Self-curing concrete is a specialized type designed to address inadequate curing due to human
negligence, water scarcity in arid areas, unavailability of structures in difficult terrains, and the presence of
fluorides in water that can negatively affect concrete properties. This study investigates the use of polyethylene
glycol (PEG-400) as a shrinkage-reducing admixture to enhance self-curing, hydration, and strength. Additionally,
rice husk ash (RHA) and Alccofine are used as partial replacements for cement at 10% each, while the Robo sand
is used as a partial replacement at 25% of fine aggregate. The compressive strength, flexural strength and split
tensile strength of these modified specimens of concrete are evaluated and compared with those of conventionally
cured concrete.
