Most anything by David Weber. They are at least bricks but many are cinder blocks. Well there are a couple that are close to normal size but those are few.
I just bought "Virtues of War" by Bennett R. Coles it looks large. Maybe "HIs Father's Eyes" by David B. Coe is brick size
If you like short stories try one of the Mammoth books. I have Mammoth book of Steampunk. It's Cinder side. As it Epic Legends of fantasy edited by John Joseph Adams. He has a Wizard anthology that is huge too.
"Discovering Aberration" by S. C. Barrus looks big even though it is tradeback so may not be as big as it looks. It is steampunk with exploring an Island looking for what happen to a more advanced race of humans. There is a gangster in it and such.
