The quality problems of ceramsite concrete in the construction are analyzed,and the quality control points and construction technology of ceramsite concrete are discussed according to the different situations encountered in the actual construction process,and corresponding technical measures are taken to improve the construction quality of ceramsite concrete.Through the experiment,the influence of ceramsite types on the dry apparent density and compressive strength of ceramsite concrete under different mix ratios was explored,so as to obtain the best ceramsite concrete mix ratio to meet the engineering needs.
