Concrete, in construction, structural material consisting of a hard, chemically inert particulate substance, known as aggregate (usually sand and gravel), that is bonded together by cement and water.
For the wastewater studied, the initial fraction of inert particulate organic matter (xXI) was negligible, while the initial fraction of inert soluble organic matter (xSI) was 20.94% ± 1.65.

The importance ranking based on the sensitivity measures demonstrates that the most influential factors involve ash content and influent inert particulate COD among others, largely responsible for the uncertainty in predicting sludge production and effluent ammonium concentration.
In vitro quartz stimulated more production of cytokines by alveolar macrophages than the inert particulate titanium dioxide.
Particle densities were described by a function that considered two parts of each particle: the resin-core part consisting of resin and inert core-particulates, and the thin resin film part without inert core-particulates.
For this purpose, an experimental procedure was developed to quantify the inert soluble (SI) and particulate (XI) COD fractions, as well as the readily (SS) and the slowly (XS) biodegradable COD fractions.
Then, it is seen that the thermal decomposition of SOF adsorbed on the particulate matter leads under inert atmosphere to the formation of a microporous carbonaceous layer at 600 °C.
Once released from a coating, copper hydrates and/or complexes with a variety of species in natural seawater environments, including the hydrated free copper ion (Cu2+), dissolved organic (labile and inert) and inorganic complexes, colloidal and particulate copper (Morel 1983).
