The best definition of concrete I heard was 'liquid stone'. And that's the way the Romans used it. In Reculver in Kent in England I was able to examine some Roman concrete close up in a fort and was astonished by its hardness considering it was 2,000 years old and close to the sea. My father was an architect and once told me the Romans used whites of eggs in their concrete mix to give it adhesion, strength and hardness.

Why were houses not built with concrete in the middle ages?

People of the Middle Ages did not know how to make concrete. The ancient Romans had concrete, but the secret of how to make it may have been lost. So there was a time from the middle of the fifth century for about 1300 years when no concrete structures were built. Even if the secret had been recorded, the fact that no one was using it meant it was lost for all practical purposes.
