Bond-Behavior of Bamboo Strips and Bamboo/Wood Bio-Concretes
Seeking the development of light structural elements with less environmental impact, the use of bamboo strips as bio-concretes reinforcement can provide an interesting solution in civil construction. Therefore, in order to use the bamboo strip with bio-concrete, it is important to understand the bond-behavior between both materials. This paper aims to analyze the bond-behavior of coated and uncoated bamboo strips with bamboo bio-concretes (BBC) and wood bio-concretes (WBC). The coating was made with a mixture of epoxy resin and sand on the lateral surface of the strips, and its effect on the adherence with bio-concretes was analyzed through the pull-out test. The bio-concretes were produced with a volumetric fraction of 40% of bio-aggregates and characterized through uniaxial compression and splitting tests. The results showed that, after 28 days of curing, the bio-concretes presented compressive strength of 6 MPa, and a tensile strength ranging from 1.14 to 1.23 MPa for both bio-concretes. As expected, the coated strips presented a bond higher with both bio-concretes than the uncoated. Comparing the bio-concretes, the force required to pull the coated bamboo strip from the BBC was greater than that of the WBC.
