The experimental results show that an optical fiber can be easily combined with concrete and that the POF could provide a steady light transmitting ratio. Moreover, the FBG can be used as a sensing element for strain and temperature.
Hi, I would like to add some more points about the uses of optical fibers in concrete. Light transmitting concrete or transparent concrete or translucent concrete is a concrete (made of rich raw materials, low cost and simple production)based material with light-transmissive properties, achieved by embedding optical fibres in it. Light is transported through the fibre from one end to the other. Optical fibres convey light so perfectly that there is practically no loss of light carried through the fibres, without light-heat, light-electrical or photochemical process, and photoelastic effect. This type of concrete can be installed at an average cost of construction and increasing the visual appearance. The mix and materials used are associated with that of ordinary mix except for 3–5 per cent of materials is interchanged by volume using optical fibre. The cement used is 43-grade portland cement, general aggregate is used. The maximum water-cement ratio is determined to be 0.5. The compressive strength of the concrete is said to increase with 4 per cent of replacement of materials by volume. The fibres are inserted on expected paths during casting itself.

Hi, Using a plastic optical fibre in concrete mix makes it translucent.i.e the concrete are able to pass light through it , but does not allow air and water.
