Light is conducted through the optical fiber one end to other. Light transmitting concrete is also knows as translucent concrete because of its transparent property. It is used in fine architecture as a decorative material and for internal walls. The main purpose is to use natural sunlight as a light source to reduce the power consumption of illumination and to use optical fiber to sense the stress of structure and also use this concrete as architectural purpose for good aesthetic view of the building. The present investigation aims to producing the light translucent concrete by using optical fiber with different percentage and comparing it with normal concrete. Different tests will be performed on the concrete specimen i.e. compressive strength test and light transmission test. Keywords: Light transmitting concrete, Litracon, Optical Fiber, Cement and Aggregate. 1. INTRODUCTION Concrete has a key role in development of infrastructure and housing. Due to great economic growth, population growth and space utilization worldwide, there is drastic change in construction technology. Small buildings are replaced by high rise buildings and sky scrapers. This arises one of the problem in deriving natural light in building, due to obstruction of nearby structures. Due to this problem use of artificial sources for illumination of building is increased by great amount. So it is very essential to reduce the artificial light consumption in structure. Fig. No.1 Litracon Block It is considered to be one of the best sensor materials available and has been used widely since 1990. Hungarian architect, Aron Losonczi, first introduced the idea of light transmitting concrete in 2001 and then successfully produced the first translucent concrete block in 2003, named Litracon. Since concrete is strong in compression and weak in tension and flexure. Fig.No. 2 Litracon Panel
