Effect of the content of the crystalline and vitreous phases of blast-furnace slags on their properties
Studies carried out on the hydrochannel granulation plant with a variety of blast-furnace slag from the southern Ukraine determined that, depending on their cooling conditions, it was possible to obtain materials with differing contents of the crystalline and glassy phases which have different porosities. These studies showed that, depending on the changes in these features, ordinary (solid) or porous granulated slag or slag pumice with different properties was obtained. The dependence of the hydraulic activity of the materials obtained (and cements based on them) on the cooling conditions of the melts (specific flow rates of water) has been shown to have an extremum and a maximum. The maximum value of the hydraulic activity has been determined to correspond to granulated slag which has a porous structure and contains 6-26% crystalline phase (mainly melilite), while the remainder consists of amorphous and devitrified glass, the content of the latter being of the order of 20-40%.
