Study on the Mechanical Properties of Glass Fibre Reinforced Aerated Concrete with Aluminium Powder as Aerating Agent

The demand for novel technology for manufacturing lightweight concrete has increased in the global construction industry. Therefore, studies that explore alternative lightweight concrete systems for structural applications are urgently needed. The objective of this study is to develop Fibre Reinforced Aerated Concrete (FRAC) by the addition of 1%, 1.5%, 2% and 2.5% of glass fibres. Fibre Reinforced Aerated Concrete is examined under compressive, flexural, and splitting tensile strengths. The foaming agent used is aluminium powder. Aerated Concrete was strengthened by replacing cement with fly ash and the properties of the Aerated Concrete were enhanced by the addition of glass fibres. The addition of glass fibres will enhance the strength of aerated concrete in compression, Tension and in Flexure. The strength of aerated concrete is maximum for 2% of fibres than other fibre percentages. The study mainly focuses on the comparison of the ability of Glass Fibres in increasing the mechanical properties of the Aerated Concrete (AC) compared to the control specimen.
