Manufactured sand for the development of reinforced concrete spun pipes

•The effect of Msand replacement as a fine aggregate for the manufacture of RCC spun pipes was investigated.•Addition of Manufactured sand replacement slightly decreases the concrete workability.•Msand as a fine aggregate replacement increases then the compressive strength decreases and 50% replacement produces highest compressive strength.•RCC spun pipes manufactured with 50% replacement shows positive results in Three edge bearing and Hydrostatic test.
