Asbestos is the commercial name given to a group of fibrous hydrated silicates that exists naturally in rock formations of earth crust. Based on the mineral composition it has been divided into two major groups as amphibole group which includes amosite, anthophy lite, crocidolite, actinolite, amosite, chrysotile and serpentine group which includes the most abundant variety of asbestos where chrysotile constitutes 98% of the world production. The major source of asbestos is through metamorphic rocks which enter in to atmosphere. Mixture of asbestos paste and cement which is compressed by steel rollers will be used to make asbestos cement pipes, they can be drilled and joined with other pipe at any part but threading like iron is not possible and if there is any leakage at threads it will be worse as time passes. While laying these pipes, good supporting soil bed and flexible joints at suitable points are recommended to prevent leakages as well as sustaining for long period of time. The physical properties such as low heat conductivity, flexibility, infusibility high resistance to sound and electricity, structural stability, anticorrosive and cost effective nature make asbestos most suitable substitute material for iron in water supply application. Now a days it has been practicing in many of the engineering applications for various requirements. © IAEME Publication.
