Determination of the effect of lead mine waste aggregate ...

Oct 30, 2016  Table 2 shows the physical properties of aggregate classes. As seen from Table 2, the highest density was observed in barite aggregate as 3.84 g/cm 3 while the lowest value was observed as 2.52 g/cm 3 in limestone. Although, lead mine waste and limestone have the same formation, the differences between the density values are related to the presence of lead in lead mine waste.
