title = "Benchmarking the CEMDATA07 database to model chemical degradation of concrete using GEMS and PHREEQC",
abstract = "The objective is on the implementation of a consistent thermodynamic database for cement systems at temperatures different from 25°C in geochemical computer codes based on mass action equation and constants (such as PHREEQC-2). The implementation of the cement/concrete thermodynamic database was verified first by comparing simulations of chemical detrimental reactions in cement systems using PHREEQC-2 and GEMS. Verification was done for simplified cement systems followed by a further verification addressing complex geochemical simulations of by means of benchmark calculations. The thermodynamic database for cement systems is used in studies to simulate the long-term evolution of geochemical conditions in the concrete in a near-surface disposal facility.",
