Abstract
This study is focused on feldspar and zeolite which have recently been attracting attention as an extension research of air-trapped soil, which has been studied extensively. Feldspar and zeolite are environmentally friendly minerals such as heat storage, antibacterial function and heavy metal filtration. In addition, two different tests have been carried out for the air-trapped soil by using feldspar and zeolite as aggregate instead of sand.

First, the unconfined compressive strength of the specimens prepared using feldspar and zeolite were analyzed and were compared with the results of the unconfined compressive strength of the specimens prepared using sand based on axial strain and curing days.

Second, the thermal conductivity and heat storage performance were analyzed by fabricating the bottom layer as the air-trapped soil with feldspar in actual size.

In the first test, the unconfined compressive strengths of the three specimens using the feldspar, two specimens using the zeolite and standard specimen using sand were measured at curing 7 days, 14 days, 21 days, and 28 days. The measured strength characteristics of specimens were analyzed and compared with sand – feldspar, cement – feldspar mixture ratio, No.6 feldspar(particle size 1mm) - feldspar powder (particle size 40μm) mixing ratio, sand – zeolite and cement – zeolite mixing ratios.

In the second test, three types of full-scale models were fabricated by using two types of the air-trapped soil using feldspar and one standard sand. Each model was analyzed and compared to the thermal conductivity and heat storage.
