It was an alternative to stone. Instead of chiseling stones to the proper shape, the concrete was poured into a form and shaped. It was also easier to transport than stones weighing several tons. Concrete is prefab stone.
Roman concrete was made by mixing pozzolana (an active ingredient of volcanic ash or pumice) to make a binder and adding an aggregate to give it body. This varied according to the consistency or weight which was sought. For lighter concrete pottery sherds were used. Crushed bricks made medium weight concrete and crushed stone made heavy concrete. It was the pozzolana which gave the binder its strength. Roman concrete was as strong as modern concrete and also set underwater (therefore it was used to make docks). It was less fluid and had to be layered by hand.

An empire is not a person. Therefore, the Roman Empire did not invent anything. The Romans invented concrete. Roman concrete was different from modern concrete. It was more fluid and had to be layered by hand. It was just as strong.
The arch and the vault The Romans did not invent but did master both the arch and vault, bringing a new dimension to their buildings that the Greeks did not have. Domes Concrete As well as mastering and refining Ancient Greek geometrical learning, the Romans had their own wonder material. Concrete freed the Romans from building only with carved stone or wood.
Not to be picky, but I think you mean pencil. No, the Romans did not invent the lead pencil. In fact the "lead" in a pencil is not even lead at all. It is a material called graphite.
No, the Romans had water-cleansed toilets.

No, the Romans did not invent bricks, but they did invent concrete.
They did not invent new materials, but they engineered ways to make them work better, like the arch.
Concrete, Aqueducts, Baths, Central Heating and Roads.
Yes, because they were the first nation to make roads.
Yes, they did. It was the Roman's invention of concrete that made the dome possible.
