Abstract
The last decade has witnessed a heightened interest in making buildings more sustainable, which has been fueled largely by the increase in energy costs and advancements in manufacturing technology. Lighting consumes a substantial amount of this energy, making it necessary to look for alternative technology that depends more on natural lighting. This study investigated a novel building envelope material that consists of optical fibers embedded in concrete. The paper discusses the mechanical effects of the inclusion of plastic optical fiber (POF) into self-compacting mortar (SCM), by producing special boards with dimensions (300×150×15mm), (300×150×25mm) and (300×150×50mm) with 4% POF volume fraction content and (2.0, 3.0mm) diameter, which could be used in many applications (ceilings, external walls, partitions, floor tiles, etc.). The experimental results show that an optical fiber can be easily combined with self-compacting mortar (SCM) but with very high skillness. The results indicated that the absorption values for boards with 15, 25 and 50mm thickness are increased by about (2.70, 2.92 and 3.2%) respectively, as compared with reference board and all results within requirement. Handleability index in translucent concrete boards decreases due to the inclusion of POF and the breaking moment between (189.90-1616.5Nm/m) for samples at 28-days age.
