The results showed that the single ceramsite compressive strength, water absorption, bulk density, and porosity of ceramsite sintered at 1180 °C with 1.0% SiC were 2.15 MPa, 2.02%, 490 kg/m3, and ...
However, whether RS from contaminated sites is safe for ceramsite production still remains unknown. To date, a risk assessment has not been clearly made. To facilitate the resource reuse of and promote the construction of sponge cities, here, we evaluated the effects of ceramsite serving as urban street cushion by a small-scale …
The use of ceramsite to construct filtration systems (e.g., biofilters) is a common method for water treatment. To promote such applications, the development of low-cost, high-performance, and environmentally friendly ceramsites has received increasing attention from scientists, and a critical step in the development is the …
High-strength ceramsite was prepared from red mud, fly ash, and bentonite without any other chemical additives by a two-stage sintering process.
