GFRG

GFRG stands for Glass Fiber Reinforced Gypsum panels. The panels are manufactured in sizes of 12 m long,3m height and 124 mm (5 inch) thick thus providing more carpet area. The hollow cavities inside the panel is filled with concrete to provide more strength to the panel. GFRG panel costs 999 per sq.m. Below is an image showing GFRG panel and its internal structure.

 


 


 

Why is GFRG superior than conventional construction:


Gypsum which is a waste product of fertilizer industry is used to make the panels economical and Eco-friendly. Glass fiber is used as reinforcing agent which enhances the strength of the panels. Eventually the usage of cement is reduced.

One cement industry alone accounts for 5% increase in CO2 emission. By using GFRG panels cement usage is reduced and thereby reducing environmental pollution.

In site they are just erected using cranes. Those hollow cavities inside the panels are filled with concrete and steel. Concrete is poured in every third cavity of the panel and other cavities can be filled with waste materials like quarry dust hence its becomes more economical than conventional construction methods.


Comparison of GFRG over conventional building:





 

Factories manufacturing this GFRG panels:


FRBL-FACT RCF Cochin,Kerala

RCF Mumbai

These panels are precast in factories, transported to construction site and erected with the help of crane.

 

Test Results of GFRG:

 
 

Cons:


More space needed for crane movement

Complicated design will make it less economical

Skilled labours needed

GFRG panels should be handled with care while transportation and erection

Need specific machinery for cutting GFRG panels at site

Erection and placing of GFRG panels are a bit difficult.
 

Uses of GFRG:


As light weight load bearing wall

As partition wall

As compound wall

Cladding in industrial structures

Pitched roofing

Horizontal roofs/slabs

GFRG is a viable and tested method to construct economical homes:

This technology has been used by Australian’s since 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 storeyed model house in IIT campus 2013 which was completed in 30 days for 6.5 lakhs/flat.

 Here’s a video of GFRG demo building constructed at IIT-Madras.Total built up area of about 1981 sqft.
