Solidification/stabilisation of metals contaminated industrial soil from former Zn smelter in Celje, Slovenia, using cement as a hydraulic binder

Impact of Dust Filter Installation in Ironworks and Construction on Brownfield Area on the Toxic Metal Concentration in Street and House Dust (Celje, Slovenia)

“…The observed elements for the calculation of the statistics are Co, Cr, Fe, Mn, Mo, W and Zn. Regarding the brownfield site in Celje, past data (Romih et al 2010;Voglar and Leštan 2010) show that this is very heterogeneous material and the concentrations of toxic metals vary drastically. The material in the brownfield is contaminated with As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Pb and Zn.…”

“…Remains of the bricks, demolition waste, tar, pyrometallurgical waste and other debris have been placed here. Its thickness varies between 0.5 and 5 m. Concentrations of metals are very heterogeneous and can reach extreme values (Voglar and Leštan 2010). The most problematic elements are Cd (max.…”

Assessment of the operating windows of a combined solidification/stabilization and granulation treatment applied to industrial soil in the context of brownfield regeneration

“…in concrete production, since this practice may allow to avoid landfilling as well as to reduce the consumption of virgin raw material. In addition, industrial soils originating from abandoned industrial sites may cause detrimental environmental effects related to the release of toxic metals and metalloids into the environment [3]. Therefore, the proposed treatment should also reduce the mobility of potential contaminants.…”

“…Therefore, the proposed treatment should also reduce the mobility of potential contaminants. Often, this goal is achieved through a stabilization/solidification (S/S) process, which involves the controlled addition and mixing of hydraulic binders with contaminated soils to form a monolith showing an improved environmental behaviour and high mechanical resistance [3,4]. In spite of this, the application of S/S treatments does not allow to obtain a product with a suitable particle size to be reused in substitution of natural aggregates in civil applications.…”
