- Abstract
Concrete structures are widely used in construction due to their strength and durability. However, over time, cracks may develop within these structures due to various factors, potentially compromising their integrity. Non‐destructive testing (NDT) methods are essential for assessing the health of concrete without causing further damage. This paper presents an alternative Impact Echo (IE) method using a Do‐It‐Yourself (DIY) device for non‐destructive concrete crack detection. The DIY device employs low‐frequency accelerometers and relies on stress wave propagation principles to detect cracks. The proposed device utilizes off‐the‐shelf components, commercially available hardware parts, and open‐source software for detecting cracks in concrete. A fully functional prototype is developed using 3D printing and Printed Circuit Board (PCB) construction methods, with an emphasis on ease of assembly. To evaluate the effectiveness of the proposed device, a case study is conducted involving an intact plate and a plate with surface opening cracks to validate its proper functioning. This research contributes a practical, cost‐effective solution for assessing concrete cracks, making NDT techniques more accessible for various applications, including infrastructure maintenance and safety inspections.
