【 摘 要 】

This study aimed to determine the content of CaO and SiO2 in landfill mining residue and ceramic shard waste, the best composition variation in accordance with SNI 03-0691-1996 on Paving Block, and the best values in the selected composition variation as paving block material according to SNI 03-0691-1996 on Paving Block. The research consists of six test steps, namely visibility test, size test, compressive strength test, water absorption test, wear resistance test, and sodium sulfate resistance test. The X-Ray Fluorescence method was used to determine the value of Cao and SiO2 compounds in landfill mining residue and ceramic shard waste. The CaO and SiO2 content in landfill mining residues were 5.81% and 46.31%, while in ceramic shard waste the concentrations were 4.60% and 64.33%. The selected paving block composition variation which is in accordance with SNI 03-0691-1996 was variation 4 with a composition ratio of 10% ceramic shard waste:20% landfill mining residue:50% sand:20% cement, which has meet the classification of quality C. The best values in the selected variation were a compressive strength test value of 21.69 MPa, water absorption test value of 3.16%, wear resistance test value of 0.169 mm/min, and a sodium sulfate resistance test score of 1%.
