Conventional building materials are :
Energy intense
Demand is growing
Materials like river sand & water is scarce
Cost’s spiraling up
Increases CO2 emission & impact on environment
&
Construction is time consuming
Therefore , there is a need for an alternative building materials & fast construction methods for housing

RATIONALE
Pospho-gypsum is produced as byproducts of chemical , fertilizer
industries and due to its limited usage , this waste is becoming an
environmental problem.
The Rapidflow Calciner and Rapidwall Technology can help to
overcome these problems by turning waste into plaster and the
plaster into homes that are environmentally friendly, non-
polluting, energy efficient and aesthetically pleasing.

GFRG / RAPIDWALL - A REVOLUTIONARY BUILDING MATERIAL
GFRG/ Rapid wall is load bearing pre-fabricated walling panel. This
is suitable for rapid mass scale building construction was originally developed and used since 1990 in Australia.
GFRG/ Rapid wall is manufactured using Gypsum as a core
material , which is generated as by product in the process of manufacturing fertilizers
GFRG/ Rapid wall is manufactured at RCF , Mumbai and FRBL ,
Kochi. GFRG/ Rapid wall is suitable for load-bearing applications and as
well as hybrid Construction in multi-storey buildings.

reinforced by glass rovings
Micro-strand glass roving role
• Rapidwall panels are 12m
long , 2.85m high and
0.124m thick.
• Made from Gypsum, Glass
Rowing, and Special
Chemicals.
• Made from Australian
Technology
GFRG / Rapid wall Panel
Tensile strength of glass roving (single filament) is 3100-3800 Mpa (tensile strength of glass roving is much higher than even that of steel used for concrete reinforcement which is maximum @ 500 Mpa) Elastic Modulus of glass roving is 76-78 Gpa This provide very high load bearing capability to the panel making into a composite material.

Applications • In apartment buildings, some up to 14 storey's, concrete filled Rapidwall
panels have been used very successfully in load-bearing construction to support combined lateral and vertical loads and to support vertical loads only.
Load-bearing walls in multi-storey construction
• Rapidwall panels, either unfilled or concrete filled, can be used to support domestic structures. Unfilled Rapidwall can be used to support domestic structures up to two storey's providing the suspended floor is constructed from timber.
Individual Dwelling Construction
• Unfilled 100 millimeter Rapidwall (current panels are 124 mm) will provide an FRL of 180/120/60 and concrete filled Rapidwall an FRL of 240/240/240.
Walls that require high fire rating
• Insulation filled Rapidwall panels have been successfully used in cottage construction as structural roof elements over which battened roof sheeting is placed.
Roof panels
• When used as permanent-formwork for suspended concrete slabs, services such as electrical or plumbing can be carried in the cells, noise attenuation between floors is improved and a finished plaster ceiling is obtained.
Permanent formwork for suspended slabs
• Rapidwall has been used extensively for domestic fencing providing a high
quality finish to both neighboring properties. Uniquely Rapidwall can be placed directly in trenches and sand filled to provide solid foundation free fences up to two meters high.
