Quick 1.0.1 update: Neglected to properly set minable results. Should now function correctly.

A simple add-on for Muluna that allows you to process regolith and crushed stone into primitive forms of concrete. The tiles are functionally worthless on any planet that doesn't have a slowdown applied to it, but on a surface like Muluna, the bonus is 0.7 for standard mooncrete and 0.8 for refined (Muluna's tiles apply a roughly ~0.67 movement speed). Both have a slightly-worse-than-vanilla speed boost for vehicles. I tried to base the recipes on actual proposals for a waterless lunar concrete using heat and sulfur as binders.

If you have Asphalt Roads Patched, adds an alternate recipe to produce asphalt from diluted bitumen and crushed stone.
