Self-curing concrete is one of the special concretes in mitigating insufficient curing due to human negligence, paucity of water in arid areas, inaccessibility of structures in difficult terrains and in areas where the presence of fluorides in water badly affects the characteristics of concrete. The aim of the paper is to evaluate the use of water-soluble Polyethylene Glycol (PEG) as self-curing agent with partial replacement of conventional fine aggregate with lightweight fine aggregate and to optimize the quantity of PEG. Flexural behavior of self-curing concrete of M30 grade is casted by replacing optimum percentage of natural fine aggregate with lightweight fine aggregate and optimum percentage of PEG by weight of cement. The fine aggregate was partially replaced with 25% quarry dust. From the optimum percentage of lightweight fine aggregate replacement, optimum percentage of PEG -400 was found out by varying the percentage of PEG from 0%, 0.5%, 1% and 1.5% by weight of cement for M30 grade of concrete. The compressive strength, split tensile strength and flexural strength of self-curing concrete with varying quantity of polyethylene glycol are evaluated and compared with the conventional concrete specimen.


Proper curing of concrete structures is very much essential to ensure their meet, intended performance and durability requirements. In conventional construction, this is achieved through external curing, applied after mixing, placing and finishing. Internal Curing (IC) is a very promising technique that can provide additional moisture in concrete for more effective hydration of cement and reduced self-desiccation. IC implies the introduction of a curing agent into concrete that acts as an internal source of water in the concrete structures.
