Physical properties testing. Physical properties are widely used to classify refractory materials. 1. Bulk density. It’s a measure of a product’s overall quality. The weight-to-volume ratio, expressed in g/cm3. 2. Porosity. It is the ratio of the volume of its pores to the overall volume of the body.

3.5.2 Aggregate ‘Ten Percent Fine Value’ (TPFV) The other way of representing the strength of aggregate is the ‘ten percent fine value’ (TPFV), which is basically the load required for 10% fines. As compared to aggregate crushing value test this test is more reliable for representing the strength of aggregate.
