The project aims to partially replace the coarse Aggregate which is going rare these days with Lightning Insulators which is discarded in landfills and are not environmentally friendly either. A lightning arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or

... ing surge, which is very similar) travels along the power line to the arrester, the current from the surge is diverted through the arrestor, in most cases to earth. If protection fails or is absent, lightning that strikes the electrical system introduces thousands of kilovolts that may damage the transmission lines, and can also cause severe damage to transformers and other electrical or electronic devices. Lightning-produced extreme voltage spikes in incoming power lines can damage electrical home appliances or even produce death. These insulators thus represent a residue from electric poles. These insulators after used, are waste for the environment and so recycling or locking up of this waste is very crucial from the environmental point of view too. The main advantage of this type of concrete over the conventional ones is the reduction in the quantity of coarse aggregates and thus to minimise the initial cost. The results of this study indicate that the Lightning Insulators can be used as an ingredient in the range of certain limits to improve expanded concrete. As a result, it can be said that the usage of the arrestors in concrete, decreases its detrimental environmental effect. Moreover, the insulators have some beneficial effect on concrete properties. Therefore, the results of this investigation result into lots of benefits for industrial growths in eco-friendly way.
