust or fly ash depending on the local availability to make them more economical and Eco-friendly.
Factories manufacturing this GFRG panels:
- FRBL-FACT RCF Cochin, Kerala
- RCF Mumbai
These panels are precast in factories, transported to a construction site and erected with the help of a crane.
Advantages of using GFRG:
- Economic can save up to 30% of the total cost
- Rapid construction
- NO beams or columns needed
- Cooler up to 4 degrees
- Fire resistant up to 1000 degrees
- Earthquake resistant
- Lightweight(43 kg/m2) hence low load transferred to the foundation
- Saves tonnes of cement and sand
- Reduces CO2 footprint
- Increased strength
- Greater life (Lasts upto 80 years, Conventional building lasts upto 50 years)
- Water resistant
- Less maintenance cost
- More carpet area (the Usable area inside the house)
Uses of GFRG:
- As lightweight load bearing wall
- As partition wall
- As a compound wall
- Cladding in industrial structures
- Pitched roofing
- Horizontal roofs/slabs
Certifications are given for GFRG:
- US Green building council
- Ministry of housing development in India
- Building materials and technology council
- Indian Institute of Technology-Madras
By this method, you can reduce the cost of your construction purposes or house.
