In the present investigation, the Physical-Mechanical properties of a standard concrete were evaluated with respect to an experimental concrete, substituting cementitious material by Silico-aluminous ash, with resistance f'c = 210 y 280 kg/cm2, for the city of Trujillo. The trials of the physical properties of the aggregates were carried out in the laboratory of materials of UPAO; the ash chemical trials were analysed in the LASACI-UNT laboratory. This ash comes directly from the industrial Plant of the paper company Trupal. S.A. At the end of all the trials of the aggregates and the ashes, the design of mixtures was carried out based on the method of the ACI committee 211. The samples consisted on 4 x 8 plg circular specimens. Which were tested in substitution proportions of 5%, 10% and 15% with respect to the weight of the cement. The compressive resistance tests were carried out at ages 7, 14 and 28 days, for the tensile strength of the 28 day concrete and at the age of 263 and 270 days for the PH analysis of the sprayed concrete. Likewise, the physical properties of the Slump, Temperature and Unit weight were tested. Then, these experimental concrete were compared to a concrete pattern of different strengths f'c 210,280 kg/cm2. As final conclusion, it was obtained that the f'c 210kg/cm2 concrete with 5% ash substitution improves compressive strength by a 2.99% and tensile strength by 18.75%. For f'c 280 kg/cm2 concrete with ash substitution of 5%, 10% improves the compressive resistance by 9.71% and 1.17% and a 3.56% the tensile strength. In the results of the PH analysis of the pulverized concrete shows a decrease in the standard samples and those with least amount of silico-aluminous Ashes.
