Abstract
AbstractIron tailings have been extensively studied as mineral admixtures and as coarse and fine aggregates. However, few studies have been conducted on the mechanical properties of iron tailings concrete structures. Using iron tailings powder as an mineral admixture, and iron tailings gravel and sand as coarse and fine aggregates, respectively, the flexural behavior of full iron tailings concrete (FITC) beams was investigated experimentally. Compared with conventional concrete (CC) beam, we showed that the crack‐resistant, yield, and ultimate moments of FITC beams are similar to those of the concrete strain of FITC beams, which is in good agreement with the plane section assumption before cracks appear. The low elastic modulus of FITC makes the deflection of three FITC beams larger than that of a CC beam. The current design code of China is appropriate for calculating the load‐carrying capacity of FITC beam; however, the deflection calculation formula should be modified.
