Hi. I have a fallen piece from a foundational corner wall. I uploaded a photo.
Can you tell the type of cements used and how old are they?
Note: my home is built on 1960
Appears to be a fill or premix for material #1, ( hard to tell with Black and White) the other looks like a fill or finishing (surface) cement.
If you want to repair you will have to break open the area, create a Vee, or valley for material to adhere to. Just a word of caution, if you are going to create dust, wear a mask, and seal off the area. Back in the sixties, they at times put asbestos into the concrete.
is it possible to have the dark and white cement remain distinct since 1960? or some repair is done at some time.... Thanks
