A comparative assessment of the effect of cement type on concrete durability.

In the current study, the effect of different types of cements (CEM I, II, III, IV and V), classified according to the European Standard EN 197-1, as well as the effect of different types of Type II additives on CEM I type of cement, were evaluated as far as their performance in carbonation and chloride exposure is concerned, for a service life of 50 years. Different types of supplementary cementitious materials (SCM) and water-cement ratios were examined. The evaluation was made using a software package, an analytical tool for the estimation of concrete service life when designing for durability under harsh environments, developed based on a unique analytical approach of all the parameters identifying the aggressivity of those environments, and validated using experimental data.
