Senior researcher mineral activation and productization at VITO with a drive for transforming mineral waste into low-carbon construction materials. Long distance runner and nature lover.
In Antonino's first paper as post-doc at VITO he shows how to carbonate aerated concrete to make it into a reactive supplementary cementitious material doi.org/10.1016/j.co...

This new paper investigates the durability of cement containing internal sulfides coming from tailings. What happens when wet–dry cycles — typically used to accelerate external sulfate attack — are applied to mortars and pastes containing pyritic materials?

Assessment of internal sulfate attack in cement partially replaced with pyritic materials using wet–dry cycles - Materials and Structures
When used in cement-based materials, sulfidic minerals such as pyrite may oxidize in the long term and their oxidation products may react with the cementitious matrix. This long-term instability of su...

We recently discovered that Mg-silicate slags can be modified into reactive raw materials for mineral carbonation by the formation of akermanite.
