Accordingly to Riley's ternary phase diagram for the preparation of ceramsite, the optimum composition of the raw materials is 40–79% SiO 2, 10–25% Al 2 O 3, and 13–26% fluxes (-CaO, MgO, Na 2 O, and K 2 O) [36].However, the RM used in this study has low silicon and aluminium contents and a high flux content; hence it is difficult to …

1. Introduction. In recent years, a large amount of sludge needs to be properly treated with the rapid development of urbanization (Zhang et al., 2023).Traditional sludge treatment mainly involves incineration, landfill, composting, and land use (Wang et al., 2024).However, each approach presents some drawbacks e.g. energy-consuming, high …

The expansion agent is perlite, at 10 wt.% addition. Finally, a ceramsite with bulk density of 340 kg/m, particle density of 0.68 g/cm3, and cylinder compressive strength of 1.02 MPa was obtained. Because of its low density and high porosity, ultra-lightweight ceramsite has excellent thermal insulation performance, and its strength is generally ...
