Effect of CO concentration on strength development and carbonation of a MgO-based binder for treating fine sediment.

We previously described a MgO-based binder for treating fine sediment and simultaneously store CO. Here, we describe a study of the physical/mechanical characteristics and carbonation reactions of the MgO-based binder used to solidify/stabilize fine sediment in atmospheres containing different CO concentrations. Carbonation of the sediment treated with the MgO-based binder at the atmospheric CO concentration markedly improved the compressive strength of the product.
