Abstract: Conventional concrete strength testing methods, such as cube compression, are destructive and time-consuming, and delaying critical construction decisions.This study aims to validate the Concrete Maturity Meter (CMM), a non-destructive, real-time monitoring tool based on the maturity method, for assessing compressive strength in M20, M25, and M30 concrete grades using OPC and PPC cement with river sand and M-sand.Twenty cubes per grade were cast, with temperature sensors embedded in selected cubes to record time-temperature data, calibrated via regression models per ASTM C1074.Strengths predicted by CMM were compared with Compression Testing Machine (CTM) results at 1, 3, 7, 14, 21, and 28 days under standard curing conditions (27 0 C, IS 456).Results 1 showed strong correlations (R 2 = 0.95), with average errors of 0.86% (M20), 1.8% (M25), and 1.02% (M30), confirming CMMs reliability across grades and materials.This approach enables faster, safer, and sustainable construction by reducing testing time and material waste.Future work includes integrating AI for predictive analytics, applying CMM to advanced concretes, and standardizing maturity curves for broader adoption.
