Title:Concrete/cement alteration in acidic waters
In this seminar, we show experimental and reactive transport modeling results obtained from column and percolation experiments carried out at the laboratory scale to study the interaction between portland cement, calcareous rocks and acid waters.
The geochemical processes observed are discussed as a function of pH and composition of the injected fluids. Our findings are relevant for the assessment of cement/concrete durability in treatment plants under acid mine drainage conditions and CO2 injection wellbores.
