Hello everyone,

I have decided to stop lurking and start my build thread. I have cut down a tree, dug a footing for a retaining wall and poured the footing thus far. Today as I was dry stacking the bricks for the retaining wall I discovered that the blocks were not 8x8x16 as I assumed, but 7 5/8" by 151/2". Since everything I know about masonry I have read here, and I was planning on incorporating my retaining wall into the form for the slab( 16" blocks work out perfectly if you stack them end to end for 80") So my question is: do I find blocks that are exactly 16" or do I mortar in between them?

Question 2: I have decided to use the homebrew hi temp mortar, any problem using fine beach sand? I hope not since I lugged home about 70 lbs of it today.
