Characterization of LUSI Mud Volcano as Geopolymer Raw Material

摘要

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 are SiO_2 and Al_2O_3 which are higher than those in fly ash. The particle of mud 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 have the chemical bonding between bands 1-5.
