In order to study the flexural capacity of reinforced RC bidirectional simply supported slab of high-performance cement Ferro cement laminate (HPFL), made experiments on 1 contrasting plate and 4 HPFL reinforcement plates with the same parameters, and simulated with ANASYS software. The experimental result and the simulated result both indicated that compared with the non reinforcement plate, the reinforcing plate flexural bearing capacity and stiffness were greatly improved, and crack resistance performance of reinforcement plate was obviously improved. It was confirmed that the HPF-reinforced RC plate was capable of improving the plate flexural performance. The plastic hinge line theory was adopted to analyze and calculate the bearing capacity of the reinforcement plates, and the calculating result was highly similar to the test and numerical simulation results.
