“…If one compares these values, it is possible to conclude that ISR observed in concrete cores imposed a severe decrease in dynamic modulus of concrete (close to −45%). This fact represents the cracking process observed in the pile cap surface during the visual inspections and certifies the efficiency of this parameter as a good indicator of concrete damage due to ISRs [27,[41][42][43][44][45][46][47].…”

“…Among other parameters used to assess the frost resistance of concrete based on ultrasonic tests, one can also mention the so-called level of damage, D FT [40,41], and a measure in the form of a relative change in the transition time of the ultrasonic impulse occurring in the standard RILEM TC-176 [42]. More advanced models based on the dynamic modulus of elasticity of concrete are also adapted [40,43,44].…”

“…At 180 d, the shrinkage rates for the 25% and 0% fly ash specimens were 293.28 × 10 −6 and 370.06 × 10 −6 , respectively. Similar to volcanic ash, fly ash generates hydrated calcium carbonate and water-hydraulic calcium aluminate, which fill a portion of the water-retaining voids, limiting shrinkage [13]. In addition, fly ash can effectively replace a portion of the fine aggregate, resulting in a microaggregate effect [28].…”

“…Some studies have indicated that a more viable utilization of fly ash is as a substitute for the fine aggregate in concrete mixtures [4,11]. Contemporary research regarding concrete with fly ash as the fine aggregate (CFA) has focused on the concrete's mechanical properties [12][13][14][15], broadly confirming that the compressive and flexural strengths of CFA are superior to ordinary concrete. Few studies have considered the durability of CFA [15][16][17].…”
