"Another advantage of Magnesium-based cements are that they have a natural affinity for cellulose materials, such as plant fibers or wood chips; Portland cement repels cellulose. So you can actually use wood chips as an aggregate to achieve lighter weight and more insulative products."
Combined with basalt scrim, perhaps magnesium-cements could be used to resheath old wooden boats inexpensively, without the risk that ferrocement sheathing pose?
