Characterization of LUSI Mud Volcano as Geopolymer Raw Material A Review

Abstract

The mud of mud volcano samples were collected from an eruption site named ‘LUSI’ (Lumpur “mud†–Sidoarjo), East Java, Indonesia for characterization. Analysis showed that, the major constituents of mud volcano are SiO2 and Al2O3 which is are higher than those in fly ash. The particle of mud volcano has a flake-shaped particle and the overall particle size is dominated by particles between 2.5µm – 25.0µm. The results of XRD shows that mud of mud volcano have a characteristic of structurally disordered compounds, and a set of peaks corresponding to minor crystalline phases such as quartz, feldspars, and kaolinite. FTIR adsorption bands of the raw material of mud volcano has the chemical bonding between bands 1-5
