The filling state and cracking of the filled concrete, and further detection of the moisture change state of the filled concrete over time, are very useful for the durability evaluation of concrete buildings, etc., and it is constituted as a concrete filling detection, moisture content, etc. that can be easily measured.

混凝土在現代的建築領域中,在大樓等的骨架、住宅的基礎部等的建築物的利用上是不可或缺的。 In the field of modern construction, concrete is indispensable for the use of structures such as skeletons of buildings and foundations of houses.
建築物新建時,將混凝土充填至模架是不可少的,此時,掌握是否正確填充對於工程的品質管理來說非常重要。 When a building is newly built, it is essential to fill the formwork with concrete. At this time, knowing whether the filling is correct is very important for the quality control of the project.
此外,以往在現有建築物的維護管理中,建築物的耐久性係藉由「錘擊測試」、「核心移除」等方法而 得的壓縮強度、中性化深度來評估。 In addition, in the past, in the maintenance management of existing buildings, the durability of buildings was determined by methods such as "hammer test" and "core removal". The obtained compressive strength and depth of neutralization are evaluated.
特別是由於混凝土中的水分會影響中性化速度,間接地影響耐久年數之外,亦與破裂、透氣係數的測量有關,故在經時的耐久性評估併用水分測量是有用的。 In particular, since the moisture in the concrete will affect the neutralization speed and indirectly affect the durability years, it is also related to the measurement of cracking and air permeability coefficient, so it is useful to use moisture measurement in the durability evaluation over time.
為更正確地掌握建築物的耐久性、壽命,強烈要求例如從澆注時到澆注後經時測量、觀察混凝土壁面等之混凝土的充填狀態、水分狀態、水分值傾斜狀態。 In order to grasp the durability and life of buildings more accurately, it is strongly required to measure and observe the concrete filling state, moisture state, and moisture value slope state of concrete walls and the like from the time of pouring to the time after pouring.
專利文獻1已揭示一種由電極部、電容檢測電路、輸出部構成的電容式水分含量感測器,其中,電極部係由以不從接觸檢測對象物之構造物的壁面朝向檢測對象物大致突出的方式與電極面大致並行配置在壁面的一對電極構成;電容檢測電路係以該電極部的一對電極構成的電容器區域做為檢測區域,檢測以存在於檢測區域內的水分含量決定的電容值;輸出部係輸出相當於由電容檢測電路所輸出之檢測到的電容值之值的電量。
但是,專利文獻1的電容式水分含量感測器係將電極部設為由以不從接觸檢測對象物之構造物的壁面朝向檢測對象物大致突出的方式與電極面大致並行配置在壁面的一對電極構成,將以該電極部的一對電極構成的電容器區域做為水分含量的檢測區域,因此,推測只能在構造物的壁面附近形成電容器區域也就是水分含量的檢測區域。
