文摘
- •
Study of mortars with iron ore tailings (IOT): physical-mechanical properties.
- •
IOT present higher density than natural aggregates due to the iron concentration.
- •
Mortars with IOT showed mechanical properties fitter to brick laying than regular ones.
- •
Replacement up to 20% of lime by IOT granted satisfactory properties for coating.
- •
IOT morphology and voids required more mixing water to obtain plasticity in mortars.
