    Effectiveness of polypropylene fibers on impact and shrinkage cracking behavior of adobe mixes
    (2019) Araya Letelier, Gerardo Andrés; Antico, Federico Carlos; Concha Riedel, José; Glade, Andres; Wiener, María J.
    Earth has been used as construction material for thousands of years and still at present earthen shelters are widely inhabited due to their comfort and low environmental impacts. Despite their advantages, earthen materials are brittle and their performance can be enhanced with the addition of fibers. This study addresses the use of different dosages of micro-polypropylene fibers in adobe mixes. The results show that adobe mechanical damage performance is sensitive to the dosage of polypropylene fibers increasing impact strength and reducing drying shrinkage cracking.

    Influence of jute fibers to improve flexural toughness, impact resistance and drying shrinkage cracking in adobe mixes
    (2019) Concha Riedel, José; Araya Letelier, Gerardo Andrés; Antico, Federico Carlos; Reidel Hanenstein, Ursula; Glade, Andres
    Flexural toughness, impact resistance and shrinkage cracking performance of earthen materials can be improved with the addition of fibers. There are limited studies addressing these properties in fiber-mixed adobe. This study investigates the use of jute fibers, a natural one derived from plants, in adobe mixes, including a sensitivity analysis on dosage and lengths of incorporated fibers. The results show that fiber-reinforced adobe’s flexural toughness and shrinkage are sensitive to the dosage, whereas impact resistance is sensitive to both fiber dosage as well as fiber length.
