Good go I go there ... evening mortar refractory ... Awesome
Pffffuuuuuuuuuuuuuuuuu it took me more than 2h ... lying in the dirt ... the intervention was worse than I thought ... I had to disassemble the whole right because it was wobbly! I had to repair to the blind while touching ...
Small photo report!
The right part moved a lot, I decided to turn everything to start on a healthier basis ... I did not need a tool to remove the blocks ... it is to say that it was afraid! So there were leaks on this level suddenly!
At the access level, the refractory bricks are 60 mm thick, for you to locate the dimensions ...
We see that I did not do that well at the time, it lacks mortar!
As the chimney was "open", it allowed me to take a picture of the galva tubing of the duct (blind please), I would try to remove the dirt from the repair by the hatch of sweeping later .. .
I also benefit as it is dismantled to take a picture of the conduit (bottom right is the access of the hatch sweeping):
Result after almost 2h on the right side (to fumble with the hand in the dark ... I do not say that I do not like groping in the dark but not with mortar full of the fingers
The left part was easier, some joints to strengthen only:
Before the intervention and especially when the fireplace was "open", I heard strongly the draw (there is heavy wind tonight), once closed much less ... it's a good sign!
ps: for Ahmed, what you thought was "plaster" is not, it's not either the cell concrete glue (siporex) I tried to remove the hammer, it's a classic concrete with very hard gravel, probably the top floor screed that drooled? We see it on the right picture finished ...
