You peaked our interest - looks like very good testing but you forgot to explain the results - what do I do with my 1900 building with crumbling brick?
The results are published in some journal articles. Basically, the ferrocement jacketing would be the most favorable method in terms of strength and ductility. www.sciencedirect.com/science/article/abs/pii/S2352710219307466?via%3Dihub The results can also be seen from the videos below: ua-cam.com/play/PLSnDMdaGKqNpVO0NzPLd8TWzNDD5_etSw.html Regarding your building, I would suggest to consult to a local structural engineer as there are many factors to be taken into consideration before suggesting and strengthening interventions.
Ferrocement jacketing provided the best results in terms of strength and ductility. Then polypropylene fibers scored a high strength but limited deformation capacity. C-FRP needs extra preparation of the surface and had good strength and good deformation capacity. The lowest strength was G-FRP but it had a satisfactory deformation capacity.
The steel mesh (ferrocement) was attached on both sides using mechanical anchors and improved the shear strength as well as ductility of the specimens.
All the techniques are applied on both sides externally. In this way you do not affect the conditions of the existing wall. But it has to be applied on BOTH sides (inside and outside) of the building.
There are no codes regarding strengthening of URM using FRP. Depending on the FRP material characteristics and the type of improvement you want to see, you should design a proper configuration of the strengthening technique. A good option can be by following the previous literature done in fibre reinforced polymers field.
I was expecting more explicit results of how each technique behaved.

Really cool stuff my friend.👍👌🏼
Great work.
So in summary. What was the best to worse materials to use to strengthen the walls ?
Ferrocement jacketing provided the best results in terms of strength and ductility. Then polypropylene fibers scored a high strength but limited deformation capacity. C-FRP needs extra preparation of the surface and had good strength and good deformation capacity. The lowest strength was G-FRP but it had a satisfactory deformation capacity.
Nice video
in the video i didnt understand the behvior of the wall with steel net. can you explain? it was from both sides?
The steel mesh (ferrocement) was attached on both sides using mechanical anchors and improved the shear strength as well as ductility of the specimens.
i only have acess from outside (exterior), it Also improve the wall?
All the techniques are applied on both sides externally. In this way you do not affect the conditions of the existing wall. But it has to be applied on BOTH sides (inside and outside) of the building.

thank you
please tell me what are the used codes for strengthening of masonry by FRP?
There are no codes regarding strengthening of URM using FRP. Depending on the FRP material characteristics and the type of improvement you want to see, you should design a proper configuration of the strengthening technique. A good option can be by following the previous literature done in fibre reinforced polymers field.
What was the result? Which was the strongest?
Ferrocement jacketing had the most satisfactory results.
