Aerogel　is　a　synthetic　porous　ultralight　material　with　very　low　thermal　conductivity,　and　it　is　mainly　used　in　buildings　for　external　insulation　in　the　form　of　blankets.　In　this　study,　the　development　of　high-strength　concrete　with　a　partial　replacement　of　sand　with　aerogel　powder　and　aerogel　beads　is　presented.　Compressive　strength,　thermal　conductivity,　and　shrinkage　measurements　have　been　conducted,　and　the　results　indicate　that　a　replacement　of　sand　with　30%　aerogel　beads　leads　to　a　high　compressive　strength　(70　MPa)　and　relatively　low　thermal　conductivity　(1　W/mK)　concrete.　©　2025　by　the　authors.
