Cements and Clays

On Clays

Base-exchange determinations were made on selected clays of the montmorill0niteillite group to test this method as an analytical tool for the analysis of mixed-layer aggregates. The relatively rapid manganese method developed by Bower and Truog was used and its precision determined oll monodisperse, monomineralic fractions and monodisperse fractions of prepared mixtures of illite and montmorill...

Quartz cleavage and quick clays.

ESR of clays

Electron spin resonance (ESR) spectroscopy has contributed significantly to the identification and characterization pf paramagnetic impurities associated with clays, Following a brief discussion of the general principles of the technique, a review is given of the application of ESR to the study of those paramagnetic species (chiefly iron and radiation-induced lattice defects) located either wit...

Novel cements: low energy, low carbon cements

Sustainability and the UK cement industry Traditional Portland cement-based concrete provides the foundation for the built environment. Buildings constructed appropriately and imaginatively from this material can and do exhibit an impressive array of properties [1] especially those that have been designed to optimise the thermal mass of concrete [2]. This type of concrete building is expected t...

Chemical Characterization of Tablets, Sealing Clays, and Source Clays from Tell Leilan, Syria

When attempting to deal with questions involving the emergence and evolution of ancient complex societies, one of the major problems faced by researchers is how to monitor abstract processes from the material remains recovered in excavation. Clay sealings and tablets, which provide multiple independent lines of information: iconographic and/or epigraphic; functional (type of sealing i.e. door l...
