THE INFLUENCE OF THE ADDITION OF SAND TO DUNE CRUSHED IN CEMENT OR STABILITY OF CONCRETE.

The influence of the addition of sand to dune crushed in cement or stability of concrete resulted

essentially tow effects: One effect is physic mechanical and the other effect is chemical caused by

chemical reactivity in cementations medium, in certain mineral phases, characterized by

pouzzolanics and hydraulics property, the effects concerned simultaneously on materials

performances: mechanical resistance, physical property and performances durability. Also a third

physic effect concerning the relative granule effect to cause the modifications by the presence of

fines particles to the solid Shelton of the mixture.
