Abstract : Transparent concrete is a concrete based building material with light-Tran missive properties due to embedded light optical elements usually Optical fibres. Light is  conducted through the stone from one end to the other.  Therefore the fibres have to go through the whole object.  Transparent concrete is also known as the translucent  concrete and light transmitting concrete because of its  properties. It is used in fine architecture as a façade material  and for cladding of interior walls. In this paper, to integrate  the merits of concrete and optical fiber, for developing transparent concrete by arranging the high numerical aperture Plastic Optical Fibres (POF) or big diameter glass optical fiber into concrete. The main purpose is to use sunlight as a light source to reduce the power consumption of illumination and to use the optical fiber to sense the stress of structures and also use this concrete as an architectural purpose for good a...

1.   Aerogel        Aerogel holds 15 entries in the  Guinness Book of Records , more than any other material. Sometimes called “frozen smoke”, aerogel is made by the supercritical drying of liquid gels of alumina, chromia, tin oxide, or carbon. It’s 99.8% empty space, which makes it look semi-transparent. Aerogel is a fantastic insulator — if you had a shield of aerogel, you could easily defend yourself from a flamethrower. It stops cold, it stops heat. You could build a warm dome on the Moon. Aerogels have unbelievable surface area in their internal fractal structures — cubes of aerogel just an inch on a side may have an internal surface area equivalent to a football field. Despite its low density, aerogel has been looked into as a component of military armor because of its insulating properties.       This tiny block of transparent aerogel is supporting a brick weighing 2.5 kg. The aerogel’s density is 3 mg/cm3. 2.   Tr...
