| Abstract |
| Granulometry plays an important role in deciding the ultimate
properties of any material, be it refractory or concrete
or other materials which need compaction. Porosity is intimately
related to granulometry which in turn controls other
physical and thermomechanical properties of refractories.
Lower porosity yields dense products and this is achieved
through controlled grading of the input materials. The grading
must be continuous where all the fractions are present,
which is never possible in gap grading. The present study
is an effort to reduce the apparent porosity through control
of grading of the input materials and to correlate other properties
with porosity of a refractory. |
