Abstract
There are many factors that can cause problems in the application of the lightweight air-trapped soil in the field. Temperature is one of them. However, the effect of temperature on the characteristics of lightweight air-trapped soil has not been studied. Thus, this experimental study is conducted. This study considers three different unit weights of lightweight air-trapped soils, 6, 8, and 10 kN/$m^3$ which are mostly applied to the field. The lightweight air-trapped soil specimens are cured in the condition of different temperatures based on the characteristic of temperature of Korea. The unconfined compression tests are conducted on the prepared specimens. The settlement behavior of lightweight air-trapped soil on temperature is observed. A photograph is taken using SEM to determine the transformation of air-foams inside the lightweight air-trapped soil on curing temperature. As the results, the effect of curing temperature on the characteristics of lightweight air-trapped soil including compressive strength, settlement, and formation of air-foams is confirmed. Finally, based on this study, the allowable curing temperature of $8^{\circ}C{\sim}25^{\circ}C$ which can guarantee the quality of lightweight air-trapped soil is proposed.
