7.

Axial compression of wall panel 2.85m height X 2m width X 120mm thick without infill :

281.7

(140.8

kN

kN/m)

8.

Axial compression of wall panel 2.85m height X 0.775m width X 120mm thick with concrete (M20) infill :

1200

(1548

kN

kN/m)

9.

Ductility factor of Gypcrete empty panel : 4.11

10.

Earthquake resistance :
All the 6 model structures / buildings / houses tested withstood the artificial earthquake with a maximum peak ground acceleration of 0.36g satisfying the requirement of IS-1893 (Part I) 2002 for Zone V. This is equivalent to earthquake magnitude of Richter Scale 8.

IIT Madras Test Report

1.

Water absorption : 1.97% (when immersed in water for 24 hours)

2.

Rain water penetrtion : 0.57% (when subjected to simulated rain beating)

3.

Compressive strength of panel filled with Fal-G cement concrete : 11.0 N/mm2

4.

Fire resistance
:
The panel had a fire rating of 4 hours for a temperature range of 7000C to 10000C.

5.

Durability: : Proved superior quality to ensure high durability.
 a) Wetting and Drying test : No reduction in compression strength after 20 cycles of wetting and drying.
 b) Corrosion test


: Found no corrosion on steel reinforcing rod embedded with concrete filled int the cavities of the panel, when subjected to severe marine environement (Non-Corrosive)

6.

Impact test : Gypcrete building panel has high resistance against impact.  Impact resistance tremendously improved by infilling the panel with cement concrete / Fal-G cement concrete.

7.

Nailing and Pull out test : Nailing and pull out test proved that nailing and screwing can be done on the wall panel even without any infill to carry the normal weight to come on the nails and screws due to household utilities, pipe lines and electrical wirings, cloth drying ropes etc.

8.

Sound Transmission Class (STC) : Sound Transmission Test without infill found that Gypcrete panel belongs to a class of STC 40 with respect to airborne sound insulation.

9.

Young's modulus : 0.15 X 105 N/mm2

10.

Poisson's ratio : 0.15 to 0.23

11.

a) Net density of empty panel : 1139 kg/m3
b) Gross density of empty panel : 405 kg/m3
c) Density of the panel with concrete (M20) infill : 1740 kg/m3
