Carbonation-induced corrosion is usually considered in uniform or generalized corrosion. This true for small laboratory samples but not necessary the case real reinforced concrete structures built with multilayers reinforcement. Multi-layers reinforcement could lead to a galvanic between first de-passivated layer closed surface and deeper layers still passivated. The present paper compares dens...

Basic Oxygen Furnace slag contains heavy metals, including vanadium, chromium and molybdenum. The leachability of these elements determines the industrial applicability slag-based building products. This study investigates post‑carbonation leaching metals from activated BOF pastes with focus on activator dosage type (sodium potassium citrate). Results reveal that high degree brownmillerite hydr...

Globally, coal-fired power plants are the largest industrial source of carbon dioxide (CO2). CO2 emissions from flue gas have potential for direct mineralization with electrostatic precipitator fly ash particles in the field. Demonstration scale accelerated mineral carbonation (AMC) studies were conducted at the Jim Bridger Power Plant, a large coal fired power plant located in Wyoming, USA. AM...

Carbonation of cement-based materials may lead to durability problems, so that it is necessary find a way reduce the effect carbonation on concrete durability. This study investigated effects cellulose nanofibrils (CNFs) carbonated materials. Two dosages CNFs were used prepare cement pastes and mortars. Before after accelerated (4 % CO 2 concentration 57 relative humidity), their microstructure...
