The purpose of this research is to evaluate the influence of the addition of industrial microsilica such as Sika Fume and Silica Fume QS, on the resistance to compression and capillarity, in mortars made with type V cement, with cement: sand ratio of 1: 3 and 1: 4, with percentages in addition to cement from 0% to 10%, with a water / cement ratio of 0.65 and 0.70; adding at the same time the accelerator additive Accelguard 80 of QSI with 1.5% addition, using coarse sand from the quarry "Lekersa" of Huanchaco. Developed under the standards: American Society for Testing and Materials (ASTM) and American Concrete Institute (ACI), granulometry (ASTM C136 and NTP 400.012), humidity (ASTM 566 and NTP 339.185), specific gravity and absorption (ASTM C128 and NTP 400.022), loose and compacted dry unit weight (ASTM C29 and NTP 400.017), compression (ASTM C109) and capillarity (ASTM C1585). Test pieces of 5cm x 5cm x 5cm were prepared, where they were cured in calcium hydroxide solution at 7, 28 and 56 days, with a total of 756 cube specimens, obtaining as a result, the best resistance to 28 days in mortar. conventional, was the dosage c: a of 1: 3, with 259 kg / cm , the specimens at 28 days, added with Sika Fume microsilica had a better resistance being 8% the most optimal percentage with 401 kg f / cm with a 1: 3 ratio, increasing 54.2% resistance based on the resistance pattern, concluding that the mortar added with sika microsilica fume improves has high initial resistance with a low absorbency that decreases the capillary fringe in the mortar. On the other hand, the mortar added with silica fume silica QS, has good results at 28 days with 8% addition with 385 kgf / cm 2 2 of resistance being a mortar of good quality, but of unstable growth, its capillarity becomes absorbency medium, this is due to the particle size of the microsilica, causing more water to be absorbed. The capillarity of lower absorbency is in 8% addition and in dosages between 6% and 9% addition, from the group of mortars added with Sika Smoke microscope and Accelguard 80 accelerator additive, obtaining mortar mixtures of low absorbency.
