In Brazil we have a floor finish named Burnt Cement (that doesn't involve burning). Here is a description of the process
In summary, you use a mix of cement and pigment (sometimes marble powder too) sprinkled over fresh concrete floor (1 part cement and 3 parts sand), and then use a steel float to spread it. It can simply color, or have a stained effect.
What is this called in English?
Also, how can I properly execute this technique?
EDIT: From what I discovered, I think that is called dry-shake. In US people seem to buy a ready made compound to use, where in Brazil we mix cement and pigment (sometimes marble or limestone powder too) to make the same effect. If that is correct, I need to find some instructions on how to execute this (a video showing the effect would be even better).

Correct, dry shake. Or more specifically dry shake color hardener. As you say, it is essentially cement and colorant. You might just search video sites for application instructions, such as http://www.youtube.com/results?search_query=dry+shake+color+hardener+application. Incidentally, techniques that achieve similar effects to cured concrete are concrete dyes and concrete acid stains.
