Some Notes on Ancient Concrete

Concrete is a material composed of coarse granular particles embedded in a binder that glues the particles together. It is commonly believed that the ancient Romans were the first to create and use such material, but this is not true, as we can easily learn from the Latin literature itself. Without any doubt, Romans were able to prepare high-quality hydraulic cement, comparable with the modern Portland cement. In this paper we present some notes on the ancient concrete. From Rome, we will go back in time, showing how the Greeks used it in their Mycenaean royal palaces. The paper continues talking about an Egyptian concrete and ends discussing the use of concrete during Neolithic times.
