how long will it work?

OK I'm 72 kg and 178cm......
I can do 30 pushups, then 25 and then 25......does this work for pec size?
 
To an extent. Use the search button. There are hundreds of threads on 'making pecs bigger.'

Buy a resistance band, wrap it over your back and hold in each hand to add resistance, you'll also be able to use the bands for things like flys.
Either that or put a plate on your back to lower the number of reps you're capable of doing in one set
 
80 pushups sounds a bit harsh. If you find them easy, then do some different stuff.

Try some different types of push ups:

Diamond - bring your hands close and form a diamond with your thumb and index finger

Wide grips - spread your hands out farther than normal

Or - you can just do flys along with pushups.
