Expected to impact absorption energy using modified regression theory
the prediction of impact energy absorption of hybrid ferrocement slabs. Slabs were made up of self-compacting
concrete (SCC) in order to minimize the external vibration work. Slabs of size 300 X 300 mm with varying
parameters such as depth of slab (25 & 30 mm), number of layers of weld mesh (2 and 3 layers bundled), and
wrapping with Glass Fiber Reinforced Polymer sheets (GFRP) (1 and 2 layers) along with a specified proportion (0
and 0.30%) of polypropylene fibers were cast. Impact load was applied by means of a hammer of weight 3.5 kg
(34.335 N) and the initial and ultimate energy absorptions were evaluated. The variables used in the prediction
models were the varying parameters such as number of layers of GFRP sheet, area of weld mesh and height of drop.
According to the analysis, the models provide good estimation of impact energy absorption and yielded good
correlations with the data used in this study.
