Abstract

Waste mud generated during the construction of shield tunnels needs to be treated and cleaned before disposal due to its complex material composition. Various technologies are available for the treatment and disposal of waste mud, including sedimentation, filtration, centrifugation, incineration, and solidification. One promising solution is to recycle the waste slurry to produce bricks, which not only helps reduce environmental impact but also provides a cost-effective approach for disposal. The strength of bricks produced from waste mud is affected by several parameters, including the type and proportion of binder, mud properties, drying and firing conditions, and curing time. This study focuses on optimizing the compressive strength of test bricks by varying the formula of the curing agent, molding pressure, material moisture content, and curing agent dosage. The research provides valuable insights for improving the production process of the bricks. Waste mud from a construction site in Zhejiang Province, China, was used, and commercial-grade 525 Portland cement was utilized for hardening the mud into bricks.
