free labor I vote for.

whats your budget? you could rent a cat, a jackhammer, use a sledgehammer.

I will hire a day laborer to do it. I am just wondering if a sledgehammer would work? If so, I will buy a sledgehammer, if it won't, I will rent a jack hammer.

the jackhammer will be easier on your body then the sledge hammer will be and do it a lot faster.

I use an abrasive saw and cut it up in sections then bust it up.
Then we scoop it up with a Skid loader and dump it into a dumpster.
Since you asking it's clear you have never done this before and have no idea what your in for.
Just trying to use a sluge hammer is never going to work out.

How big is this slab?
How do you plan on hauling it away?
Where do you plan on taking it?

if it's a freestanding concrete pad, i would just use a jack hammer.

if it is poured next to the house foundation, i would also rent a small demolition hammer like Makita HM1214c

good luck

rent an electric bosch brute breaking gun & 2" chisel bit from your local rental store - the apron/vest stores rent 40# guns which means harder work & longer rental periods - the 60# bosch still rules !

I rented that Bosch unit to crack open my basement floor to install a sump pump. It had awesome power, but everything in the house shook.

Few years later, I rented a small Makita to demolish my concrete patio step.

I went with Makita because I wanted a more controlled and accurate demolition to limit the transfer of any vibrations. You are right in that my demo project probably took about 4 hours longer than had I rented the Bosch unit.
