INFLUENCE OF CALC -KREMNEZEMISTOGO BINDER ON THE PROPERTIES OF THE MOLDING MATERIAL MIXTURE IN THE PRODUCTION OF SILICA BRICK
Manufacture of silica brick typically is equipped with its own production of lime, which always has the siftings of crushing of limestone. For silicate materials autoclaved, the content of active Cao+MgO is directly dependent on the amount of input during grinding of quartz sand and lime quality. When evaluating lime should not forget about the content of the "underburning", on the material composition constituting the limestone. Taking into account the lime quality, the ratio of major components of silicate mass and content of active Cao+MgO in the binder you can change the content of active Cao+MgO in the molding mixture and by varying the composition of binder it is possible to reduce lime consumption by 23÷35%.
