Abstract
This study aimed to assess the metal content in commonly recycled industry waste used in construction materials, focusing on iron, lead, copper, zinc, cadmium, and magnesium. Experimental tests were conducted on five construction materials: glass, sand, fly ash F, and rubber. Toxicity Characteristic Leaching Procedure (TCLP) method and Fourier Transform Infrared (FTIR) Spectroscopy were adopted for the characterization of metals and other chemicals. The results were compared with TCLP regulatory levels to ensure the safety of metal contents. Three trials of tests were carried out for each test. Acceptable values were determined through outlier analysis based the ten percent rule. The PH level for the acidic acid extraction fluid was 2.88 ± 0.05. Glass exhibited a reportable amount of ion, measuring 0.13 mg/kg. It is expected that all of the waste materials will be non-hazardous based on the TCLP tests and be suitable for use as construction materials.
