The concretes were characterized by their workability, mechanical resistance and porosity, and capillary absorption, water penetration, chloride migration and natural carbonation were evaluated (6 and 12 months). The results show that capillary absorption decreases with age, with HKC being significantly lower than HCP and HIC. Water penetration and chloride migration coefficient is higher for HIC at 28 days, the latter being reduced drastically at 90 days (75%). At 12 months, the carbonation depth is less than 5 mm, with a slightly lower yield of HCP and HKC with respect to HCP.}, note = {}, institution = {Universität der Bundeswehr München, Fakultät für Bauingenieurwesen und Umweltwissenschaften, BAU 3 - Institut für Werkstoffe des Bauwesens, Professur: Thienel, Karl-Christian}, }
