ABSTRACT Concrete is one of the most commonly used materials in our local environment and it is known that this material increases its resistance over time. This research aims to determine the variation of the compressive strength of concrete specimens designed with fc = 210 kg / cm², developed by ACI method, using this quarry aggregates in a river Chonta later than 28 days cure (age at which reaches 100% of its strength) period; it should be emphasized that the type of curing used is curing type "immersion". What was done was standard concrete specimens with ACI method with aggregates "quarry of Chonta River," for which first had to determine the physical properties of both the coarse aggregate (Ag) as fine aggregate (Af). Subsequently the mix design was performed with the ACI method and then formulate concrete specimens. Then he left them and heal the rehearsed with the following results; 28 days (standard sample) of 209.76 Kg / cm² equivalent to 100%; 35 days of 217.35 Kg / cm² equivalent to 103.62%; 42 days of 219.04 Kg / cm² equivalent to 104.42%; at 49 days of 220.04 Kg / cm² equivalent to 104.90%; and at 56 days of 220.22 Kg / cm² equivalent to 104.99%. With this might validate the hypothesis.
