Abstract

In this research, the main objective is to determine the compressive and flexural resistance of traditional adobe by adding 1.5%, 3.0% and 4.5% of cabuya fiber. In order to achieve this objective, different soil tests had to be carried out such as They are: moisture content, dry granulometric analysis, washing granulometric analysis, atterberg limits (liquid limit and plastic limit) and modified poctor. With the sole intention of having the necessary evidence and thus being able to make adobes, a mold or adobera with dimensions indicated in Standard E-080 was used, establishing measurements for the specimens and being able to present them in this investigation. A total of 60 artisanal adobes were made, of which 36 adobes were tested in compression and 24 adobes in flexion. The hypothesis states that the addition of cabuya fiber increases the compression and bending resistance by up to 5%. The results showed that the addition of cabuya fiber in the percentages of 1.5%, 3.0% and 4.5% reached a resistance of 13.71 kg/cm2, 15.37 kg/cm2 and 17.36 kg/cm2 respectively with an increase of 6.33% with respect to The standard sample obtained a resistance of 12.23 kg/cm2. With respect to bending, the results were 1.22 kg/cm2 for the addition of 1.5% of cabuya fiber, 1.72 kg/cm2 for the addition of 3.0% of cabuya fiber and 1.88 kg/cm2 for the addition of 4.5% of cabuya fiber with an increase of 9.82% with respect to the standard sample that was obtained of 0.82 kg/cm2, therefore we say that the hypothesis is fulfilled.
