Item Uso de cemento y savia de tuna como alternativas de revestimiento en muros de adobe para el mejoramiento de sus propiedades hidrófugas(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2020) Romero Yanzapanta, Andrés Paúl; Ureña Aguirre, Maritza ElizabethThis experimental work was carried out with land extracted from The Putzalahua Hill, which was analyzed by the Peruvian E0.80 standard as indicated by the NEC, laboratory tests were also carried out to obtain soil type, soil conditions and soil composition for adobe manufacturing. The traditional adobe blocks were developed in compliance with E0.80, the resistance of adobe blocks with an average value of 1.502MPa greater than indicated in the standard was checked, after the drying of the block, the resistance to contact with water in which the blocks do not resist, disintegrate, cracks and fissures are generated. Adobe blocks covered with tuna penca sap were made, resting for 7, 14 and 18 days; adobe blocks were also coated with cement in percentages of 5, 10 and 12.5 percent, in which very good results were observed, the coated adobe blocks were not disintegrated, in the absorption and suction tests. In tuna sap coating at 18 days reaches a suction of 22.66 gr/min/area with a capillary ascent of 1.08cm, and an absorption of 24.14 percent, because tuna penca sap decreases porosity, coated blocks also suffer a volumetric variation of 5.2 percent. Cement percentage coated blocks also withstand suction and absorption tests, cement at 12.5 per cent in suction was obtained a value of 48.05gr/min/area, the blocks absorb 36.04 per cent, and suffer a variation of 5.0 percent, but in contact with water they last better than traditional blocks. Finally, adobe walls coated with tuna sap were scaled at 14 days, 18 days and walls coated with cement percentages of 10 and 12.5 per cent; which were compared in the simulated flood test, the uncoated wall resists 1 hour 45 minutes collapses, while the walls covered with tuna sap 14 days resist 5 days and the wall with tuna sap 14 days resist 6 days without collapse, the walls covered with 10 per cent of cement and 12.5 per cent resist 7 days and 5 days respectively.
