This paper presents the experimental investigations of the resistance of geopolymer
mortar slabs to impact loading. For this, specimens of size 230mmx230mmx25mm with 4 layers
of chicken mesh 2 layers of rectangular weld mesh and combination of single layer of weld mesh
and four layers of chicken mesh were cast and subjected to impact loading by drop weight test.
The results obtained show that the addition of the above mesh reinforcement has increased the
impact residual strength ratio of geopolymer ferrocement by 4-28 that of the reference plain
ferrocement mortar slab. The combination of 1 layer of weldmesh and 4 layers of chicken mesh of
geopolymer ferrocement specimens show the best performance in the test, i.e. energy absorbed,
residual impact strength ratio (Irs).It was concluded that the increase in volume fraction of
reinforcement Vr, increases the energy absorption and also residual impact strength ratio of
geopolymer ferrocement than that of ferrocement specimens.
