Once the aggregate in it’s raw form of rock has been extracted through quarrying or mining it then needs to be crushed down and graded into different sizes for different requirements and then any unwanted matter and particles removed.
Utilisation of iron ore tailings as aggregates in concrete
tailings are segregated properly, both fine and coarse aggregates for concrete can be obtained. Therefore, if the iron ore mining companies in WA could incorporate comprehensive utilisation of the tailings in their operation, it could lead to cleaner production and sustainable development in their operation. This could have a potential of reducing both cost and environmental impacts created by
The Effect of Aggregate Properties on Concrete
The bulk density measures the volume that the graded aggregate will occupy in concrete, including the solid aggregate particles and the voids between them. Since the weight of the aggregate is dependent on the moisture content of the aggregate, a constant moisture content is required. This is achieved by using OD aggregate. Additionally, the bulk density is required for the volume method of mixture …
