Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

Achieving sustainable and durable concrete using high‐volume SiO2: Engineering properties, environmental and economic benefits

Structural Concrete, EarlyView.
Abstract This study explores the potential of high‐volume amorphous silica (SiO2) replacement for ordinary Portland cement (OPC) in concrete to reduce carbon emissions. Amorphous SiO2, such as silica fume (SF) and CO2 mineralization‐produced Si‐rich gel, offers superior properties to concrete but is under‐researched for its use in concrete with high ...
