This research studies medium to low strength concretes prepared with potable water and fine aggregate from the Trapiche - Lima quarry. The coarse aggregate from the Carapongo - Huachipa quarry. The plasticizer additive is Chema plast and Micro mineral SiO 400 is added. Portland Sol type I cement is used for the water-cement ratios 0.70, 0.65 and 0.60. The first tests correspond to the quality of the aggregates where their physical properties were determined. Subsequently, the chemical analysis of the additive Micro mineral SiO 400 was carried out. Following this, the mixture designs were made for the Standard Concrete (CP) with water-cement ratios of 0.70, 0.65 and 0.60. 4-inch settlements were obtained with the Maximum Compacted Unit Weight method of the aggregate combination. To these designs, a plasticizer additive (CPA) was added in an amount of 0.35% of the cement weight and the amount of water was reduced by a percentage to obtain 4-inch settlements. Finally, to these last designs Micro mineral SiO 400 was added in quantities of 5% and 10% of the weight of cement (CAM5 and CAM10). Once the 12 mix designs had been obtained, the tests of the concrete were carried out in a fresh state such as: Settlement, Fluidity, Unit Weight, Setting time and Exudation. In the hardened state, tests were carried out such as: Compressive Strength, Diametric Compression Tensile Strength and Elastic Modulus, highlighting the compressive strength tests. Finally, an interpretation and comparison of the obtained results is made, as well as a cost analysis for the 12 mix designs. An example of this is the use of Micro mineral SiO 400 at 5% (CAM5) and 10% (CAM10) that produces a reduction in the slump in the standard concrete with Additive (CPA) in the concrete.
