The growing adoption of industrialized construction methods has positioned concrete panelized wall systems as a viable alternative to conventional building techniques. This study investigates the usage of concrete panelized wall systems in building construction, with particular emphasis on evaluating their structural performance through material strength assessment. The primary objective of the research is to determine the compressive strength characteristics of concrete panels produced under different concrete classifications and to examine the reliability of non-destructive testing methods in assessing in-situ concrete strength. An experimental research design was employed, involving laboratory-based compressive strength tests on concrete specimens representing selected concrete classifications commonly used in panelized wall systems. In parallel, rebound hammer tests were conducted to evaluate surface hardness and estimate compressive strength in a non-destructive manner. The results obtained from the rebound hammer tests were analyzed and compared with laboratory compressive strength values to assess consistency, and practical applicability for quality control purposes. The findings revealed that higher concrete classifications exhibit improved compressive strength performance, confirming their suitability for load-bearing and structural wall applications. The rebound hammer test demonstrated a reasonable comparison with laboratory results, indicating its effectiveness as a rapid assessment and preliminary quality evaluation tool, although limitations in accuracy were observed depending on concrete class and surface conditions. These results highlight the importance of proper calibration and complementary use of destructive and non-destructive testing methods in evaluating concrete panel performance. The study provides practical guidance for engineers and practitioners implementing panelized concrete wall construction systems.
