Fine-Grained (Sand) Concrete for the Construction of Cement Concrete Road and Airfield Pavements

The problem of using fine-grained (sand) concrete instead of the "classic one in the construction of road and airfield pavements is analysed. In sand concrete the coarse aggregate, crushed stone or gravel, are substituted by natural sand or a blend of natural sand and screenings 0.5 (10) mm. The use of sand concrete is efficient from the economic, the ecological and the technical point of view, reduces the expenses of producing the concrete and the rock masses are protected without the properties of the concrete pavement being impaired.
