In this study, the mechanical, thermal and porosity
properties of mortar samples containing aerogel and silica fume under
different curing conditions
were investigated. For
this purpose, 0%,
0.25% and 0.50%
by weight of
silica aerogel as a cement additive and 10% silica fume as an industrial
waste material were incorporated in the cement mixtures. The prepared mortar
samples were exposed to curing process in water, the wetting-drying effect and
MgSO4effect for 16 weeks. The highest thermal conductivity reduction of 31.2%
was obtained from the water curing sample with silica fume addition at an
aerogel content of 0.25%. Maximum compressive and flexural strengths were
determined respectively from samples with silica fume addition at an aerogel
content 0.50% as 74.5 MPa and no aerogel content as 11.3 MPa by wetting-drying
curing. However, the lowest thermal conductivity coefficient was measured as
1.458 W/mK from the sample at an 0.25% aerogel content containing silica fume
which completed the curing process under the influence of MgSO4with a highest
compressive strength increase by 24.6%.
