Slags physicochemical properties

Accurate assessment of human health risks associated with oral exposure to metals requires knowledge of the fraction of the dose absorbed into the blood. This information is important for As-contaminated environmental media, such as soil and mine waste, because metal contaminants exist in a variety of soluble and insoluble forms and may be contained within particles of inert matrix, such as rock or slag. Physicochemical properties such as these influence the enteric absorption fraction (bioavailability) of ingested metals. Therefore, site-speciflc data on metal bioavailability in the environmental media of concern will increase the accuracy and decrease the uncertainty in human health risk estimates.

Recently, much has been done in the design and optimization of reaction protocols that allow for the controlled synthesis of chemically identical geopolymers that differ in the tendency to form crystalline fractions in the amorphous matrix [20,26,117]. The amount of crystalline phases, protocrystalline domains, and various structural defects, however, must be strictly controlled because their excess can lead to a loss of the required mechanical and physicochemical properties. This requirement is particularly important if waste products, such as colored kaoHn, slag, or fly-ash, are considered for use as input material [118-125].
