The paper presents research conducted on two concrete slabs reinforced with the carbon composite bars and two other concrete slabs reinforced with basalt composite bars. The carbon bars were plain, while the basalt ones were ribbed. The slabs were experimentally investigated in the flexural state of effort with the concentrated forces applied. The results are compared with the analytical solution proposed in the guide ACI 440.1R-06 of the American Concrete Institute. The calculation procedures in respect of flexure, as well as deflection, as per ACI 440.1R-06, are presented, briefly explained and discussed in the paper. Some suggestions to revise the existing procedures are offered. The authors present and discuss the following results of their experimental investigation: the ultimate capacity of the slabs, their modes of failure, deflections and the strains in reinforcement.
