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.

The strength and durability of concrete is heavily affected by what is in it. There are thousands of formulations for concrete, some with very specific applications. The most common key ingredient for concrete is limestone. Its properties were first put into use by the ancient Romans. After Rome fell, it took centuries for scientists to rediscover how to make concrete properly.
Sand was used only to lay the bottom layer of the bed of the stone-paved roads. The Romans used Roman concrete. This type of concrete was different and, unlike modern concrete, sand was not used to make the mix.

Hollow concrete tile blocks were first used soon after the ancient Romans developed concrete. It was not very strong, but it was strong enough to be a tile.

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.
