Abstract：

This　study　prepared　a　sulfoaluminate　cement　with　high　electromagnetic　wave　transmission　performance　by　adding　air　entraining　agent　and　glass　powder　and　revealed　the　related　mechanism.　The　test　results　showed　the　air-entraining　agents　and　glass　powder　cannot　affect　the　type　of　hydration　products　of　the　sulfoaluminate　cement.　The　addition　of　the　air-entraining　agents　and　glass　powder　reduced　the　dielectric　constant　of　the　SAC　while　increasing　the　magnetic　permeability.　The　air-entraining　agents　and　glass　powder　increased　the　transmittance　with　a　maximum　value　of　60.2　%,　illustrating　the　electromagnetic　wave　transmission　performance　of　the　sulfoaluminate　cement　could　be　improved.　The　electrical　resistivity　of　the　sulfoaluminate　cement　with　the　air-entraining　agents　and　glass　powder　did　not　change　significantly　because　the　air-entraining　agents　increased　the　electrical　resistivity　and　the　effect　of　the　glass　powder　was　the　opposite.　The　strengths　of　the　sulfoaluminate　cement　with　the　air-entraining　agents　and　glass　powder　decreased.　©　2024　Elsevier　Ltd
