If the aggregate cement ratio of a concrete mix is increased:
When the weight of cement is more, i.e. aggregate-cement ratio is less, the concrete has more cement paste required to coat aggregates and fill the voids between them. Thus more cement paste makes the concrete relatively easy to mix, place, and compact as it reduces the friction between aggregates and allows its smooth movement.
