Flexural Moment Capacity Evaluation of Reinforced RPC Two-way Slabs
This paper presents calculations to determine the flexural moment capacity of Reactive Powder Concrete (RPC) two-way slabs depending on three models from previous studies (Model 1, Model 2, and Model 3). The outcomes of these calculations were compared with experimental results to tempt the accuracy and the applicability of the adopted theoretical models. The experimental program included testing three simply supported RPC two-way slabs of 1000 mm length, 1000 mm width, and 70 mm thickness. The tested specimens were of identical properties except their steel fibers volume ratios (0.5 %, 1 %, and 1.5 %). It was found out that the first model (Model 1) is the most suitable among the three models, where its outcomes were very close to the corresponding experimental data, while Model 2 was underestimated the failure load, and Model 3 was overestimated it by large differences, where the maximum difference between the theoretical and experimental failure load according to the mentioned three models was 3.4%, 48.2%, and 87.2% respectively.
