Abstract: There is a necessity for a modern method to evaluate the insitu strength of concrete thereby increasing the rate of productivity in concrete industry. This method can address immediate challenges faced such as predicting right time for formwork removal, post-tensioning, at low temperatures while the strength gain of concrete is hindered, optimizing concrete mix design and cold weather protection. The temperature is measured using wireless sensor that offers a simple solution to concrete maturity monitoring. The temperature and humidity on various days is observed. The compressive strength at 1,3,7,14 and 28 day is observed. This paper includes calculation of maturity index using Nurse-Saul equation. A graph is plot between maturity index and compressive strength. The best fit strength-maturity equation is chosen based upon the obtained curve and thereby the in-situ strength of concrete is evaluated.
