Production — Stalite

At high temperatures of over 2,200 degrees F (1,200 degrees C), diabase rock (specific gravity of 3.0) melts to a glassy type of rock with no specific gravity change. Because this high specific gravity creates havoc on a desired lightweight specific gravity material, it should be avoided totally.


bulk specific gravities of crushed aggregates and cylindrical rock cores from six limestone quarries, one slag, one crushed trap rock, and one synthetic aggregate (Synopal) were determined by five methods. The methods are standard ASTM, geometrical measurement, mercury dis­ placement, and two chemical indicator methods proposed by the authors.
