Compressive and flexural strengths of concrete with iron

The concrete density up to 2459 kg/M obtained in this study. The result indicated that compressive strength increase with the age of sample. The flexural strength and compressive strength of concrete, with iron ore decreased as a percentage increase in the replacement of iron ore.

Fracture probability modelling of impact-loaded iron ore

2017-4-1  During a test, an iron ore pellet was loaded between two platens at a speed of 4.8 µm/s until fracture occurred. From the tests, the load deformation behaviour and fracture data of the iron ore pellet samples were evaluated. In this work, the dynamic testing of iron ore pellet was carried out using the split Hopkinson pressure bar (SHPB) assembly.

Utilization of iron ore tailings as fine aggregate in

2014-1-15  Natural sand and iron ore tailings were used as aggregates. The natural sand was originally excavated from the lower reaches of Yangtze River and had an apparent density of 2.63 g/cm 3.The tailings were obtained from the local iron and steel industry and had an apparent density of 2.62 g/cm 3.The chemical composition of the tailings is shown in Table 1.

Study on the Utilization of Iron Tailings in Ultra-High

In this paper iron tailing sand (TS) are used as aggerate to develop ultra high-performance concrete (UHPC). The mix proportion of UHPC is designed and TS were added by 25%, 50%, 75% and 100% (wt.%, i.e., weight percentage) to replace natural river sand. Firstly, the influence of TS on the slurry behavior was carried out. The experimental result indicates that with the continuously increasing
