To clarify the generation and floating behavior of scum, we conducted a detailed observations of scum using multiple fixed-point cameras and sediment surveys in the Hirano River, an urban tidal river in Osaka, Japan. Organic mud derived from sewage was deposited in two separate areas, of which the upstream was the main source of scum in the river. The floating behavior of scum was mainly dominated by tide, and scum accumulated at the stagnant point at rising tide. Scum was frequently observed at the bend of the river channel, suggesting that the local flow structure had a considerable influence on the behavior of scum over a wide area of the river.","PeriodicalId":52233,"journal":{"name":"Journal of Japan Society of Civil Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68174930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The degree of hydration reaction of in-place concrete is regarded as a useful reference to estimate the development of the strength of concrete. Based on the concept of On-Site Visualization, this paper presents a new approach to monitoring the hardening progress of fresh concrete/mortar using plastic optical fiber (POF) sensors. The principle of sensing is illustrated conceptually. The fundamental experiments were carried out to investigate the change in the visible light intensity reflected from the sensing plane of POF sensor during the hydration of concrete/mortar at early ages. The typical influence factors were also studied. The hydration process of concrete/mortar at early ages was well observed by the POF sensors. The direction of POF sensor installation had a significant effect on the pattern of light intensity change. When the sensor was installed pointing downwards, the light intensity dropped at first but increased rapidly in a few hours, which indicated the phase evolution when the free water disappeared in the hardening concrete/mortar. While the sensor was set up pointing upwards, the light intensity dropped in the first stage and then grew up slowly with time. Furthermore, the hydration process of concrete was characterized by introducing the nominal refractive index (NRI), which could be calculated from the measured light intensity. Thus, the hydration of concrete could be divided into three stages approximately according to the curve of NRI of concrete (when the sensor was installed pointing upwards), which coincided with the common knowledge of the concrete hydration process. Finally, the future work is discussed briefly.","PeriodicalId":52233,"journal":{"name":"Journal of Japan Society of Civil Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68175019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
