Abstract The thermal gravimetric analysis (TG) is a common method for the examination of carbonation progress cement-based materials. Unfortunately, properties some components complicate evaluation TG results. Various hydrate phases, such as ettringite (AFt), C–S–H and AFm, decompose almost simultaneously in temperature range up to 200 °C. Additionally, physically bound water released same rang...
