摘要:Present scenario of construction industry is facing problems of organizations of by-product materials like disposal and ground water contamination etc. that are producing naturally in the process of converting one form to other. Scientific experts are trying to create new building materials from these by-product materials that will fit in current situations to avoid damage to society and environment. The addition of these by-product materials to make new building materials makes the environment stable and also produces the durable building products. Aerated concrete is one which uses some of these by-products like fly ash, GGBS etc. and reduces the use of natural sand and cement with enhanced mechanical properties like compressive and tensile strength. As aerated is concrete is poor in flexural strength to improve this property steel fibres are used in proportion This paper mainly focuses on the mechanical properties of aerated concrete like compressive, tensile and pull-out strength with and without addition of steel fibres. After addition of fibres mechanical properties are enhanced up to certain extant.
