FA reduces the heat of hydration, the risk of cracking and the water demand of the cement paste, which improves the compactness of the cementitious matrix (Wang et al., 2020) (Zhao et al., 2015) (Sun et al., 2003) (Li et al., 2005).
(Kocak et al., 2014) (El Khadiri et al., 2002) discovered that fly ash particles accumulate between clinker grains to form nucleation seeds for crystallization of cement hydration products such as C-S-H.
The glassy fly ash particles make the mixture more homogeneous (El Khadiri et al., 2002), (Vu-An et al., 2019).

Huang et al. [1] researched the vibration control effect of tuned liquid damper (TLD) based on large span transmission tower.
Battista et al. [2] envisaged nonlinear pendulum-like damper (NLPD) installed on the tower in order to reduce the displacement at the top of tower, and the efficiency of nonlinear pendulum-like damper was demonstrated.
Deng et al. [3] studied wind vibration control experiment based on 500kV Jiangyin large span tower, and verified the design program of tuned mass damper (TMD) and viscoelastic dissipater (VED).
Liu et al. [4] presented a method to simulate tuned mass damper (TMD), and analyzed the control of wind-induced dynamic response for transmission tower-line system.
