The GRC screens were tested against impact test.
Normally this test was never carried out since GRC is a cladding material and it is not suppose to carry an impact. However since it was a client's requirement, this test was conducted in consultation with Glass fibber Reinforced Concrete Federation, UK (GFRC).
The test was conducted using impact weight of 5 Kg , 10 Kg and 20 Kg at different height and distance. Each impact was repeated for 6 times and GRC screen was inspected after every cycle.
|The first impact was done with 5 kg sand bag at 0.5 m and 1.2 m from base.|
|View Test - 1st Impact Cycle with 05 Kg weight & 0.5 m height & distance|
|The second impact cycle was made with 10 kg at same high and distance.|
|View Test - 2nd Impact Cycle with 10 Kg weight & 1.0 m height & distance|
|View Test - 2nd Impact Cycle with 10 Kg weight & 1.2 m height & distance|
|The third impact cycle was made with 20 Kg at similar height & distance.|
|View Test - 3rd Impact Cycle with 20 Kg weight & 0.5 m height & distance|
|View Test - 3rd Impact Cycle with 20 Kg weight & 1.4 m height & distance|
For understanding of the impact load, a 20 Kg impact at 1 m height and distance from the base will punchers 40 mm thick solid core wooden door.
All impact cycle were successfully carried out and there was no damage observed to GRC screen.
