This study explores the application of blockchain technology to enhance the integrity and reliability of concrete test logs in civil engineering projects. Traditional methods of recording and managing concrete test data are susceptible to tampering, errors, and loss, which can compromise structural safety and project outcomes. The proposed solution leverages cryptographic hashing and immutable distributed ledgers to securely timestamp each test entry, ensuring tamper-proof records with verifiable audit trails. The system integrates seamlessly with existing concrete testing workflows by capturing test data directly from devices, encrypting it, and submitting hashes to a blockchain network. Smart contracts automate verification processes, improving transparency and accountability. The study further evaluates the solution’s security performance, transaction efficiency, and usability through simulation and prototype testing. Results indicate significant improvements in data immutability, regulatory compliance, and long-term storage capabilities compared to traditional systems. However, challenges such as transaction latency, scalability, industry resistance, and data privacy require careful mitigation through hybrid blockchain models, targeted training, and regulatory engagement. Future directions include integration with Internet of Things (IoT) sensors for real-time monitoring, AI-driven predictive analytics, and interoperability with Building Information Modeling (BIM) systems. This blockchain-enabled approach promises to transform construction quality assurance by embedding security and transparency throughout the data lifecycle, fostering safer, more accountable, and digitally advanced civil engineering practices.
