Abstract
Atmospheric conditions and moisture loss of early age cementitious material can lead to cracking and may affect the durability and serviceability of the cementitious materials. The real-time monitoring of these conditions of cementitious materials (cement, mortar, concrete, pozzolana) at an early age is vital for quality control and durability. The present study proposes an Internet of things enabled real-time monitoring system for early age cementitious materials. The system consists of three sensors (DS18B20, DHT-11, moisture sensor) and a Wi-Fi microcontroller. The system measures concrete/atmospheric temperature, relative humidity, and moisture content inside the fresh cementitious materials and posts the data on the internet. The proposed system is effective in the prediction of moisture loss and shrinkage in early age concrete which is beneficial to the construction industry.
