In this thesis the comparative evaluation between a concrete pattern f'c-210 kg / cm2 and a concrete made with volcanic rock in replacement of the coarse aggregate in percentages of 100%, 75% and 50% was carried out, performing compression tests at the 7, 14 and 28 days of the cylindrical witnesses and bending tests of the prismatic witnesses, the weight of these witnesses was also determined, all respecting the Peruvian Technical Standards. In the first place, the compression strength of the concrete and concrete made with volcanic rock was evaluated in replacement of the coarse aggregate in percentages of 100%, 75% and 50%, by means of cylindrical molds of 150 mm of diameter by 300 mm of height according to the MTC standard E 702-2000. Secondly, the flexural strength of the concrete and concrete with volcanic rock was determined in replacement of the coarse aggregate in percentages of 100%, 75% and 50%, these specimens were made with prismatic molds of 150 mm * 150 mm * 500 mm according to MTC E 702-2000 standard. Thirdly, both the cylindrical and prismatic witnesses of the different concretes were weighed, to be able to know how much the weight influences with respect to the strength of these concretes. Finally, the tests carried out were analyzed giving us results; The resistance to Compression: the concrete pattern reaches a resistance to 28 days of 264.09 kg / cm2, the concrete made with volcanic rock replaced by 100% the coarse aggregate at 28 days, reached 206.21 kg / cm2, the concrete made with volcanic rock replaced by 75% coarse aggregate at 28 days, reached 171.42 kg / cm2, concrete made with volcanic rock replaced by 50% coarse aggregate, at 28 days it reached 191.29 kg / cm2 ; Flexural strength: the concrete pattern arrives at a 28 day resistance of 1.14 MPa, the concrete made with volcanic rock replaced in 100% the coarse aggregate at 28 days, reached 0.98 MPa, the concrete made with rock volcanic replaced by 75% coarse aggregate at 28 days, reached 1.07 MPa, concrete made with volcanic rock replaced by 50% coarse aggregate, at 28 days it reached 1.03 MPa.
