Promising! Good that somebody is looking into this. By far the most exciting development so far. A strange comment in the conclusions: "The interval between deep-source moonquakes is approximately 16.8 h. The final setting time of the geopolymer can be adjusted to less than 400 min. Therefore, the curing process can be completed within the interval between moonquakes." That makes sense only, only if the moonquakes are regular. If the interval is a distribution they'll have to be prepared for their curing to be disrupted and having to start over. By no means would there be any guarantee of curing reaching completion. 400 minutes is 6 or 7 of those 16.8 hours. Assuming a random distribution of moonquake intervals, that's maybe a one-in-three chance of curing-fail. Speeding up curing with light, heat or other additives is definitely worth looking into. If it could be halved, the curing-fails drop to a fraction e.g. maybe one in ten!
