The replacement rate varied between 15% and 50%. The results indicate that recycled aggregates are, indeed, suitable to be incorporated into ready-mix concrete production. The impact on the final product's performance is different for the two cases examined herein. Incorporating aggregates from ...

• The observation of the fatigue behavior with respect to the concrete strength revealed that the deflection exhibited the largest increase rate below 1000 cycles, increased gradually until 100,000 cycles and stabilized until 2 million cycles. The strain measured at the center of the CFRP tendon...
The trend of curves of stress-strain are similar for both recycled and conventional concretes, however, a slight shift—due to differences MOE and ultimate strain—was observed in recycled ones. The shift is significant when the substitution rate is high. The longitudinal strain of the recycled ...
Yu et al. [4] proposed an algorithm for a more realistic creep analysis with a rate type creep formulation based on a Kelvin chain model to capture the effects of humidity and temperature variations. They also considered changes in the degree of hydration according to humidity and temperature,...
The cost of prefabri- cated buildings was proven to be 26.3% to 72.1% higher than that of conventional buildings and is highly linearly correlated with the prefabrication rate. Jiang et al. [16] studied the constraints on the promotion of prefabricated construction in China. In their findings...

Two different diameter rebars were used: D10 for the shear reinforcement and D22 for the main rebar of the specimens (see Section 3.1 for further details). The uniform building code [31] pertains to RC design in earthquake zones and specifies that the ratio of the tensile stress to the ...
Recent studies have revealed that the fluidity rate of fly ash (FA)-based AASCCs decreases as the ratio of ground-granulated blast-furnace slag (GGBFS) substitutes increased [13–16]. This was attributed to the angular morphology and faster reactivity of GGBFS in a highly alkaline environment....
