The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
Concrete is very important to the Romans because they were the first people who invented the hydraulic cement based concrete. The Roman did build very many concrete structures like the Pantheon in Rome.

simply workabilty is the w/c ratio in concrete. more the w/c ratio higher the workability and vice versa. and it is true that excess amount of w/c ratio doesnt give proper strength. so workable concrete i.e, concrete with proper w/c is must for good strength. *note: not considering the mix of concrete.
It means that you have to do it now. So if someone tells you a concrete command you better do it
to make it strong

The most important tool needed when making concrete is a concrete mixer. Once the concrete is mixed and lain it is also important to have equipment to smooth out the surface.

Paints to be used on concrete should be made especially for concrete. This is a very hard surface to cover and keep covered so it is very important a paint made especially for concrete is used.

Concrete language uses descriptions which create tangible images with details the reader can visualize. Its important to use concrete language because it is less open to multiple interpretations.

It is important to minimize the alkali metal content of concrete because concrete contains trace amounts of alkali metals like sodium and other minerals and if moisture is present then the sodium reacts with the minerals in the concrete, forming a gel and the gel may absorb water and expand causing cracks in the concrete.
Usually the sand and aggregate (filler stone) is the largest percentage of concrete, however from a chemistry standpoint the cement is, by far, the most important ingredient.
In the list of Roman accomplishments you mention, there was not one that can be singled out as the "most important". They all had different purposes so they were all important in their own areas. The laws were important in the civil area, the aqueducts in the health area, the concrete and arches were important in the construction area, the roads in transportation and the calendar in the time and record keeping areas.In the list of Roman accomplishments you mention, there was not one that can be singled out as the "most important".

There are several reasons, but corrosion protection and concrete spauling are probably the most important factors.
