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.

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

Structural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

Some observations on the calcium aluminate carbonate hydrates

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1960
Two calcium aluminate carbonate hydrates, previously reported in the literature, were prepared and various properties determined. The compound 3CaO·Al2O3·CaCO3·11H2O, was prepared by precipitation from mixtures of solutions of calcium aluminate, calcium hydroxide and sodium carbonate; and, in less pure form, by several other means.
