Concrete is the most widely used for construction materials in world. Water content of concrete an important parameter terms durability structures. Terahertz (THz) waves, which a porous and absorbable material, have been studied order to establish new non-contact inspection technology maintenance In this study, THz transmittance reflectance drying process were measured with 60 GHz GUNN diode absorption coefficient analyzed various water contents. It shown that quantitative detection below 10% possible at surface area concrete.
