Abstract :
Using concrete in buildings effects building’s architecture in different ways. Among these, we can mention the passing of light which highly influences the architecture of the buildings. Ultra-high performance light transmitting concrete is one of the suitable answers to this issue, but to use this kind of concrete, it is required to have enough information about concrete specifications and the amount of light transition through it. To manufacture light transmitting concrete samples, Polymethylmethacrylate (PMMA) optical fibers are used. The number and distance between optical fibers are important, because it’s not only affects the physical properties of concrete but also is a determinative factor for the final cost of concrete as well. The distance between optical fibers has an effect on determining the size of used aggregates to prepare concrete. This research mentions the necessity of comprehensive recognition of concrete and properties of Light transmitting concrete by dealing with the issue of transmitting light from concrete and its importance in buildings architecture. We can obtain enough information about the amount of light transition of this kind of concrete, compressive strength, fixe mixing plan that is Practical when we are using different ratio of optical fibers in light transmitting concrete , and the durability by manufacturing many specimen of light- transmitting concrete with 3,5,7,10,15 PMMA optical fibers in its. According to the gained data from these experiments, we can find an optimum ratio of PMMA optical fibers in light transmitting concrete from light transmitting and compressive strength view points, which is highly useful to construct and use this kind of concrete in modern buildings.
