The research called: "Physical-mechanical characterization of a Portland cement concrete mortar type IP added with experimental additive EPS90, in the city of Cusco", consists of the addition of the experimental additive to the mortar mixture at 3%, 5% and 7% of the weight of cement, likewise samples were made without experimental additive EPS90. The first test that was carried out for the mortar in the hardened state was that of compressive strength, this test was carried out in accordance with NTP 334.051, in which the samples of mortar cubes with 50mm sides are subjected to a compressive force. The compressive strength of the 3% modified mortar gave us greater strength than the rest of the percentages. The second test that was carried out was shear adhesion, this test was carried out according to the Chilean standard (NCh)167, in the case of the 3% modified mortar carried out at 28 days of age, it gave us a higher resistance than the rest of the percentages, it should be noted that this test was carried out for 14, 21 and 28 days of age, noting that in the case of the 7% modified mortar at 14 days of age, adherence doubled with respect to the rest of the percentages and it was also observed that as age increases, this adherence remains almost constant for this percentage. The third test that was carried out was that of mortar fluidity, this test was carried out both to measure the fluidity of mortar cubes and shear adhesion, giving us a greater fluidity at 3% for both cases, this mortar being more workable than the rest of the percentages. The fourth test that was carried out was the setting time, this test was carried out for 3 temperature ranges, these being high, medium and low temperatures, the setting time of the modified samples increases the more experimental EPS90 additive it contains, also this varies according to the temperature at which it was made, in the case of low temperatures it gave us a longer setting time than the rest of the temperatures.
