                <dct:description xml:lang="en">Bedrock used as aggregate resources is geologically a rock, and rocks exhibit various chemical compositions depending on their constituent minerals. Depending on the characteristics of the chemical composition, they may exhibit elements harmful to the human body or characteristics that affect strength or safety when used as aggregate. Therefore, the purpose is to identify geochemical characteristics through various test analyses to improve aggregate quality. XRD is a test to identify mineral composition and composition ratio, and XRF is a test to identify chemical composition and content. Alkaline aggregate potential reactivity test can be used to maintain building strength and safety, ARD can be used to identify environmental pollution and building strength, and Rn (radon) and F (fluorine) tests can check for the emission of substances harmful to the human body.</dct:description>
