I LIKE LIVING IN EUROPE. "IN CONCRETE" I LIKE LIVING IN SPAIN
If you look up (phrasal verb = buscar) the word "concrete" in an English dictionary you will see that it is a material that is used to construct roads and buildings.
It was a particularly fashionable (notice that you need to use "fashionable" NOT "fashion") material during the 1960s and early 1970s but then soon became seen as ugly. Spanish people like to use the words "in concrete" because they are thinking about "en concreto". Unfortunately, as can be seen from the definition above "en concreto" can not be translated using "in concrete"!
A much better translation is "specifically" or "in particular".
Hope that helps!
