This study describes the properties of High Volcanic-Ash Concrete according to the replacement method and ratio of volcanic-ash. For purpose of this study, the tests of slump, setting time, bleeding, compressive strength, tensile strength, modulus of elasticity, heat of htydration, and far-infrared emissivity were performed according to the mix proportion of concrete according to the replacement method (Control Mix, C 10, 20, 35, 50, 70, A10, 20, 35, 50, 70). According to test results, the compressive strength of the concrete using the volcanic-ash as a part of fine aggregate (Mix A) was higher than that of the concrete using the volcanic-ash as a part of cement content (Mix C). The compressive strength of concrete in the mix C decreased with the increase of replacement amount of the volcanic-ash and the compressive strength of concrete for the mix A and mix C increased with the increase of the curing age. The heat evolution of the concrete using the volcanic-ash as a part of cement content (Mix C) was lower than the concrete no using the volcanic-ash. The heat evolution of concrete decreased with the increase of the replacement amount of the volcanic-ash. The far-infrared volcanic ash concrete as well-being concrete may be highly effective for energy saving and anti-bacteria.
