The purpose of this professional sufficiency work is to evaluate the properties of cementsand concrete in a fresh and hardened state, using as an aggregate the sand of the Amazon River, which is being used in the Project: “Improvement of the Access Road to the AA.HH. Ciudad Jardín, AA.HH. Ampliación Ciudad Jardín and Caserío Cabo López, District of Belén – Maynas – Loreto“. The reason for the design of the cement-sand concrete is to evaluate the behavior of the Amazon River sand and, at the same time, make a comparison on the design used in the project in question, which will be used in this work as a standard design, as well as the design that appears in the Project’s technical file that will be used as a reference in the comparison of an unit prices analysis, and these will be compared with a design that we propose as an alternative, and see if the design used in the project is ideal and is not undersized or oversized. These samples were made using 4“ x 8“ PVC specimens, which were tested at 7 and 28 days, and the recommendations of the ACI COMMITTEE 211 were taken. The compressive strength will be taken as a variable, which, for this work, will be that of f’c= 210 kg/cm2. Two types of A/C ratios were made, one of 0.55 that is equal to the design used in the project, and another A/C ratio of 0.60 that we have proposed, since the first design used was overpassing the required resistance. From the results to the compression of the two A/C ratios tested, it was obtained that the A/C ratio of 0.60 is the most efficient, since the required compressive strength is reached using less cement, which, in the project in question for it’s size, represents a significant saving.
