[Ferro List] Part 3/Tom's Crud/Passivisation

[Christopher Glasspool]

PART 3, THE LAST:
In my opinion what went wrong with your project isn't any single ingredient. I think you have ruled that out, but rather in the lack of an empirical approach and calculated testing. After the fact is bass akwards. While it is possible that some silly thing like a faulty water calculation is to blame, it is as likely a lack of skill in working with and around mortar in general. What should occur before any important project is started is that a compressive test of the mortar being used is done. This is fifteen dollars in my area. Test panels should be constructed....put them on top of saw horses and stand on them and more, take two hammers and bang from each side...exposing weakness, voids, bug holes, unmixed materials etc. 
I'm without a real workshop right now. The modular sheds I ordered missed the fall arrival date but are ready now. It is once again snowing hard here, so I wont be able to do any testing until late spring. I'm looking forward to exploring Tom's Crud Test. If I were you I would start a tank fix by not exploring the fix but by exploring the fc material itself. Make some panels using different methods and recipes. Take a slow approach of experimentation and I think the fix will most likely reveal itself. - chris
