In order to promote efficient use of waste concrete in Chongqing, the building area estimation method is employed to estimate the waste concrete output from 2012 to 2018, and the gray model is used to predict the waste concrete output from 2019 to 2023. By Matlab programming, the waste concrete output in Chongqing will reach 3181.14t in 2023, which is 1.44 times that in 2012. The results show that the gray model can accurately forecast the output of waste concrete in Chongqing in the short and medium term.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
