BASIC MATERIALS FOR HIGH-STANDARD HYDROTERMAL CONTAINED FORMS AND PREPARATION OF SAD MATERIAL

摘要

A starting material for the manufacture of shaped and hydrothermally hardened products is composed of a binding agent comprising finely-divided olivine having a specific outer surface of at least 25 000 cm2/cm3, measured according to the permeability method, and finely-divided silica material in a quantity which is at most equal to the solid volume of said olivine and a ballast material in an amount of 50 - 80% by volume of the starting material and comprising particulate ultra-basic rock or slag material having a particle size of 80% smaller than 200 - 1000 mu m.
