Influence of thermal conditions on the quality of unit bentonite sand from the point of view of oolitization of quartz grains

摘要

The paper deals with relation between temperature and oolitization level of silica base sand in the standard bentonite moulding mixtures (SBMM). Several model mixtures at various temperature conditions were prepared and their oolitization level was determined using changes in apparent densities method and dissolving in the orthophosphoric acid method. The goal is to determine the optimal conditions of creating the oolite layer.
