Paving block with product 1 material as a substitute of portland cement and landfill mining residue

Abstract

This research aimed to determine the CaO and SiO2 content in landfill mining residue and glass waste, variations of selected compositions in accordance with SNI 03-0691-1996 on Paving Block, and the best values of the selected composition variation as paving block raw material. The research consists of six test steps namely visible properties, size, compressive strength, water absorption, wear resistance, and sodium sulfate resistance test. X-Ray Fluorescence method was used to determine the value of CaO and SiO2 content in landfill mining residue and glass waste. The CaO and SiO2 content in landfill mining residue were 5.81% and 46.31%; glass waste values were 8.77% and 65.07%. The variations were landfill mining residue, glass waste, and product 1. Paving block composition variations 2, 3, 5 have met the SNI 03-0691-1996 classification of quality D, which is geared towards city park use and the paving block composition variation 4 with the classification of quality C, used for pedestrian walkways. The best values of the selected paving block composition are a compressive strength of 18.84 MPa; water absorption value of 3.41%; wear resistance value of 0.188 mm/min; and sodium sulfate resistance value of <1%.
