Abstract

This research was carried out with the objective of determining the mechanical and physical properties of compacted adobe by incorporating plant materials in its preparation. For which, 2.5% ichu fiber was used as a standard sample in comparisons to the use of three levels of pine fiber (2.5%, 5% and 7%). The compression, bending and absorption properties were analyzed for which 24 adobes were made for each of the indicated addition percentages; Obtaining, as an answer that the adobe with ichu fiber has better compression resistance 42.75 kg/cm², compared to 35.65 kg/cm², 34.68 kg/cm² and 28.95 kg/cm², for the levels 2.5%, 5% and 7% of pine fiber. When evaluating the resistance to flection, the adobes made at 2.5% with ichu fiber reached a resistance of 33.02 kg/cm², being greater than the resistance of: 27.07 kg/cm², 25.20 kg/cm² and 26.00 kg/cm² for 2.5 %, 5% and 7% pine fiber; Likewise, when evaluating the absorption of water, it was obtained as results that the adobe with Ichu fiber was 2.92% compared to 2.74%, 3.05% and 2.80% for 2.5%, 5% and 7% of pine fiber respectively. It is concluded: That the addition of 2.5% ichu fiber generates greater resistance to compression and flection, compared to the addition of pine fiber in 2.5%, 5% and 7%, but has lower absorption compared to pine fiber.
