Abstract
This study is a pioneer investigation to enhance the insulation capacity of the conventional aerated concrete using hydrophobic aerogels. As the main test parameters, aerogel content varied from 0% to 40% of the foam volume. Test results showed that the compressive strength of aerated concrete containing aerogels was lower by 17%~34% than that of the conventional aerated concrete. In addition, the effect of the aerogels on reducing thermal conductivity of aerated concrete is insignificant because of the partial condensation and abnormal distribution of the hydrophobic aerogels. Hence, further hydrophilic treatment for the surface of aerogels is recommended to minimize the decrease in compressive strength and enhance the insulation capacity of aerated concrete.
