Abstract
The purposes of this study is to secure subsidence stability and economical efficiency of lightweight foamed concrete. The composition of lightweight foamed concrete was designed for OPC by substituting with constant contents of calcium sulfaluminate and fly ash. It is found that the flow of lightweight foamed concrete decreased with early ettringite formation by CSA. The initial strength increased with the decrease of drying time of lightweight foamed concrete when CSA was substitution to 10%. The settlement deep of foamed concrete improved the settlement stability by replacing CSA, which prevented shortening of the coagulation time and bubble puffing.
