Resumen
Presently investigation work, evaluates the use of arid recycled and fine recycled in the
production of structural concretes.
Once selected the raw mix in the plant in Alamar, made the characterizations in the
Technical Center for the Development of the Materials of Construction (C.T.D.M.C.), of
the necessary materials to produce hydraulic concretes. It decided that the substitution
percent of coarse natural, will by 25% and 100%, fine natural sand was substituted
50%, and add of filler 3% and 6 smaller% that the sieve 200.
In the stage of production of concretes, the properties were evaluated in fresh state, as
the establishment and their density. In the age of break of 7 and 28 days, they were not
carried out rehearsals destructive and destructive. Inside those no destructive
sclerometer and ultrasound, and inside of the destructive resistance to compression.
Inside the conclusions that you arrived, it stands out that the use of arid recycled and
fine recycled, it facilitates the obtaining of acceptable results in the production of
structural concretes.
