Abstract: This paper investigates the effect of carbonation on the micro-mechanical properties and frost salt scaling resistance of 1-year old blast furnace slag cement and ordinary Portland cement pastes with w/c 0.45. The micro-mechanical properties are evaluated by the nano-indentation technique and the results are used to evaluate the behaviour of these pastes under frost salt attack. Frost salt scaling damage on the paste samples is modelled according to the glue-spall theory with the aid of Delft Lattice Model. Additionally, the carbonated cement paste microstructures are characterized by ESEM/BSE.

Keywords: Carbonation, micro-mechanics, nano-indentation, modelling, durability
