Chemical retreating for gel-typed aerogel and insulation performance of cement containing aerogel

► Possibility of new type of cement composite using aerogel was studied. ► Gel-typed aerogel was prepared by methanol to mix with cement stably. ► No chemical changes of aerogel cement were confirmed by FT-IR and SEM. ► Thermal conductivity of aerogel cement decreases by 75% comparing to ordinary one.
