Abstract

Curing is a critical process in concrete construction, ensuring adequate hydration for achieving the desired strength and durability. However, traditional methods, such as 28-day water curing, are often resource-intensive and misaligned with the fast-paced demands of modern construction projects. This study explores hot water curing as a sustainable and efficient alternative, leveraging IoT-driven digital technologies to optimize the process. The proposed smart curing system integrates components such as an Arduino microcontroller, relay modules, solenoid valves, and thermostats to maintain precise curing conditions, minimize water consumption, and promote early strength development. Experimental results demonstrate that curing concrete with hot water at 60°C for 12 hours achieves the required compressive strength, significantly reducing curing time and resource use. This approach not only aligns with sustainability goals but also supports the adoption of green construction practices, highlighting its potential to transform concrete curing in the context of renewable energy, green computing, and sustainable development.
