Chemical Properties of Arsenic
Under ordinary conditions of temperature and pressure, arsenic does not coine directly with hydrogen unless the latter is in an activated or nascent condition. Three hydrides are known, however, two of which, hydrogen monarsenide, AsH or As 2 H 2, and the di-arsenide, As 2 H or As 4 H 2, are solid at ordinary temperatures, the third being the gaseous hydride, arsine, AsH 3, which is the most

Influencing factors on micromechanical properties of …
1/8/2020· In Portland cement-based concrete, calcium (alumino) silie hydrate (C-(A-)S-H) is the principal binding phase that governs its physical, mechanical, and durability properties. In this study, micromechanical properties of compacts made of synthetic C-(A-)S-H powder were investigated with nanoindentation, and various influencing factors were identified.
