Crushed Slag

Slag that has been crushed into a fine gravel.

Notes

Crushed Slag is a fine gravel-like block produced by higher-level processing of slag, serving as a key ingredient in advanced construction materials such as Asphalt Concrete, Reinforced Concrete, and Fiber Reinforced Concrete, as well as in Bloomery and Stone Road recipes. As a solid, diggable block that can be carried on the back, it is heavy (24 kg) and stacks to only 10, so plan bulk transport and storage carefully when stockpiling for large paving or building projects.
