Construction

The contribution of cement and concrete to transportations and particularly to road construction is considerable. Bridges, tunnels, safety barriers, concrete roads and sound barriers are several examples of successful cement application. A characteristic of the use of cement in the aforementioned applications is the small maintenance cost together with the elongation of the service life of the structure. In road building, cement is also used for the treatment of aggregates and the stabilization of soils. The production of cement binding mixtures, contributes to the upgrade of the bearing capacity of sub grade along with an increase of the bearing capacity of the pavement layers. This increased bearing capacity provides the ability to construct road surfaces of lesser thickness and thus of a significantly lower cost.
