KF-Ash will work to safely encapsulate Mercury Removal contamination.
For Mercury, KF-Ash is safe to use with a concrete mixture which contains Mercury contaminated raw materials.
Encapsulation of micro metal elements and particles is provided by their partial or complete oxidation into solutions of KALMATRON® KF-ASH with given high chemical potential under the water to cement ratio of 0.42.The petrography of that concrete may even exceed the modern standards of structural concrete or HPC. for chemically, biologically or radioactively contaminated products.

Regarding mercury and KF-Ash. For radiation shielding we can recommend KF-aby (admix). Also attached are trial results from several labs, and a cement plant that tested KC.
Mercury metal disperses spontaneously in water as micro-droplets
0.3 μm in diameter. Mercury metal dispersed spontaneously into the aqueous solution as micro-droplets when it came in quiescent contact with the solution. The self-dispersion was observed by means of the dynamic light scattering method, thermogravimetry and voltammetry. The mercury microdroplets generated in water had ca. 0.3μm in diameter. The diameter and the concentration of the droplets were stable. The concentration of mercury might be 1–3μmoldm⁻³ if the droplets were to be dissolved homogeneously in water. The concentration exceeds the environmental limits by three orders of magnitude. The dispersed mercury was confirmed not to be ions or oxide of mercury but to be metal droplets. The self-dispersion of mercury belongs to the self-emulsification at liquid|liquid interfaces without surfactants.
Mercury occurs naturally in the environment and exists in a large number of forms. Like lead or cadmium, mercury is a constituent element of the earth, a heavy metal. In pure form, it is known alternatively as "elemental" or "metallic" mercury (also expressed as Hg(0) or Hg0). Mercury is rarely found in nature as the pure, liquid metal, but rather within compounds and inorganic salts. Mercury can be bound to other compounds as monovalent or divalent mercury (also expressed as Hg(I) and Hg(II) or Hg2+, respectively). Many inorganic and organic compounds of mercury can be formed from Hg(II).
Elemental mercury is a shiny, silver-white metal that is a liquid at room temperature and is traditionally used in thermometers and some electrical switches. If not enclosed, at room temperature some of the metallic mercury will evaporate and form mercury vapours. Mercury vapours are colourless and odourless. The higher the temperature, the more vapours will be released from liquid metallic mercury.
Inorganic mercuric compounds include mercuric sulphide (HgS), mercuric oxide (HgO) and mercuric chloride (HgCl2). These mercury compounds are also called mercury salts. Most inorganic mercury compounds are white powders or crystals, except for mercuric sulphide, which is red and turns black after exposure to light. Some mercury salts (such as HgCl2) are sufficiently volatile to exist as an atmospheric gas. However, the water solubility and chemical reactivity of these inorganic (or divalent) mercury gases lead to much more rapid deposition from the atmosphere than for elemental mercury. This results in significantly shorter atmospheric lifetimes for these divalent mercury gases than for the elemental mercury gas.
When mercury combines with carbon, the compounds formed are called "organic" mercury compounds or organomercurials. There is a potentially large number of organic mercury compounds (such as dimethylmercury, phenylmercury, ethylmercury andmethylmercury); however, by far the most common organic mercury compound in the environment is methylmercury. Like the inorganic mercuric compounds, both methylmercury and phenylmercury exist as "salts" (for example, methylmercuric chloride or phenylmercuric acetate). When pure, most forms of methylmercury and phenylmercury are white crystalline solids. Dimethylmercury, however, is a colourless liquid.
Paints and Coatings Tightening volatile organic compound (VOC) content regulations and increasing health and environmental concerns about the use of heavy metals (e.g., chrome, lead, cadmium, mercury, zinc, cobalt, etc.) in the coatings industry, along with demand for improved physical properties and extended performance life, have spurred interest in silane technology
During the wintertime in the megacity Delhi, India, radiocarbon measurement of aerosols demonstrated that biomass burning/biogenic sources contributed 79% to water-soluble organic carbon (averaged to 35 ± 7% of total organic carbon), despite its numerous fossil air pollution sources (3)
