There are a number of concrete blocks on my property, a few fairly long that I need to break up.
I removed one of the smaller ones with an abrasive blade on my circular saw. Scored it and then split it with a hammer/chisel. However that wasn't very large and ate up the entire blade to slit it in enough places to make the chunks manageable.
I guess I'm wondering how the life of a diamond blade is, and is segmented better than continuous for old concrete.
