Abstract
This short article handles about the possibility of utilization of the fluid fly ashes in shielding materials. Because fluid fly ash is a waste and is being produced in large quantity, there is searched for alternatives in its usage. One of possible ways is e.g. its admixing into building materials. This is possible mainly due to chemical composition similarity between fly ash and some building materials. Scores of the time the fly ash is being added to the binder. In this work the fly ash was admixed to calcium hydrate and the resulting mixture was then used as a binder. But firstly it was necessary to ascertain chemical composition of the fluid fly ash and then to compute appropriate relation fly ash:calcium hydrate. After it, the designed binder was used into shielding mortar, which was subsequently tested on X-rays.
KEYWORDS: barite mortar, ionizing radiation shielding.
