The global aggregate is used in the industry of construction (sierra). It is characterized by being natural in the Earth's crust and used such which is extracted from the quarry of the Rio Bado, whose maximum size is 1““, the added thickness is rounded, the fine aggregate is River sand; This material is used in two ways; separating the thick and the thin by sieve n°4““ to prepare a specific pattern; also using concrete on a global basis. The water used in the research i s drinking water from the the UPAO testing laboratory facilities. The property of the global aggregate with concrete which facilitates its entrance is its permeability. In this study, tests were performed to measure its resistance, by applying additive Chema3. the present thesis is summarized in determining the characteristics and properties of the materials used by the '' fuller '' method, this is used Portland cement type Ico ““Pacasmayo““ whose specific weight is of 3150 kg/m³, the 28-day compressive strength, all the concrete called design (concrete pattern). Sets the design for aggregate global Rio Bado for relations them (0.40, 0.45, 0.50, 0.55), a/c recurred each mixture three times in order to have better results. With this test, a graph was prepared to establish the final design Fꞌc = 210 kg/cm², for relations 7, 14 and 28 days with additive and non-additive Chema3 in fresh state obtaining a slump of 3’’, With the results of this trial, curves and graphics vs relationship were developed w/c and vs relationship days. These results served to conclude that the initial design (concrete pattern) varies with respect to the w/b ratio, which in lower w/c relation greater resistance and the final design Fꞌc = 210 kg/cm increases the resistance to compression, with respect to the relationship in days, that a more days more resistance. This thesis has been determined to show that the additive generates more resistance in shortest time and that it is necessary for the shortest buildings.
