Abstract In this study, the dredged river sediment, soft texture and fine particles, is mixed with other materials and transformed into eco-friendly autoclaved aerated concrete (hereinafter referred to as AAC) blocks. The results indicated the bricks produced under the conditions of 30%–34% dredged river sediment, 24% cement, 10% quick
lime, 30% fly ash, 2% gypsum and 0.09% aluminum powder with 0.5 water to material ratio, 2.2 MPa autoclave
pressure and 6 h autoclave time, the average compressive strength of 4.5 MPa and average dry density of
716.56 kg/m³ were obtained, the two parameters (strength & density) both met the requirement of… More >
