Abstract :The study investigates the impact of different curing techniques on the compressive strength and absorption rate of laterised concrete, a sustainable material integrating laterite as a partial or full substitute for conventional sand. Over curing durations spanning 1 to 28 days, compressive strength and sorptivity of laterised concrete specimens were evaluated under varied curing conditions: water immersion, intermittent sprinkling, wet rug covering, plastic sheet covering, and air-drying. Results indicate a consistent trend: higher laterite content correlates with decreased compressive strength yet increased sorptivity. Notably, water immersion consistently yielded the highest compressive strength (31.68 N/mm²) and lowest sorptivity (0.0201 mm/√s) after 28 days, followed by intermittent sprinkling, wet rug, plastic sheet coverings, and air-drying, with the latter exhibiting the poorest performance. The study underscores the pivotal role of curing methods, revealing an inverse relationship between compressive strength and sorptivity. Moreover, as the curing duration extends, compressive strength improves while sorptivity diminishes, emphasising the enduring efficacy of curing. These insights accentuate the significance of selecting suitable curing strategies to enhance laterised concrete structures\\\' performance and durability, thereby advancing sustainable construction practices.
