Abstract
This article analyzes the reasons for the defects in plain concrete from various aspects such as raw material selection,mix design,casting construction,and later maintenance.By comparing the use of pure cement,single-fly ash,double-fly ash,and mineral powder in dif-ferent mix designs to prepare C35 strength grade concrete for highway bridge pier components,the main influencing factors affecting the appear-ance of concrete bridge pier components were determined through laboratory molded test specimens and cast-in-place test columns.关键词
