Physical properties of magnesian lime mortars [PDF]

Materials and Structures, 2009
Magnesian lime is made from dolomitic limestone. The properties of magnesian lime mortars are not yet clearly established: some authors claim that Mg-lime has no hydraulicity and produces poor quality mortars that fracture, while others state that it produces quality hydraulic mortars.

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.

Medicine for the Material World

Archaeometry, EarlyView.
ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...
