Only the aggregate.
An aggregate is the added material with the cement. For example: sand, crushed Styrofoam, straws (hay), broken/recycled glass, gravel, and sometimes recycled paper.
For houses, lighter aggregates are used, like sand or Styrofoam. Less weight helps in tall buildings and arches, like most Roman buildings. They used straws and lime (the mineral) on certain levels of their architecture.
For building foundations and paving, heavier aggregates are preferred, like gravel, stones or rock clay.
Oh, the thickness of the cement matters too.

I would suggest that it has something to with the mix ratios and the surface finish of the cement, the base cement will be the same product, but there will more larger chippings in the building mix thatn the pavement mix, as well as more sand. The moethid of pouring will diffent to as the larger the quantity of cement the longer the cure time. Building made from cement are poured in to shuttering or a system called Febrey.
thats about all i know, but try typing in cement mix ratios or speaking to a structuural engineer for more detailed info

Ok here's half an answer - its not different cement but the ratio mix of sand is different. I think the general mix of mortar for bricks is 1 cement : 3 sand. The general mix for paving slabs/foundations etc. is 1 cement : 5 sand (maybe inc some gravel).
Hope that helps - but just dont quote me - it may not be exactly right.

Most likely the grade of cement, eg, for roads, the cement would be thicker than that for housing.
Well, i hope this helps, it dosen't really matter whether it's right or not, it just matters that you tried =]

Sand in mix for house.
Gravel for roads.
