A cavity wall tie is a device for connecting a masonry leaf across a cavity to another masonry leaf or to a structural frame to resist tension and compression forces while allowing limited differential movement in the plane of the wall

Coke. Determination of coke reactivity index (CRI) and coke strength after reaction (CSR) subscription-only A cavity wall tie is1 Scope This document specifies the equipment and techniques used for determining lump coke (nominal top size >20 mm) reactivity in carbon dioxide gas at elevated temperatures and its strength after reaction in carbon dioxide gas by tumbling in a cylindrical chamber. Main application is the testing of coke to be used in iron making blast furnaces (CRI~ < 33, CSR~ > 55). This standard can also be applied to other coke types (e. g. foundry coke), but
