Research on Preparation Technology of Fair-faced Concrete in Highway Engineering
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.
