ABSTRACT: Crushed rock aggregate is commonly used as coarse aggregate in concrete and asphalt production. Fine aggregate could also be produced from crushed rock and it is one of the suitable materials identified for use on alternative to river sand. This material usually has a .

This study investigated the susceptibility of three subballast materials, which were made of different crushed rock aggregates, to convection: railway ballast (/63 mm), subballast layers of crushed rock, and 5/16 mm crushed rock. Convection was found to increase the thermal conductivity of railway ballast severalfold, while the thermal conductivity of the currently used subballast material ...

fragment size is the largest piece of rock that could be manhandled into a wagon. Such wastes, unless they were recrushed, would have been quite unsuitable for use as concrete aggregates. Most waste materials that were subsequently used as concrete aggregates were tailings products from various ore concentration processes.

Hornfels is a finegrained metamorphic rock that was subjected to the heat of contact metamorphism at a shallow depth. It was "baked" by heat conducted from a nearby magma chamber, sill, dike, or lava flow. Common temperatures for the formation of hornfels range from about 1300 to 1450 degrees Fahrenheit (700 to 800 degrees Celsius).
