Vironment, the average RH was around 65 (see Section two.two), so it would generate a progressive drying on the samples, which could explain the gradual rise with time of electrical resistivity noted for the mortars. An additional attainable factor that could have contributed towards the differences among electrical resistivity and porosimetry benefits would be connected for the qualities of each technique as well as the geometry of the samples employed for every 1. On a single hand, compact pieces taken from cylindrical specimens with five cm diameter and 6 cm height had been tested with mercury intrusion porosimetry. However, the electrical resistivity was measured with the Wenner four-point test on cylinders with 22 cm height and ten cm diameter. In the case of cylindrical specimens with five cm diameter and 6 cm height, because of their reasonably smaller volume, soon after 250 days of exposure, the development of their microstructure would be more globally affected by the environmental conditions, and as a consequence by the abovementioned damaging processes created within this atmosphere, previously described.Materials 2021, 14,13 ofFor the cylinders with 22 cm height and ten cm diameter, their higher size and volume would entail that the external part from the sample would be a lot more influenced by the environment, whereas its influence could be reduce and delayed in the core of the sample. Then, the development from the microstructure towards finer pores could be greater within the core component from the sample, for the reason that the effects of environmental drying would have an effect on this component having a lesser degree, enabling a greater improvement of hydration and pozzolanic reactions [39,657]. The electrical resistivity measurements provide extra worldwide details about the microstructure from the sample [77] compared to mercury intrusion porosimetry, so these achievable differences inside the pore network in between unique components with the specimen could clarify the lack of coincidences between the resistivity measurements and pore size distributions. Despite the abovementioned arguments, each of the samples applied for measuring the electrical resistivity have been subject for the identical atmosphere during the studied time period, so the outcomes of this parameter for the analyzed mortars is usually compared. At early ages, the higher resistivity values showed by S and SF binders, may be related towards the hydration of slag [7], already explained. The low resistivity noted within the brief term for binary and ternary binders with fly ash (F and FL series) and their progressive growth with time (F, SF, and FL series), even overtaking the values of the other binders with slag (S and SL series) at the most up-to-date Ethyl Vanillate Data Sheet testing age, would show the effects of fly ash pozzolanic reactions [9,80], reducing the pore size, as well as the delay of their starting in comparison to slag and clinker hydration, previously talked about inside the discussion of total porosity results at 28 days. Ultimately, the higher electrical resistivity noted for binders which incorporate a minimum of 1 active addition (fly ash and/or slag) will be in keeping with other authors [77]. This would indicate a greater proportion of pores with modest sizes in their porous network, agreeing with benefits of porosimetry, which usually showed a greater pore refinement in those mortars in contrast with REF mortars, and MCC950 web particularly with L ones. four.two. Durability and Mechanical Parameters With regards to the durability-related parameters, the highest values in the steady-state chloride diffusion coefficient noted at 28.
