Effect of a Crystallizing Admixture on Concrete Properties: Italian Concrete Days
Abstract The present work aims at investigating the effect of a crystallizing admixture on concrete properties. Several concrete mixtures, properly prepared with different W/C ratios and different cement contents, have been compared with similar ones containing different dosages of Crystallizing admixture. The crystallizing effect of the product has been assessed and discussed both on fresh and hardened properties of the mixtures studied. Evaluations on setting time and strength development have been done on reference and trial mixes. Specific testing like the evaluation of chloride ion diffusion, accelerated carbonation testing and other tests have been performed to have an overview on all aspects on different levels of permeability. The crystallizing effect has been detected and demonstrated with a Scanning Electron Microscopy (SEM-EDS). The pictures of crystals growing into the capillary voids are intended to demonstrate the blocking effect of the cement matrix through the crystallizing compounds.
