Experimental Investigation of Flexural and Impact Behaviour of Flexible FRC Slabs

The characteristics of PP and PVA FRC specimens under impact and flexural tests with totally 56 specimens were investigated in this paper. The test results indicated that effective parameters of impact were significantly increased and the specimen behavior were improved. The strength and energy absorption of rectangular specimens were respectively increased by 54 and 200% when the PVA fiber percentage was twice. Final strength PVA specimen with 3% fiber was 87% higher that of PP specimen with same fiber percentage. The impact strength of specimens reinforced with PVA fiber was three times of same specimen reinforced with PP fiber.
