Study on Cycling Damage of Abrasion and Carbonization on Ship Lock Concrete

In the actual working conditions, ship lock concrete is affected by friction of ship’s hull and erosion wear traveling wave during flood period damaged CO2 in air waterfall period. To study performance degradation law under this condition, underwater method was used to approximate physical rising water period, accelerated carbonization simulate falling The duration abrasion are determined according design service index characteristics navigability. reflected carbonation depth anti-abrasion strength, composition pore structure evolution characterized based on Mercury Intrusion Porosimetry. analysis show that inland exhibits a more obvious deterioration trend action surface cycle, accelerates reaction certain extent.
