Deterioration mechanism of cementitious materials under acid rain attack

Pore structure in concrete exposed to acid deposit

“…Many research studies have been examined the microstructure of cementations materials [6][7][8][9][10][11]. Zhang carried out experiments on the effect of curing on the degree of capillary porosity of concrete in a tropical environment [12].…”

A Parameter Ascertainment Method for the Skeleton Curve of Corroded Reinforcement Concrete Members with Flexure and Compression

“…According to (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), we can determine the six parameters of skeleton curve of corroded compression-bending members. e difference of skeleton curve of the damaged and undamaged members is that they have the different the material parameters.…”

“…For example, wind, waves, corrosive environment, and extreme temperatures all can impact the existing structures. During the entire service life of the RC structure, the continuous penetration of harmful ions induces cracking and spalling of the concrete cover [1][2][3], degradation of the bond strength [4][5][6][7], and decrease of the material strength [8][9][10][11][12]. In seismic-prone regions, the corrosion damage of the structures would reduce their lateral load-resisting capacity in a seismic event significantly [13][14][15][16].…”

Impact performance of specimens subjected to fatigue loading – experimental investigation

“…de-icing salts for road maintenance). The phenomenon of chemical deterioration has been extensively investigated with regard to the effect of acid rain on concrete structures in [5,6].…”
