Abstract：

The　electromagnetic　properties　of　magnesium　silicate　cement　were　measured　by　waveguide　method.　The　effects　of　magnesium‑silicon　ratio　and　curing　temperature　were　analyzed　and　then　the　mechanism　was　analyzed　based　on　the　microscopic　test　results.　The　results　show　that　the　early　age　strength　of　magnesium　silicate　cement　paste　could　significantly　be　enhanced　by　increasing　the　curing　temperature.　The　real　part　of　the　complex　permittivity　increases　with　the　increase　of　magnesium‑silicon　ratio　and　curing　temperature.　The　imaginary　part　of　the　complex　permittivity　and　the　tangent　of　the　loss　angle　increase　by　improving　curing　temperature.　To　compare　with　magnesium‑silicon　ratio，the　transmittance，reflectivity　and　absorptivity　are　more　obviously　affected　by　the　curing　temperature.　The　microscopic　test　results　indicate　that　the　water　content　and　pore　structure　have　an　important　influence　on　the　electromagnetic　properties　of　magnesium　silicate　cement　paste.　©　2024　Tongji　University.　All　rights　reserved.
