In the present research work, the durability of cement mortars has been evaluated, evaluating two variables: the action of the a / c ratio and the addition of a microsilica additive in order to obtain a less porous and impermeable product; applying a factorial design. In the development of the thesis the data obtained in the laboratory regarding the absorption rate was experimented, observed, evaluated and systematized. The mortars were made with fine aggregate from the "Piedras Gordas" quarry located in the Pan American Highway Km 565, downtown the miracle village, district of Huanchaco in the province of Trujillo; Likewise, Pacasmayo Antisaltpeter cement MS and Sika Fume hydrophobic additive were used. To this end, the properties of the materials used were characterized, the specimens were prepared and the tests were carried out following an experimental matrix of the factorial design 32. The specimens following the activity based on the ASTM C 192 standard were cured until completing the 7 days of setting. In the laboratory of floors II and pavements of the school of Civil Engineering in the Faculty of Engineering of the Private University Antenor Orrego. The test method was used to determine the rate of water absorption (sorptivity) in the cement mortar, measuring the increase in the mass of a specimen as a result of the absorption of water as a function of time when only one surface is exposed to water. of the test tube. The levels of the a / c ratio were 0.40, 0.45 and 0.50 and the percentage levels in weight of the microsilica additive were 5, 10 and 15%, the treatment time was 7 days. The lowest absorption rate (sorptivity) obtained was 807 g / (m2.h) that is to say 0.001345 g / (cm2.min) for an ratio of a/c 0.4 and 15% by weight of microsilica additive, in a test period 7 days
