Light Transmitting Concrete Pdf Free
Light Transmitting ConcreteThe fibers run parallel to each other, transmitting light between two surfaces of the concrete element in which they are embedded. Thickness of the optical fibers can be varied between 2 µm and 2 mm to suit the particular requirements of light transmission.
Optical fibers transmit light so effectively that there is virtually no loss of light conducted through the fibers; in fact, it’s even possible to see colors through the concrete.Originally, the fiber filaments were placed individually in the concrete, making production time-consuming and costly. Newer, semi-automatic production processes use woven fiber fabric instead of single filaments. Fabric and concrete are alternately inserted into molds at intervals of approximately 2 to 5 millimeters.
Smaller or thinner layers allow an increased amount of light to pass through the concrete. Following casting, the material is cut into panels or blocks of the specified thickness and the surface is then typically polished, resulting in finishes ranging from semi-gloss to high-gloss.
The concrete mixture is made from fine materials only:It contains no coarse aggregate. The compressive strength of over 10,000 psi is comparable to that of high-strength concretes. However, due to the manufacturing process, elements for structural applications have not yet been produced.
