Ok, more brick-like. It isn't what you think it is. It isn't subtractive manufactured, it is additive manufactured. Don't fool yourself, lava rock is several times stronger than steel and several times lighter. Well, technically, a specific type of lava rock and those are the characteristics of its polymer fiber.

basalt fiber is great stuff, but there is a lot of processing between what you dig up and the reinforcing fiber
