4. 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

5. 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.

6. 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.

8. 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.

9. Glass Fiber Reinforced Gypsum (GFRG) Panel, called
RAPIDWALL . It is an ideal alternative building material to
replace conventional walling system.

13. Tests carried out by SERC, CSIR Chennai ( 2002)
1. Seismic performance of Rapid wall building system
2. Investigations of behavior of Rapid wall Panel
3. Compressive strength with and without concrete in-fill
 Flexural test with Single Point Load on large panel with & without concrete infill
 Flexural Test by double point load with or without concrete infill
 Axial Compression{ Vertical Load test} on high panel with & without concrete in-
fill

14. Structural Design Manual & PACS

15. 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.

21. Design of Floor Slab
GFRG panel with reinforced concrete micro beams and screed concrete can be
used as a slab both as floor slab as well as roof slab for buildings. The basic
design philosophy as the same is that given in IS: 456-2000, corresponding to
slab behavior .
