Indian Concrete Journal - ICJSummary: This paper describes the results of a comparative study between concrete mixes containing natural plasticizer (NP) and chemical plasticizer (CP) as well as the control mix concerning durability performance. NP used in this investigation was prepared from the extract of rain tree pod and used in concrete. Tests on resistance to acid attack, water absorption, chloride ion penetration, water permeability, and sorptivity were carried out as per codal provisions. The chloride permeability of concrete was moderate with the addition of the developed natural plasticizer. The strength decrease of cubes subjected to acid attack with the addition of NP was lesser in comparison to the control mix. The results obtained show that the concrete mix with NP exhibited better performance than the control mix and worked equally efficiently as the mix with CP with respect to durability. Therefore, the NP prepared from the rain tree pod extract has the potential to be used as an alternative to CP for enhancing durability of concrete.
