| 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. | ||
