There is a brief section called "Water Production".

  That section can be safely ignored, because the proposed solution is not feasible, being based on non-lunar resources. Bringing hydrogen from Earth in quantities large enough to allow wasting it in construction materials, instead of using it only for making precious food and drinking water, for making water and acids used in certain chemical processes, for certain plastic materials used in small quantities and for fuel, is a completely impractical idea (this being a polite way of not calling such a solution for making construction materials on Moon as completely stupid). Hydrogen, nitrogen, carbon and sulfur will be the most expensive materials on the Moon, so they will be reserved for things where they are irreplaceable, not for construction materials, which are needed in huge quantities in comparison to the materials needed for any other application, so they must be made from the most abundant materials that can be found around.
