Concrete is an important building material for building construction.Concrete pouring is the key work of concrete construction,and its quality directly affects the overall quality of the engineering.Therefore,in the construction of roads and bridges,concrete materials and cast-in-place concrete are of great concern to construction units and construction personnel.This paper focuses on the analysis of the common quality problems of cast-in-place concrete in road and bridge construction,including inaccurate moisture ratio,damage to edges and corners;unreasonable material selection and matching ratio,low strength;the honeycomb state caused by the non-standard proportion and process,and puts forward corresponding solutions,hoping to provide reference for the construction personnel.
