Study of water seepage into concrete structures using fiber sensor
Water seepage in concrete is commonly found in deteriorated concrete buildings or even defective water pipes. It is a prevalent issue in buildings, typically caused by prolonged exposure to pools of water. Over time, concrete becomes increasingly porous where it will start to allow water to seep in,...

| description | Water seepage in concrete is commonly found in deteriorated concrete buildings or even defective water pipes. It is a prevalent issue in buildings, typically caused by prolonged exposure to pools of water. Over time, concrete becomes increasingly porous where it will start to allow water to seep in, posing detrimental threats to inhabitants of a building if left undetected. Therefore, it becomes extremely critical to pinpoint the location of water leakages for repairs to be done. It will be beneficial if water seepage can be detected before the occurrence of building failures, where restoration can be conducted before any concrete accidents take place. This project aims to measure and monitor the detection of water seepage due to cracks formation in concrete using sensors, with the aid of Plastic Optical Fibers (POF). Sensors designed to detect water seepage will have their own unique configuration, and superabsorbent polymers (SAP) were utilized in the process. The selected sensor will then be embedded in various materials to establish a relationship of whether a change in volume of water absorption will lead to differences in the readings collected from the photoelectric sensor. Eventually, the feasibility of the designed sensors will be assessed, and the Davis-Wilson empirical formula will be used to understand seepage losses. |
