The use of construction residues and demolition contributes directly two benefits: It avoids the need to extract natural materials and solves the problem of the spillages of the above mentioned residues. Indirectly it helps to reduce the emission of pollutant gases. You will study in this thesis the physicist - mechanics properties to aggregate recycled (fine and coarse), from manual trituration the samples concretes of the constructions in Lima city, and you will study to properties physicist - mechanics of the concrete in condition fresh and hard, it was elaborated entirety with recycled aggregate. This thesis for an valuation of the properties of the aggregate recycled (fine and coarse) they are compared with similar properties of natural aggregates; in case of the concrete they are elaborated three designs with the natural aggregate and cement " Sol I type " with slump of 3-4" and relations water - cement: 0.45, 0.5 and 0.55; being obtained respectively 445, 508, 604kg of cement by cubic meter of concrete; with these quantities of cement were elaborated three designs with 100% of the aggregate recycled (fine and coarse) they are equal slump and type of cement of the concrete pattern. The principal results of the tests to the aggregates recycled in comparison with the pattern are: increase of the absorption of the fine and coarse aggregate to 639 % and 867 % respectively, decrease of the specific weight of the fine and coarse aggregate to 19.5 % and 10.9 % respectively. The principal results of the tests of the concrete recycled in comparation with the pattern for cement quantities of 445, 508, 604 kg/m3 they are decrease the resistance to the compression to 28 days in 2.7 %, 7.3 % and 9.7 % respectively, the absorption to 28 days is increase in 5 %, 19 % and 29 % respectively, the weight of the concrete fresh is decrease in 5.2 %, 5.2 % and 4.8 % respectively.
