ABSTRACT In the present research, were evaluated the influence of the cement’s stabilization and soil’s types in constructive adobes on their resistance to compression under equilibrium conditions, saturated with water, and their durability. The percentage of cement is: 0%, 3%, 6%, 9% and 12% of the total soil for the production of adobe units; the soil type was able to vary the sand and clay in 3 different proportions: the first between 55 - 70% of sand and 45 - 30% of silt - clay, parameters of the technical norm of construction (NTE) E.080; the second proportion of 50% sand and 50% silt - clay; And the third proportion of 75% of sand and 25% of silt - clay. The dimensions of the adobe are: width 12.5 cm, height 8.5 cm and length 21.5 cm. Before the analysis of the raw material and the formation of adobes, an evaluation of the adobes located in the area of Trujillo. The adobes of the research were elaborated by means of a manual forming applying a good molding so that the results were not affected by the elaboration process. The drying time was 27 days, where they were stored under cover. The best results of the research are obtained a stabilization of 12% of cement with a proportion of 75% of sand and 25% of silt - clay above that specified by the NTE E.080, with 48.2 kg/cm by compression at equilibrium conditions and 26.2 kg/cm by compression with water saturation for 24 hours. 2 It can be seen that the best combination of soil for an adobe without the need to use the cement as a stabilizer is 50% sand and 50% silt - clay giving a value of 25.7 kg/cm under equilibrium conditions since in a saturated state it was broken. 2 All stabilized adobes with cement have a good durability response to the presence of water in a static manner compared to a common adobe, since during the course of 7 days immersed in it only those added to 3% were affected in their shape and weight on losing Between 18.1 - 30.3% of material being the most affected the soil with more fines in its structure, however from 6% cement there is no weight loss, it is more these slightly increase their initial weight between 0.1 - 2.4%. It is possible to indicate that the adobes constructive without cement were undone in a matter of hours. Finally it has been shown that the addition of cement as a stabilizer improves the mechanical strength of the adobe and its durability from 6%. Although soils cannot initially be used for the production of adobe, their mechanical behavior can be improved by the addition of sand, reaching at least 50% of the same and provided that the clay content is adequate.
