Edit - okay so apparently we know what the materials are but we don't know the exact recipe - because there wasn't an exact recipe. how it was made basically changed from worker to worker and was wildly inconsistent so while good mixes will make buildings that lasted thousands of years even while dealing with the weathering of the ocean, the bad mixes would make structures that collapsed, based on records, within decades if not years. So while it's totally possible to make Roman concrete, how decent that concrete is changes based entirely upon what miracle mix you managed to pull off.
